3 to 30 Ton Hydronic Heat Pumps

Green, Eco Friendly, Renewable Energy ECONAR GeoSystems is the only North American manufacturer of ColdClimateTM GeoSource heat pumps. ColdClimates demand comfortable, efficient heating while not compromising cooling or humidity control. ECONAR ColdClimate GeoSource heat pumps deliver.

The GeoSource Ultra utilizes R410A refrigerant, a chlorine-free HFC refrigerant that does not harm the earth’s protective ozone layer. Hydronic heating systems have become much more popular in recent years by providing extremely comfortable concentrated warmth where you want it, without the air movement or noise of a conventional system. When radiant heating comfort is coupled to ECONAR’s hydronic heat pump’s efficiency where C.O.P.’s over 5.0 or 6.0 can be achieved, you have the ideal heating system.

ECONAR’s hydronic heat pump transfers energy from the earth-coupled heat source. Our water-to-water heat pumps supply heated or chilled water for use in a wide range of heating and cooling applications. A water/antifreeze solution circulates through the hydronic heat pump, supplying energy to any number or types of external heat exchangers.

Hydronic Side Applications

Radiant floor heating The most popular form of hydronic heat is radiant floor heating. This method maintains the heat comfortably near the floor eliminating drafts. Very high efficiencies are achieved by consistently supplying a large floor mass with low tempera-ture heat. Applications range from heating a comfortable cozy family room, the whole house, your garage or shop, to heating a church and your large office or commercial warehouse.

Fan Coils Fan coils coupled to the GeoSource heat pump pro-vide conditioned air to one or more comfort zones. Sizing is based on air temperature and flow rate. These systems can be extremely economic and versatile means of zoned temperature and humidity control for applications such as large homes, office spaces, schools, community buildings, libraries, churches and hotels.

Other Applications Many other hydronic applications such as swimming pools, hot tubs, tank heating, base board/finned tube, and ra-diators are easily sized based on temperature, flow rate, heat dissipation, and add to the numerous possible uses of ECONAR hydronic heat pumps.

I. INTRODUCTION TO ECONAR HEAT PUMPS

ECONAR Energy Systems, Corp. has been producing geothermal heat pumps in Minnesota for over fifteen years. The cold winter climate has driven the design of ECONAR Energy System's heating and cooling equipment to what is known as a "Cold Climate" geothermal heat pump. This cold climate technology focuses on maximizing the energy savings available in heating dominated regions without sacrificing comfort. Extremely efficient cooling, dehumidification and optional domestic hot water heating are also provided in one neatly packaged system. Geothermal heat pumps get their name from the transfer of heat to and from the earth. The earth coupled heat exchanger (geothermal loop) supplies the source energy for heating and absorbs the discharged energy from cooling. The system uses a compression cycle, much like your refrigerator, to collect the earth's energy supplied by the sun and uses it to heat your home. Since the process only moves heat and does not create it, the efficiencies are three to four times higher than the most efficient fossil fuel systems. ECONAR produces three types of geothermal heat pumps: hydronic heat pumps, which transfer heat from water to water; forced air heat pumps, which transfer heat from water to air; and combination heat pumps, which incorporate the hydronic heating of a water to water unit into a forced air unit. This guide discusses the GeoSource Ultra hydronic units. The GeoSource Ultra utilizes R-410a refrigerant, an HFC refrigerant that does not harm the earth’s protective ozone layer. ECONAR's hydronic heat pump transfers energy from the earth-coupled heat exchanger to hydronic heating and cooling equipment. Water-to-water heat pumps have the ability to supply heated or chilled water for use in a wide range of heating and cooling applications. Safety and comfort are both inherent to, and designed into ECONAR Energy System's geothermal heat pumps. Since the system runs completely on electrical energy, your entire home can have the safety of being gas free. The best engineering and quality control is built into every ECONAR heat pump built. Proper application and correct installation will assure excellent performance and customer satisfaction. ECONAR's commitment to quality is written on the side of every heat pump we build. Throughout the building process the technicians that build each unit sign their names to the quality assurance label after completing their inspections. As a final quality test, every unit goes through a full run test where the performance and operation is verified in both the heating and cooling

modes. No other manufacturer goes as far as to run a full performance check to assure system quality.

** IMPORTANT** Service of refrigerant based equipment can be hazardous due to system pressure and 230 volt electrical energy. Only trained or qualified service personnel can install, repair or service refrigeration equipment.

Warning - Turn off the main power before performing service or maintenance to this unit. Electrical shock can cause personal injury. The installer is responsible to see that all local electrical, plumbing, heating and air conditioning codes are followed.

II. UNIT LOCATION/ MOUNTING

Locate the unit in an indoor area where the ambient temperature will remain above 45oF. Servicing of the heat pump is done primarily from the front. Rear access is desirable and should be provided when possible. A field installed drain pan is required under the entire unit where accidental water discharge could damage surrounding floors, walls or ceilings. Units must be mounted on a vibration-absorbing pad slightly larger than the base to provide isolation between the unit and the floor. Water supply pumps should not be hard plumbed directly to the unit with copper pipe; this could transfer vibration from the water pump to the refrigeration circuit, causing a resonating sound. Hard plumbing could also transfer vibration noise from the unit through the piping to the living space.

CAUTION - Before driving screws into the cabinet, check on the inside of the unit to be sure the screw will not hit electrical or refrigeration lines.

III. EARTH LOOP WATER PIPING Since water is the source of energy in the wintertime and the energy sink in the summertime, good water supply is possibly the most important requirement of a geothermal heat pump system installation. There are two common types of water supplies, closed loop systems and open loop systems. A. Closed Loop Applications A closed loop system recirculates the same water/ antifreeze solution through a closed system of underground high-density polyethylene pipe. As the solution passes through the pipe, it collects heat (in the heating mode) that is being transferred from the relatively warm surrounding soil through the pipe and into the relatively cold solution. The solution is circulated to the

3

heat pump, which pulls heat out of the solution, and then back through the ground to extract more heat from the earth. The GeoSource Ultra is designed to operate on either vertical or horizontal closed loop applications. Vertical loops are typically installed with a well drilling rig up to 200 feet deep or more. Horizontal systems are typically installed with excavating or trenching equipment approximately six to eight feet deep, depending on geographic location and length of pipe used. Earth loops must be sized properly for each particular geographic area, soil type, and individual capacity requirements. Contact your local installer or ECONAR’s Customer Support for loop sizing requirements in your area. Since normal wintertime operating entering water temperatures (EWT) to the heat pump are from 25oF to 32oF, the solution in the earth loop must include antifreeze. GTF and propylene glycol are common antifreeze solutions. GTF is methanol-based antifreeze, which should be mixed 50% with water to achieve freeze protection of 10oF. Propylene glycol antifreeze solution should be mixed 25% with water to obtain a 15oF freeze protection. DO NOT mix more than 25% propylene glycol with water in an attempt to achieve a lower than 15oF freeze protection, since more concentrated mixtures of propylene glycol become too viscous at low temperatures and cannot be pumped through the earth loop. Insufficient amounts of antifreeze may result in a freeze rupture of the unit, and can cause unit shutdown problems during cold weather operation (when the heat pump experiences the longest run time) due to loop temperatures falling below the freeze protection of the loop solution. Flow rate requirements for closed loops are higher than open loop systems because water temperatures supplied to the heat pump are generally lower (see Table 1). Between

Figure 1 – Closed Loop Water Plumbing

2.5 to 3.0 gallons per minute (GPM) per ton are required for proper operation of the heat pump and the earth coupled heat exchanger. Pressure/Temperature (P/T) ports should be installed in the entering and leaving water line of the heat pump on a closed loop system (see Figure 1). A thermometer can be inserted into the P/T ports to check entering and leaving water temperatures. A pressure gauge can also be inserted into these P/T ports to determine the pressure differential between the entering and leaving water. This pressure differential can then be compared to the specification data on each particular heat pump to determine the flow rate of the system. A PumpPAK that is individually sized for each application can supply pumping requirements for the earth loop fluid. The PumpPAK can also be used to purge the loop system. The PumpPAK is wired directly to the contactor and operates whenever the compressor runs (see Electrical Diagram – Figure 7). If a PumpPAK is not used, a separate pump can be used which is energized with a pump relay (note: electrical code will require a fused disconnect for pumps other than PumpPAKs). Filling and purging a closed loop system are very important steps to assure proper heat pump operation. Each loop must be purged with enough water flow to assure a two feet per second flow rate in each circuit in the loop. This normally requires a 1½ to 3 HP high head pump to circulate fluid through the loop to remove all the air out of the loop and into a purging tank. Allow the pump to run 10 to 15 minutes after the last air bubbles have been removed. Enough antifreeze must be added to give a 10oF to 15oF freeze protection to the earth loop system. This amount should be calculated and added to the loop after purging is complete. After antifreeze has been installed it should be measured with a hydrometer,

4

refractometer or any other device to determine the actual freezing point of the solution. Remember that a low antifreeze level will lock the heat pump out on low pressure during wintertime operation. The purge pump can be used to pressurize the system to an initial static pressure of 30 to 40 psi. Make sure the system is at this pressure after the loop pipe has had enough time to stretch. In order to achieve the 30 to 40 psi initial pressure, the loop may need to be pressurized to 60 to 65 psi. This static pressure will fluctuate from heating to cooling season, but the pressure should always remain above zero so circulation pumps do not cavitate and air cannot be pulled into the system. For information regarding earth loop installations contact your local installer, distributor or factory representative. Table 1 – Loop Side Flow Rates Model Closed Loop Open Loop

A well must be available that can supply all of the water requirements (see Table 1) of the heat pump along with any other water requirements drawing off that same well. The well must be capable of supplying the heat pump’s required flow rate for up to 24 hours per day on the coldest winter day.

Figure 2 – Open Loop Water Plumbing

Figure 2 shows the necessary components for water piping of an open system. First, a bladder type pressure tank with a "draw down" of at least 1½ times the well pump capacity must be installed on the supply side of the heat pump. Shut off valves and boiler drains on the entering and leaving water lines are necessary for future maintenance issues. A screen strainer is placed on the supply line with a mesh size of 40 or 60 and enough surface area to allow for particle buildup between cleanings. Pressure/Temperature (P/T) ports are placed in the supply and discharge lines so that thermometers or pressure gauges can be inserted into the water stream. On the well water discharge side of the heat pump, a flow control valve must be mounted next to the heat pump to regulate the maximum water flow through the unit. A solenoid valve is then installed and wired to the accessory plug on the controller. This valve will open when the unit is running and close when the unit stops. A visual flow meter is then installed to allow visual inspection of the flow requirements. The flow meter is useful in determining when maintenance is required. (If you can't read the flow, cleaning is required. See Water Coil Maintenance for cleaning instructions.) Schedule 40 PVC piping, copper tubing, polyethylene or rubber hose can be used for supply and discharge water lines. Make sure line sizes are large enough to supply the required flow with a reasonable pressure drop (generally 1" diameter minimum). NOTE: Do not use plastic female fittings with metal male fittings, or fractures may result in the female fittings. Always use plastic male into steel female!

Water discharge is generally made to a drain field, stream, pond, surface discharge, tile line, or storm sewer.

CAUTION: Using a drain field requires soil conditions and adequate sizing to assure rapid percolation, or the required flow rates will not be achieved. Consult local codes and ordinances to assure compliance. DO NOT discharge water to a septic system. The heat pump should never be operated with flow rates less than specified. Low flow rates or no flow may result in freezing water in the water to refrigerant heat exchanger. This will cause the unit to shut down on low-pressure lockout. If the unit locks out, verify that the unit has the required flow and reset the unit by shutting off power to the unit for one minute. DO NOT continually reset the unit; if the unit locks out more than once call your service professional. Continued reset of the unit can freeze water inside the water coil to the point of rupturing the water coil. 1. Open Loop Freeze Protection Switch Heat pump installations on open loop systems, using a non-antifreeze protected water source during the heating mode, require the use of a freeze protection switch. If the water supply to the heat pump is interrupted for any reason, continued operation of the compressor would cause the water remaining in the water-to-refrigerant heat exchanger to freeze and rupture the copper inner tube. The freeze protection switch (ECONAR Part # 30-2020) will shut the unit down before freezing can occur and protect the heat pump in case of loss of flow. A freeze protection switch must be field installed on open loop GeoSource Ultra heat pumps before the warranty can be registered on the heat pump. The switch mounts on the compressor’s suction line and is wired to terminals on the controller (from X to FP). After the freeze protection switch is installed, the J4 jumper must be removed from the controller to activate the switch. The low pressure switch now locks the unit off at 65 psi pressure in the heating mode. 2. Water Coil Maintenance Water quality is a major concern for open systems. Problems can occur from scaling, particle buildup, suspended solids, corrosion, pH levels outside the 7-9 range, or biological growth. If poor water quality is known to exist in your area, a cupro-nickel water coil may be required when ordering the system, or installing a closed loop system may be the best alternative. Water coil cleaning on open loop systems may be necessary on a regular basis. Depending on the specific water quality issue, the water coil can be cleaned by the following methods:

a. Freeze Cleaning (Scale deposits, particle buildup)

I. Before using the freeze cleaning procedure, verify that it needs to be done. Answer the following questions to determine if servicing is required. 1. Determine and verify that the required water flow

rate in GPM is both present and correct. 2. Determine the temperature differential of the

water. Under normal conditions, there should be a temperature difference of about 10-15 degrees between the supply side and discharge side. If the temperature difference is 8 degrees or less, consideration should then be given to cleaning the water coil heat exchanger.

II. If cleaning of the water coil is indicated, please carefully follow the steps listed below to utilize the freeze cleaning method.

1. Turn off the heat pump and its water supply. 2. Open a plumbing connection on the water supply

side, if possible, to break the system vacuum and allow easier drainage of the system and water coil.

3. Drain the water out of the system and water coil via the boiler drains on the entering and leaving water lines, and the drain on the heat exchanger.

WARNING!! FAILURE TO COMPLETELY

DRAIN THE WATER COIL HEAT EXCHANGER COULD POSSIBLY RESULT IN A FREEZE RUPTURE!

4. Set the thermostat to "Heat" to start the heat pump in the heating mode and quickly freeze the coil.

5. Allow the heat pump to run until it automatically shuts off on low pressure and then turn the thermostat to the "Off" position.

6. Recap the water coil drain and tighten any plumbing connections that may have been loosened.

7. If so equipped, open the field installed drain cock on the water discharge side of the heat pump, and install a short piece of rubber hose to allow drainage into a drain or bucket. A drain cock on the discharge side allows the water flow to bypass the solenoid valve, flow valve, flow meter, or any other item that may be clogged by mineral debris. Drainage to a bucket helps prevent the clogging of drains and allows you to visually determine the effectiveness of the procedure.

8. Turn on the water supply to the heat pump in order to start the process of flushing any mineral debris from the unit.

9. Set the thermostat to "Cool" and start the heat pump in the cooling mode to quickly thaw out the water coil.

10. Run the heat pump until the water coil is completely thawed out and any loosened scale, mineral deposits, or other debris buildup is flushed completely from the water coil. Allow at least 5 minutes of operation to ensure that the water coil is thoroughly thawed out.

6

11. If the water still contains mineral debris, and if the flow through the unit did not improve along with an increase in the temperature difference between the water supply and discharge, repeat the entire procedure listed above.

12. Reset the heat pump for normal operation.

b. Chlorine Cleaning (Bacterial Growth) 1. Turn the thermostat to the "Off" position. 2. Connect a submersible circulating pump to the

hose bibs on the entering and leaving water sides of the heat exchanger.

3. Submerse the pump in a five-gallon pail of water and chlorine bleach mixture. The chlorine should be strong enough to kill the bacteria. Suggested initial mixture is 1 part chlorine bleach to 4 parts water.

4. Close the shut off valves upstream and downstream of the heat exchanger.

5. Open the hose bibs to allow circulation of the bleach solution.

6. Start the pump and circulate the solution through the heat exchanger for 15 minutes to one hour. The solution should change color to indicate the chlorine is killing the bacteria and removing it from the heat exchanger.

7. Flush the used solution down a drain by adding a fresh water supply to pail. Flush until the leaving water is clear.

8. Repeat this procedure until the solution runs clear through the chlorine circulation process.

9. Flush the entire heat pump system with water. This procedure can be repeated annually, semiannually, or as often as it takes to keep bacteria out of the heat exchanger, or when bacteria appears in a visual flowmeter to the point the flow cannot be read. Another alternative to bacteria problems is to shock your entire well. Shocking your well may give longer term relief from bacteria problems than cleaning your heat exchanger, but will probably need to be repeated, possibly every three to five years. Contact a well driller in your area for more information.

c. Miratic Acid Cleaning (Difficult Scaling and Particle Buildup Problems)

1. Consult installer due to dangerous nature of acids. 2. Iron out solutions and de-scaling products are also

useful.

IV. HYDRONIC HEAT EXCHANGERS A. Radiant Floor Heating Hydronic side heat exchangers can be a variety of different types. Probably the most popular form of hydronic heat exchangers is radiant floor heat tubing.

Radiant floor heating gives excellent comfort and very high efficiencies by supplying low temperature water to the floor slab, and keeping the heat concentrated evenly near the floor. Radiant floor systems heat the occupants and surfaces directly with radiant energy. Forced air heating moves heated air around the building, which transfers the heat to the occupants. Air movement can create drafts, temperature stratification, and air rising to the ceiling, which must be considered when designing heating systems. Always remember that hot air rises, heat does not. Radiant floor heating usually consists of 1/2 inch plastic tubing, approximately one linear foot of pipe per square foot of floor space. This value is doubled for one pass along the outside walls to concentrate more heat in this area. The tubing is generally laid into the concrete slab floor of the building. New construction techniques have also made installation into wood floors and suspended floors possible. The amount and spacing of the tubing is sized to meet the capacity of the space at a certain fluid temperature inside the tubing. To optimize efficiency and capacity, the fluid temperature inside the tubing should be maintained as low as comfortably possible. The type of floor covering and the spacing of the pipe in the floor have the greatest effect on operating fluid temperature. Table 2 gives a rough estimate of expected operating temperatures for specific floor coverings: Table 2 – Expected Operating Floor Temps

Floor Covering Temp (oF) Carpeting 115 Tile/Linoleum/Hard Wood 100 Concrete/Quarry Tile - Residential 85 Concrete/Quarry Tile - Commercial 70 ECONAR designs its hydronic heat pump line using a 115oF leaving water temperature design point. This leaving water temperature is the ideal maximum fluid temperature for radiant floor systems. Operating temperatures higher than this would result in an uncomfortable hot feeling in the conditioned space. In fact, boilers connected to radiant floor heating systems must be restricted to a 115oF maximum operating temperature by mixing valves or other control devices. Distributors of radiant floor heat exchanger tubing can help size the length of pipe and fluid temperature required for your specific radiant floor heat exchanger applications. Be sure to include insulation under the slab and around the perimeter. Two inches of polystyrene under the slab and two to four inches on the perimeter down to a four-foot depth are required. This insulation reduces the heat loss to the ground and decreases the response time of the heating system. Building insulation is important in radiant floor heating, as in other methods of heating. Poorly insulated buildings can result in higher floor temperatures needed to heat the building, which could exceed the level of human comfort.

7

Night setback thermostats are not recommended on radiant floor systems due to the response time of the slab. Radiant floor systems are not usually recommended for cooling, since cold, clammy floors and poor dehumidification may result. To provide cooling to a radiant floor heating installation, the installation of a fan coil unit is recommended. Another alternative is a GeoSource DualTEK heat pump. B. Fan Coils Fan coils can be used with ECONAR's hydronic heat pumps in the heating and cooling mode. In many cases, radiant floor heating and fan coil cooling are used together. Fan coils also provide dehumidification in the cooling mode. The rate of dehumidification can be adjusted by varying the fan coil operating temperature. Fan coils are available in many different sizes and configurations, making them very flexible to your particular application. Valence heating and cooling systems, which use natural convection to move air, can also be very versatile.

Note: When selecting fan coil units for cooling use, make sure they include condensate pans. Fan coils are sized for capacity at specific water temperature and flow rate combinations. Their sizing is also based on air temperatures, airflow rates (which remain constant based on fan speed selection and static pressure differential), and humidity conditions. The fan coils are then matched to the heat pump at a common system flow rate and operating temperature to provide the overall system capacity to a space load. High static pressure fan coils have recently come onto the market, which work well with ECONAR's hydronic heat pumps. These systems provide heating and cooling for houses without ductwork. They use a high static pressure blower to supply air through small tubes, which run through chaseways to the living space. The blower passes air though a water-to-air coil that is coupled to a hydronic heat pump to provide heating and cooling. These systems work nicely on retrofit applications where ductwork isn't available or wanted. Fan coil data is available in Table 5.

C. Baseboard Heating Another application of hydronic heating is finned tube baseboard heating. This is the same tubing used with boilers with one major difference. The discharge temperature of a boiler is much higher than geothermal heat pumps. The heat pump system should be sized at 115oF hydronic leaving water temperature to maintain efficiency. At a 125oF hydronic leaving water temperature, the heat pump is at a maximum operating temperature and may start to trip off on high head pressures. Standard 3/4" finned tube baseboard conductors have an average output of 230 Btuh/ft at

120oF hydronic leaving water temperature. In most cases there is not enough perimeter area in the conditioned space to allow for the required length of tubing to handle the entire heating load. There have been successful installations using baseboard as supplemental heating but many factors must be considered. Cast iron radiators have been used successfully. If these radiators are rated for an output of 70 Btuh/square inch at a 130oF hydronic leaving water temperature, they work well with geothermal systems. Although the radiator may be rated at 130oF, the system should still operate at the standard 115oF leaving water temperature of the water-to-water heat pump. D. Other Applications Additional open loop hydronic applications such as outdoor swimming pools, hot tubs, whirlpools, tank heating, etc. are easily sized based on heat exchanger operating temperature and flow. The worksheet in Appendix 1 was taken from the ASHRAE 95 Applications Manual and can be used for outdoor swimming pool sizing. In many instances, sizing a heat pump to these applications comes down to recovery time. The larger the heat pump (within reason to avoid short cycling) the faster the system recovery time will be.

Note: Installing a plate heat exchanger (see Figure 6 for an example) between the heat pump and an open system is required when corrosive fluid is used in the open loop, especially on swimming pools where pH imbalance can damage the heat pump. Note: Expect the maximum operating temperature of an indirect coupled application to be 10oF below the maximum operating temperature of the heat pump. Other forms of closed loop systems such as indoor swimming pools, pretreated fresh air systems, snow melt systems, and valance heating/cooling systems are also very common with hydronic heat pumps. The sizing of the heat pump to these systems is more precise and information from the system manufacturer is required.

V. APPLICATIONS OF HYDRONIC HEAT EXCHANGERS This section deals with some common practices used when coupling the ECONAR GeoSource Ultra hydronic heat pumps to the space conditioning heat exchanger. There are so many possible applications for hydronic systems that they cannot all be covered in this text. Hopefully these ideas can help in many of your system designs.

Note: Actual systems must be constructed to all appropriate codes and according to accepted plumbing practices.

A. Storage Tanks Coupling the heat pump to the space conditioning heat exchanger through a water storage tank is very common. In fact, the only instance where these storage tanks are not recommended is when the heat pump is coupled to a large heat exchanger capable of absorbing the entire heating or cooling capacity of the heat pump (see Figure 5). In applications that use multiple smaller zones, storage tanks absorb the relatively large amount of energy supplied by the heat pump, in order to provide longer run times and less compressor cycling for the heat pump. Storage tanks also serve to dispense energy in small amounts so that the conditioned zones have time to absorb heat without requiring high discharge water temperatures. Insulated hot water heaters are commonly used for storage tanks.

Note: While all hot water tanks are insulated on the top and sides, many do not have insulation on the bottom. An insulated pad beneath uninsulated tanks will reduce energy loss to the floor. When properly sized, a storage tank eliminates many problems with multiple zone hydronic systems. These problems include excessive leaving water temperature if a single zone cannot dissipate heat quickly enough, and hydronic flow reduction through the heat pump when only one zone is calling. This may occur because the hydronic circulating pump is normally sized to provide the heat pump’s required flow with all zones calling. When sizing storage tanks to the heat pump, a good rule of thumb is ten gallons of storage tank per ton of hydronic capacity. The tank temperature can be controlled with a simple aquastat or a setpoint controller. The setpoint controller senses tank water temperature and outside air temperature to increase the tank temperature as the outside air temperature goes down. This control scheme provides the highest heating efficiencies by requiring the lowest possible water temperature to heat the space. Setting the optimal design temperatures in the controller is difficult, and the simple aquastat does have its advantages. To help in setpoint control, the following equation can be used. Reset Ratio = Design Water Temp – Indoor Design Temp Indoor Design Temp – Outdoor Design Temp Always check local codes to be sure hot water heaters can be used as storage tanks. Using the electric elements in the tank as a secondary heat source to the heat pump is appealing in some applications, but special UL listing is required by many local codes. Specially listed hot water heaters are available. B. Hydronic Side Circulators Hydronic circulator pumps transfer the energy supplied by ECONAR's hydronic heat pumps to the space conditioning heat exchanger. When selecting a circulator, be sure to select a quiet operating pump with the ability to supply the required flow rate at the system pressure drop.

The circulator supplying the heat pump should be placed in the water supply line into the unit to provide the best pump performance. Individual zone circulators should also be placed in the supply lines of the heat exchangers they serve. These pumps are often used as the on/off control mechanism for the zone they supply as shown in Figure 4. Zone valves are also commonly used for this purpose using a common pump (shown in Figures 3 and 6). Note: Select a common pump at the total flow of all the zones and the highest pressure drop of any one parallel zone. Small Grundfos pumps (230 VAC) can be used as circulator pumps. These pumps are impedance protected and do not require additional fusing if powered directly from the heat pump, since the heat pump is rated to accept up to a 1/3 horsepower circulator. If impedance protected pumps are not used, inline fuses should be supplied according to code. Pumps must be sized to provide the required flow to a heat exchanger at its corresponding pressure drop. This pressure drop can be calculated from the total pressure drop through the piping, added to the pressure drop of the space conditioning heat exchanger. The hydronic side pressure drop through each particular heat pump is listed in Table 3. This table can be used for sizing the circulating pump between the hydronic side of the heat pump and a storage tank. Table 3 – Storage Tank Circulators

Hyd. Loop Grundfos Series Flow (gpm) dP (psi) Circulator

This table represents the minimum pump sizing required to supply the heat pump's required hydronic side flow rate at the pressure drop of the heat pump and 30 feet of 3/4" type K copper tubing or combination of elbows and pipe. A common problem with circulator pumps is trapped air in the system. This air accumulates in the suction port of the circulator causing cavitation in the pump, which leads to premature pump failure and noisy operation. The air can be eliminated by completely purging the system or by placing an air separator in the plumbing lines. The entire system must be purged of air during initial installation and pressurized to a 10-25 psi static pressure to avoid air entering the system. This initial static pressure may fluctuate when going from the heating to cooling modes but should always remain above zero. If a leak in the system allows the static pressure to drop, the leak must be repaired to assure proper system operation. Air continually entering the loop can cause corrosion, bacteria, or pump cavitation.

The hydronic side circulator supplying the heat pump should be controlled to run only when the compressor is also running. If the pump is allowed to circulate cold water through the system during off cycles, the refrigerant in the heat pump will migrate to the hydronic side heat exchanger. This can cause heat pump starting problems (especially when this refrigerant migrates into the condenser). C. Circulation Fluid The fluid circulating through the hydronic side of the geothermal heat pump system is the transfer medium for the heating and cooling being supplied to the conditioned space. Selection of this fluid is very important. Water is the most readily available fluid but has the drawback of expansion during freezing which can damage the system. System operation in the cooling mode, extended power interruption to a structure, or disabling of an outside zone (such as a garage floor) provides the opportunity for freezing the circulating fluid. Antifreeze must be used whenever the possibility of freezing exists from the environment or from use of the unit in the cooling mode. A propylene glycol based antifreeze (readily available through HVAC wholesalers) and water solution is recommended. Methanol based antifreeze is not recommended for use on any hydronic system where heat is being added to the system for structural heating purposes. Freeze protection for the hydronic side fluid down to 20oF (20% propylene glycol by volume in water) is recommended for most indoor applications (see Chart 1). Forty percent propylene glycol in water (-5oF freeze protection) is recommended by radiant tubing manufactures for snow melt applications, in order to protect the tubing from expansion in outdoor applications. Using over 40% in hydronic side applications can cause pumping problems due to high viscosity. The water being added to the system should have 100-PPM grain hardness or less. If poor water conditions exist on the site, softened water is recommended, or acceptable water should be brought in. Bacteria or algae growth in the water is a possibility, especially bacteria or algae that thrive at the particular temperatures produced in the heating system. This growth can cause buildup on hydronic side heat exchanger surfaces, reducing the efficiency of the system or causing the heat pump to run at higher head pressures and possibly lock out. Adding a gallon of bleach or boiler system conditioner can reduce the possibility of growth and clean up visual flow meters and other components in the system.

Chart 1 -Propylene Glycol/Water Solution Freeze Point D. Expansion Tanks Expansion tanks must be used in the hydronic side of the water-to-water system to absorb the change in pressure of the closed system due to the change in temperature when heat is supplied to the system. Diaphragm-type expansion tanks should be used. The diaphragm in these tanks is filled with pressurized air which expands or contracts to maintain a constant overall system pressure as the fluid in the system expands with increasing temperature. Use EPDM diaphragm tanks because they are compatible with glycol-based antifreeze fluids (butyl rubber diaphragms will slowly dissolve with glycol-based antifreezes). Tanks from 1 to 10 gallons are generally used with heat pump systems in residential and light commercial applications. Expansion tanks should be installed in the system near the suction of the circulator pump whenever possible. This maintains positive pressure at the circulator pump and reduces the highest working pressure of the system. A pressure gauge near the inlet of the expansion tank gives a good indication of how the system is operating. Pressure relief valves are required on all hydronic applications. A 30 psi relief is adequate if the system is operated at 12 to 15 psi pressure. If a hot water heater is used for a storage tank, the 150 psi pressure relief may be acceptable (check local codes). E. Application Diagrams Figures 3 through 6 show the components of a hydronic heat pump system discussed above used in some common applications. These figures by no means represent all the possible hydronic heat pump applications, but they do show some important principals that can be applied to any system.

VI. UNIT SIZING Selecting the unit capacity of a hydronic geothermal heat pump requires four things:

A) Earth Loop Configuration and Design Water Temperatures.

B) Hydronic Side Heat Exchanger Operating Temperatures.

C) Building Heat Loss/Heat Gain. D) Temperature Limitations

A. Earth Loop Configuration and Design Water Temperatures Loop configurations include the open and closed loop varieties. Heat pump flow rate requirements vary depending on loop configuration (see Table 1). Consult ECONAR’s Engineering Specifications Manual for capacities at different loop entering water temperatures and hydronic leaving water temperatures. 1. Closed Loop Systems Closed loop systems use a heat exchanger of high density polyethylene pipe buried underground to supply a tempered water solution back to the heat pump. Closed loops operate at higher flow rates than open loops since the entering water temperature (EWT) is lower. The loop EWT supplied to the heat pump has a great effect on the capacity of the unit in the heating mode. Earth loops in cold climates are normally sized to supply a wintertime EWT to the heat pump from 32oF down to 25oF, which minimizes the installation cost of the earth loop and still maintains proper system operation. The GPM requirements and pressure drops for loop pump sizing are shown in Table 1. 2. Open Loop Systems On an open loop system the design water temperature will be the well water temperature in your geographic region. Many cold climates are in the 50oF range for well water temperature. If your well water temperatures are lower than 50oF, for instance Canadian well water can be as low as 43oF, the flow rate must be increased to avoid leaving water temperatures below the freezing point. If well water temperatures are above 50oF, as in some southern states where well water temperatures are above 70oF, the flow rates may need to be increased to dump heat more efficiently in the cooling mode. Varying well water temperatures will have little effect on unit capacity in the cooling mode (since the well is connected to the heat pump condenser), but can have large effects on the capacity in the heating mode (since the well is connected to the evaporator). If well water temperatures are to exceed 70oF, special considerations, such as closed loop systems, should be addressed.

B. Hydronic Side Heat Exchanger Operating Temperatures The hydronic side heat exchangers discussed in section IV are designed to operate at a specific fluid supply temperature. This operating temperature will have to be supplied to the selected space conditioning heat exchanger by the hydronic heat pump. The manufacturers or distributors of the hydronic side heat exchangers publish the capacity of their equipment at different operating temperatures and fluid flow rates. These capacities and operating temperatures are required to select the heat pump to be used in the system. When selecting the heat pump, choose a unit that will supply the necessary heating or cooling capacity at the minimum and maximum hydronic loop temperature conditions respectively. Example; if a fan coil system requires 42000 Btu/hr to cool a space with 45oF water temperature entering the water-to-air fan coil, a GW47x GeoSource Ultra heat pump is required to handle the cooling load. If an intermediate heat exchanger is used between the storage tanks as pictured in Figure 6, expect a 10oF operating temperature difference between the two tanks. For example, if the direct coupled storage tank is at 115oF, expect the maximum operating temperature of the tank connected through an intermediate heat exchanger to be 105oF. This occurs when connecting open loop applications to the closed loop systems with plate heat exchangers or with indirect water heaters. C. Building Heat Loss/Heat Gain The space load must be estimated accurately for any successful HVAC installation. There are many guides or computer programs available for load estimation including the ECONAR GeoSource Heat Pump Handbook, Manual J, and others. After the heat loss/heat gain is completed, loop EWT’s are established, and hydronic side heat exchanger conditions are determined, the heat pump can now be selected using the hydronic heat pump data found in the Engineering Specifications. Choose the capacity of the heat pump based on both heating and cooling load. D. Temperature Limitations Be aware of the operating range of the geothermal system when sizing the particular heat pump. An operating range of 15oF (minimum for heating) to 110oF (maximum for cooling) is required for the earth loop side. These limits have been established based on efficiency limitations and safety pressure switch limits (50-psi low-pressure cutout and 580-psi high-pressure cutout). Hydronic side limitations in heating have a minimum of 50oF HYD entering water temperature and a maximum of 125oF HYD leaving water temperature range (entering water to the hydronic side below 50oF gives low head pressures

13

that drives the suction pressure below cutout conditions). Hydronic side limits in cooling fall into the 25oF entering water temperature range.

VII. ELECTRICAL SERVICE The main electrical service must be protected by a fuse or circuit breaker, and be capable of providing the amperes required by the unit at nameplate voltage. All wiring shall comply with the national electrical code and/or any local codes that may apply. Access to the line voltage contactor is gained through the knockouts provided on either side of the heat pump next to the front corner. Route EMT or flexible conduit with appropriate 3-conductor wire to the contactor.

WARNING - The unit must be properly grounded!

CAUTION: Three-phase units MUST be wired properly to insure proper compressor rotation. Improper phasing may result in compressor damage. An electronic phase sequence indicator must be used to check supply-wiring phase. Also, the “Wild” leg of the three-phase power must be connected to the middle leg on the contactor. When supplying power to external water pumps with the heat pump’s power supply, use only impedance protected motors. An ECONAR PumpPAK can be wired directly to the contactor and grounded in the grounding lug. A pump relay and a terminal block (BP) are supplied in the electrical box for the hydronic side pump. The relay will start the pump with a call from the aquastat or thermostat. The pump relay is activated by power to Y on the terminal strip of hydronic units (wire Y to X). The use of impedance protected pumps eliminates the need for additional fusing. Do not connect more than a 1/3 horsepower pump to the internal pump relay. If larger pumps are required, a separate power supply is required to supply the pump. To start this pump use a 24-volt relay pulled in from the Y and X terminals.

VIII. 24 VOLT CONTROL CIRCUIT The wiring diagram in Figure 7 shows the low voltage controls of the heat pump and some generic external control schemes. This section will break down the three basic components of the low voltage circuit; transformer, thermostat/aquastat, and controller. A. Transformer Electrical diagrams are provided in Figure 7, and also on the electrical box cover panel of the heat pump. An internal 24-volt, 55 VA transformer is provided to operate

all control features of the heat pump. Even though the 55 VA transformer is larger than the industry standard 40 VA transformer, it can still be overloaded quickly when using it for control equipment like zone valves or fan coil relays. Table 4 shows the transformer usage for the hydronic heat pumps. Table 4 – Transformer Usage (VA)

Component 37-57 Contactor 7 Pump Relay 3 Reversing Valve 4 Controller 1 Thermostat 1 Total 16 VA Available 39 VA

If the system’s external controls require more than the VA available for external use from the transformer, an external transformer must be used. You can see that in Figure 5, the heat pump’s internal transformer can easily power the external 24-Volt system. In contrast, Figure 4 shows a fan coil system with its own power supply, which must be coupled to the heat pump to put the heat pump into the cooling mode. This can be accomplished using an isolation relay, which isolates the fan coil power supply from the heat pump's transformer (e.g. use the fan coils independent power supply to energize the coil of a relay, passing a signal across the N.O. contacts from the heat pump's transformer). The heat pump's transformer can generally power simpler control systems consisting of a few relays or zone valves (depending, of course, on the VA draw of the components). On more complicated control systems the transformers capacity is used up very quickly.

Note: For units operating on 208V electrical service, the transformer must be switched to the correct lead (see electrical diagram – Figure 7). Units are factory shipped with the transformer set for 240V service. Operating a unit on 208V with the transformer set to 240V will cause the unit to operate with lower than normal control voltage. B. Thermostat/Aquastat Consult the instructions in the thermostat box for proper mounting and thermostat operation.

CAUTION- miswiring of control voltage on system controls can result in transformer burnout.

Note: If a single thermostat controls multiple heat pumps, the control wiring of the heat pumps must be isolated from each other. This will prevent the heat pumps from receiving high voltage through the common wiring if it is turned off at the circuit breaker for service.

14

Power is supplied to the thermostat by connecting the R and X terminals to the heat pump terminal strip. The Y terminal energizes the compressor. The unit is put into the cooling mode when the thermostat energizes the O terminal, which operates the 4-way reversing valve. The L terminal is used to power the lockout LED on a thermostat, which indicates a compressor lockout. The pump relay is connected to the circulation pump's 3 pole, high voltage terminal block (BP). The hydronic side circulation pump receives power from BP, which is energized by the pump relay. A simple, single stage heating aquastat on a storage tank or wall mounted thermostat may be all that is required for simple heat only systems. This aquastat closes and passes power to the Y terminal, energizing the compressor and circulation pumps in the heating mode. When mounting an aquastat inside a storage tank, always use a submersible type aquastat. The aquastat should be installed approximately 1/3 of the way down into the tank. Set the aquastat differential to 15oF to avoid short cycling A cooling aquastat can be mounted on the water supply line, as shown in Figure 4. This aquastat acts as a low limit, which shuts the heat pump down when the cooling water reaches a minimum (e.g. 35oF). Changeover from heating to cooling can be achieved in two ways:

1) A manual toggle switch to select the control aquastat (heating or cooling) 2) A cooling thermostat which powers the coil of a

single pole/double throw relay which selects the heating aquastat (normally closed contact) or cooling aquastat (normally open contact) shown in Figure 4.

Note: Always wire the system to shut down (Anti-

short-cycle) between a heating and cooling mode changeover. Nuisance trip-outs could occur from changing modes “on the fly”. Any number or types of thermostats, aquastats, or switches can be used with an independent power supply (typically a 24-volt transformer) to activate specific zone controls. These zone controls are normally either a zone pump (Figure 4) or zone valves (Figures 3 and 6). End switches on the zone valves can be used to pass a signal to a pump relay when the zone valve is open. The pump relay then activates a common pump, which supplies any number of zones. Example: the fan coil in Figure 4 could be supplied by the same pump as the radiant floor system if zone valves were used instead of two pumps.

Note: A common maximum aquastat setpoint is 100oF (with a 15oF differential). The tank will then shut down when it reaches 100oF, however, the leaving water temperature from the heat pump is actually 115oF (the

maximum design temperature). The aquastat maximum setpoint should limit the head pressure of the heat pump to 500 psi. If a thermostat is equipped with an anticipator it should be set to its maximum setting to avoid interfering with heat pump operation. The anticipator is a resistor in the thermostat that heats up as current is drawn through and satisfies the thermostat prematurely. This reduces system capacity by restricting run time. C. Controller The controller receives a signal from the thermostat and initiates the correct sequence of operations for the heat pump. The controller performs the following functions:

1) Earth Loop Pump Initiation 2) Compressor Operation 3) 4-Way Valve Control 4) Compressor Lockouts 5) Compressor Anti-Short-Cycle 6) System Diagnostics

1. Earth Loop Pump Initiation If a PumpPAK is used, it should be wired directly to the contactor of the compressor. If a PumpPAK is not used, a separate pump can be used which is energized with a pump relay (Note: electrical code will require a fused disconnect for pumps other than PumpPAKs). When there is a call for an M1 output from the controller, the contactor will energize, starting the compressor and earth loop pump. 2. Compressor Operation A Y signal from the thermostat will ask the controller to initiate heating or cooling. The controller then decides, based on lockout and anti-short-cycle periods, when to bring the compressor on. The M1 output of the controller energizes the compressor. This compressor stays on until on the thermostat is satisfied. 3. 4-Way Valve Control The controller energizes the 4-way reversing valve to direct the flow of refrigerant. When the thermostat calls for cooling on the O terminal, the controller energizes its O output to send control power to the reversing valve (VR), to switch the refrigerant circuit to the cooling mode. 4. Compressor Lockouts A compressor lockout occurs if the high-pressure, low pressure, or freeze protection pressure switches open. The controller blocks the signal from the thermostat to the contactor that normally would energize the compressor. In the event of a compressor lockout the controller will send a signal from L on the terminal strip to an LED on the thermostat to indicate a lockout condition. This lockout condition means that the unit has shut itself down to

15

protect itself, and will not come back on until power has been disconnected (via the circuit breaker) to the heat pump for one minute. Problems that could cause a lockout situation include: 1. Water flow or temperature problems 2. Internal heat pump operation problems 3. Cold ambient air temperature conditions

If a lockout condition exists, the heat pump should not be reset more than once; a service technician should be called immediately.

The cause of the lockout must be determined. Repeated reset may cause damage to the system. 5. Compressor Anti-Short-Cycle An anti-short-cycle is a delay period between the time a compressor shuts down and when it is allowed to come on again. This protects the compressor and avoids nuisance lockout conditions. Anti-short-cycles occur after these two conditions;

1. A 30 second to one minute time-out period occurs on the compressor before it will start after its last shutdown.

2. A 4 minute 35 second delay is incorporated into the timing function immediately after power is applied to the heat pump. This occurs only after reapplying power to the unit. To avoid this timeout while servicing the unit, apply power, disconnect and reapply power very quickly. This can sometimes eliminate the waiting period.

6. System Diagnostics The controller is equipped with diagnostic LED lights, which indicate the system status at any particular time. The lights indicate the following conditions: 1. 24 Volt system power GREEN 2. Fault or Lockout YELLOW 3. Anti-short-cycle mode RED

IX. STARTUP Before applying power to the heat pump, check the following items: - Water supply plumbing to the heat pump is

completed and operating. Manually open the water valve on well systems to check flow. Make sure all valves are open and air has been purged from a loop system. Never operate the system without correct water supply.

- Low voltage wiring of the thermostat and any additional control wiring is complete. Set thermostat to the “OFF” position.

- All high voltage wiring is correct including fuses, breakers, and wire sizes.

- The heat pump is located in a warm area (above 45oF). Starting the system with low ambient temperature conditions is more difficult; do not

leave the area until the space is brought up to operating temperatures.

- Hydronic side water temperatures are warm enough (50oF or above) to start in the heating mode.

- The hydronic side water flow rate is correct (shown in Table 1). Low water temperature starting may require flow reduction until the system is up to operating temperature.

You may now apply power to the unit. A 4 minute 35 second delay on power up is programmed into the heat pump before the compressor will operate. During this time the pump relay will energize the hydronic side-circulating pump. Verify that the flow rate and temperature of the hydronic side flow are at the recommended levels. The following steps will assure that your system is heating and cooling properly. After the initial time-out period is completed, the red indicator light on the controller will shut off. The heat pump is now ready for operation. - Turn the thermostat up to its highest temperature

setting. Place the thermostat to the "HEAT" position. The compressor should start 1 to 2 seconds later. If an electronic thermostat is used it may cause its own compressor delay at this time, but the compressor will come on after the time-out period.

- After the unit has run for 5 minutes, check the hydronic side return and supply water temperatures. A water temperature rise of 10oF to 15oF is normal in the heating mode, but variations in water temperature and water flow rate can cause variations outside the normal range.

- Turn the thermostat to the “OFF” position. The compressor will shut down in 1 to 2 seconds.

- Next, turn the thermostat down to its lowest setting. Place the thermostat in the "COOL" position. The compressor will start after an anti-short-cycle period of 2 to 3 minutes from its last shutdown. The anti-short-cycle period is indicated by the red light on the controller.

- After the unit has run for 5 minutes, check the hydronic side return and supply water temperatures. A water temperature drop of 10oF to 15oF is normal in the cooling mode but factors mentioned in the heating section can also effect temperature drop.

- Set the thermostat for normal operation. - Instruct the owner on correct operation of the

thermostat and heat pump system. The unit is now operational.

The heat pump is equipped with both high and low pressure switches that shut the unit off if the refrigerant pressure exceeds 580 psi or goes below 50 psi. If the system exceeds 580 psi, the high-pressure switch will trip and lock the unit off until power has been disconnected at

16

the circuit breaker for approximately one minute. System pressures below 50 psi will trip the low pressure switch and lock the unit out until the power supply has been de-energized for one minute. On a well water system, the freeze protection switch (field installed part number 30-2020) will activate the lockout at 65 psi in the heating mode to protect the water coil against freeze rupture. After resetting a lockout (by disconnecting power to the unit) verify that water flow is at the recommended levels before energizing the compressor. DO NOT reset a well water system without verifying water flow. DO NOT reset the system more than once.

Repeated resetting of the lockout can cause serious damage if the reason for lockout is not corrected.

- If lockout occurs more than once contact your ECONAR dealer immediately.

X. SERVICE Regular service to a GeoSource Ultra hydronic heat pump is very limited. Setting up regular service checkups with your ECONAR dealer could be considered. Any major problems with the heat pump system operation will be indicated on the thermostat lockout light. A. Lockout Lights A lockout light on the thermostat will light to indicate major system problems. If lockout occurs, follow the procedure below: 1) Check for correct water supply from the earth loop or

well water system. 2) Reset the system by disconnecting power at the

circuit breaker for one minute and then reapplying power.

3) If shutdown reoccurs, check the indicator lights on the controller in the unit and review the lockout troubleshooting guide in section XI of this manual.

4) If lockouts persist, call your ECONAR dealer. Do not continuously reset the lockout condition or damage may occur.

XI. THERMOSTAT OPERATION

This section covers basic operation of the standard 2-heat 1-cool thermostat that ECONAR carries. This thermostat is ECONAR part number 70-2002, Honeywell part number T8511G. If your thermostat is a different style, please refer to the instructions supplied with that thermostat. The settings of the thermostat are controlled with the “System”, “Fan”, “i”, up key, and down key buttons. The System and Fan buttons are located behind the flip-down panel. By pressing the “System” button, you can control the mode that the thermostat operates in. The five system settings are:

1. Em. Heat – Controls backup heating. In this mode, the heat pump’s compressor is locked out, and only the backup heating elements (if installed) operate.

2. Heat – Controls normal heating operation. 3. Off – Both heating and cooling are off. 4. Cool – Controls normal cooling operation. 5. Auto – The thermostat automatically changes

between heating and cooling operation, depending on the indoor temperature.

Note: When the thermostat is set to Auto, there must be at least a 2oF difference between the Heating setpoint temperature and the Cooling setpoint temperature. The “Fan” button controls the operation of the heat pump’s blower. The Fan button has two settings:

1. On – The blower operates continuously. 2. Auto – The blower operates with either a heating or

cooling call. By pressing the “i”, or information, key, you can cycle through your temperature setpoints. If you wish to change a temperature setting, press either the up key or down key when the appropriate mode is displayed. For example, you wish to change the heating setpoint from 68oF to 70oF. Push the “i” key until the heating setpoint appears on the LCD display. Then, press the up key until the desired setpoint is reached. The thermostat will automatically switch back to the room temperature display after a few seconds. If the LED on the bottom of the thermostat is lit, your heat pump has locked itself out to protect itself. If this occurs, please see the Compressor Lockout section of this manual. If you have additional questions about your thermostat, please see the installation manual that was sent with the thermostat.

XII. TROUBLESHOOTING GUIDE FOR LOCKOUT CONDITIONS If the heat pump goes into lockout on a high or low pressure switch, the cause of the lockout can be narrowed down by knowing the operating mode and which pressure switch the unit locked out on. The following table will help track down the problem once this information is known. Note: A lockout condition is a result of the heat pump shutting itself off to protect itself, never bypass the lockout circuit. Serious damage can be caused by the system operating without lockout protection.

MODE LOCKOUT CONDITION POSSIBLE CAUSE High Pressure

(Condenser/Hydronic Side) -Loss/lack of flow through hydronic heat exchanger -High fluid temperature operation in the hydronic loop

-Overcharged refrigerant circuit Heating Low Pressure (Evaporator/Earth Coupled Side)

-Loss/lack of flow through earth coupled coil -Low fluid temperature operation in the earth loop -Freezing fluid in heat exchanger (lack of antifreeze) -Undercharged/overcharged refrigerant circuit -Expansion valve/sensing bulb malfunction

High Pressure (Condenser/Earth Coupled Side)

-Loss/lack of flow in earth loop -High fluid temperature operation in the earth loop -Dirty (fouled) condenser coil

-Overcharged refrigerant circuit Cooling Low Pressure (Anti-Short Cycle) (Evaporator/Hydronic Side)

-Loss/lack of flow through hydronic heat exchanger -Low fluid temperature operation in the hydronic loop -Freezing fluid in hydronic heat exchanger (lack of antifreeze) -Undercharged/overcharged refrigerant circuit -Expansion valve/sensing bulb malfunction

XIII. TROUBLESHOOTING GUIDE FOR UNIT OPERATION

PROBLEM POSSIBLE CAUSE CHECKS AND CORRECTIONS Blown Fuse/Tripped Circuit Breaker

Replace fuse or reset circuit breaker. (Check for correct size fuse or circuit breaker.)

Blown Fuse on Controller Replace fuse on controller. (Check for correct size fuse.) Broken or Loose Wires Replace or tighten the wires. Voltage Supply Low If voltage is below minimum voltage on data plate, contact local power company. Low Voltage Circuit Check 24-volt transformer for burnout or voltage less than 18 volts. Thermostat Set thermostat on "Cool" and lowest temperature setting, unit should run. Set

thermostat on "Heat" and highest temperature setting, unit should run. If unit does not run in both cases, the thermostat could be wired incorrectly or be faulty. To prove faulty or miswired thermostat, disconnect thermostat wires at the unit and jumper between "R" and "Y" terminals and unit should run. Replace thermostat with correct thermostat only. A substitute may not work properly.

Entire unit does not run.

Interruptible Power Check incoming supply voltage. Water Lack of sufficient pressure, temperature and/or quantity of water. Unit Undersized Recalculate heat gains or losses for space to be conditioned. If excessive, rectify

by adding insulation, shading, etc. Loss of Conditioned Air by Leaks Check for leaks in ductwork or introduction of ambient air through doors and

windows. Thermostat Improperly located thermostat (e.g. near kitchen sensing inaccurately the comfort

level in living areas). Check anticipator setting (Should be 1.0 or 1.2). Insufficient cooling or

heating Airflow (Across fan coil) Lack of adequate airflow or improper distribution of air. Check the motor speed

and duct sizing. Check the filter, it should be inspected every month and changed if dirty. Remove or add resistance accordingly.

Refrigerant Charge Low on refrigerant charge causing inefficient operation. Adjust only after checking CFM and GPM.

Compressor Check for defective compressor. If discharge pressure is too low and suction pressure too high, compressor is not pumping properly. Replace compressor.

Reversing Valve Defective reversing valve creating bypass of refrigerant from discharge to suction side of compressor. When it is necessary to replace the reversing valve, wrap it with a wet cloth and direct the heat away. Excessive heat can damage the valve.

Desuperheater The desuperheater circuit (in-line fuse) should be disconnected during cold weather to allow full heating load to house.

PROBLEMS POSSIBLE CAUSE CHECKS AND CORRECTIONS Thermostat Check setting, calibration, and wiring, if thermostat has an anticipator, set it at 1.0

or 1.2. Wiring Check for loose or broken wires at compressor, capacitor, or contactor. Blown Fuse Replace fuse or reset circuit breaker. (Check for correct size fuse or circuit

breaker.) High or Low Pressure Controls The unit could be off on the high or low-pressure cutout control. Check water

GPM, ambient temperature and loss of refrigerant. If the unit still fails to run, check for faulty pressure controls individually. Replace if defective.

Defective Capacitor Check capacitor, if defective remove, replace, and rewire correctly. Voltage Supply Low If voltage is below minimum voltage specified on the data plate, contact local

power company. Check voltage at compressor for possible open terminal. Low Voltage Circuit Check 24-volt transformer for burn out or voltage less that 18 volts. With a

voltmeter, check signal from thermostat at Y to X, M1 on controller to X, capacitor voltage drop. Replace component that does not energize.

Compressor Overload Open In all cases an "internal" compressor overload is used. If the compressor motor is too hot, the overload will not reset until the compressor cools down. If the compressor is cool and the overload does not reset, there may be a defective or open overload. Replace the compressor.

Compressor Motor Grounded Internal winding grounded to the compressor shell. Replace the compressor. If compressor burnout replace the liquid line filter/drier.

Compressor Windings Open Check continuity of the compressor windings with an ohmmeter. If the windings are open, replace the compressor.

Hydronic pump runs but compressor does not, or compressor

short cycles.

Seized Compressor Try an auxiliary capacitor in parallel with the run capacitor momentarily. If the compressor still does not start, replace it.

Thermostat Improperly located thermostat (e.g. near kitchen, sensing inaccurately the comfort level in living areas). Check anticipator setting. Should be 1.0 or 1.2.

Unit short cycles Compressor Overload Defective compressor overload, check and replace if necessary. If the compressor runs too hot, it may be due to a insufficient refrigerant charge.

Aquastat The differential is set to close on aquastat. Increase differential setting to 15oF. Wiring and Controls Loose wiring connections, or control contactor defective. Thermostat Improperly Set Is it below room temperature? Check the thermostat setting.

Unit will not Defective Thermostat Check thermostat operation. Replace if found defective. operate in Incorrect Wiring Check for broken, loose, or incorrect wires. "heating" Aquastat set Too High Heat pump is trying to heat hot water to too hot of a temperature (over 120oF).

Reduce aquastat setpoint. Reversing Valve does not Shift Defective solenoid valve will not energize. Replace solenoid coil.

Reversing Valve does not Shift, the Valve is Stuck

The solenoid valve is de-energized due to miswiring at the unit or thermostat-correct wiring. Replace if valve is tight or frozen and will not move. Switch from heating to cooling a few times to loosen valve.

Aquastat set Too Low Heat pump is trying to cool water too low. Increase aquastat setpoint.

Unit does not cool (Heats Only)

Insufficient Antifreeze Water is freezing in hydronic coil. Check antifreeze level and add antifreeze to obtain correct freeze protection.

Compressor Make sure the compressor is not in direct contact with the base or sides of the cabinet. Cold surroundings can cause liquid slugging, increase ambient temperature.

Contactor A "clattering" or "humming" noise in the contactor could be due to control voltage less than 18 volts. Check for low supply voltage, low transformer output or extra long runs of thermostat wires. If the contactor contacts are pitted or corroded or coil is defective, repair or replace.

Rattles and Vibrations Check for loose screws, panels, or internal components. Tighten and secure. Copper piping could be hitting the metal surfaces. Carefully readjust by bending slightly.

Water and Airborne Noises Undersized ductwork will cause high airflow velocities and noisy operation. Excessive water through the water-cooled heat exchanger will cause a squealing sound. Check the water flow ensuring adequate flow for good operation but eliminating the noise.

Noisy Operation

Cavitating Pumps Purge air from closed loop system.

Instructions, Assumptions, and Additional Notes A) Enter the appropriate pool dimensions where requested on lines 1, 2, and 3. If the pool depth is not constant,

please enter the overall average depth. If the pool is not rectangular in shape, please move on to the next step. B) Calculate lines 4, 5, and 6 after lines 1-3 are filled in. There are 7.48 Gal Water per Cu. Ft. If the pool is not

rectangular in shape, such as elliptical, oval, & kidney shapes, manually calculate the information needed for lines 4 and 5 and enter the results in the appropriate boxes where requested on these lines.

C) Line 7: There are 62.42 Lb. Water per Cu. Ft., and 8.34 Lb. Water per U.S. Gallon. D) Enter the desired pool temperature in both boxes on line 8. If this temperature is not known, 80oF is a good

default to use. E) Enter the initial pool water temperature in the box on line 9. Generally, this will not be any colder than average

well water temperature (approximately 50oF.) F) Enter the average ambient outdoor air temperature for the coldest month that the swimming pool will be in use

in the box on line 10. G) Line 13: Use the following equation to calculate the initial BTU's required to heat the pool without any

consideration to time or to surface heat loss via convection. Initial BTU's = 1.0 [BTU/LB*oF] x Line 7 x Line 11

H) Line 14: Enter the amount of time in hours that will be allowed to initially heat the pool. (4 to 5 days [120 hours] is normally acceptable and economical for private pools.)

I) Line 15: Calculates the heating capacity (BTU/hr) required to initially heat the pool. Heating Capacity [BTU/hr] = Line 13 / Line 14

J) Line 16: Enter the average wind speed correction factor as listed below. (typically 3-5 MPH) (<3 MPH = .75, 3 to 5 MPH = 1.0, 5 to 10 MPH = 1.25, >10 MPH = 2)

K) Line 17: Calculate the BTU/hr heat loss from the surface of the pool due to convection. Convection Losses [BTU/hr] = 10.5 [BTU/hr*Sq Ft*oF] x Line 4 x Line 12 x Line 16 The greatest heat loss (typically 50-60%) in a swimming pool is through evaporation. Radiation and evaporative losses can be reduced 50% through the use of a pool cover. Solar gains in unshaded pools can add up to 100,000 BTU/hr which offsets some convective loss. Because of these solar gains and economic reasons, total heating capacity for only one half of the convective losses are required when sizing. Heat loss by conduction through pool is minimal in an in-ground pool. Conduction losses for above ground pools can be compensated for by the average wind speed correction factor.

XV. DESUPERHEATER (OPTIONAL) A GeoSource Ultra unit equipped with a desuperheater can provide supplemental heating of a home's domestic hot water. This is done by stripping heat from the superheated gas leaving the compressor and transferring it to a hot water tank. A desuperheater pump, manufactured into the unit, circulates water from the domestic hot water tank, heats it using a double walled water-to-refrigerant heat exchanger, and returns it to the tank. The desuperheater provides supplemental heating because it only heats water when the compressor is already running to heat or cool the conditioned space. Because the desuperheater is stripping some of the energy from the heat pump in order to heat the water, the heat pump’s capacity in the winter will be slightly less than a unit without a desuperheater. During extremely cold weather, or if the heat pump cannot keep up with heating the space, the desuperheater fuse may be pulled in order to get more capacity out of the unit. Insulated copper tubing should be used to run from the hot water tank to the desuperheater connections on the left side of the unit. The built in desuperheater pump can provide the proper flow to the desuperheater if the total equivalent length of straight pipe and connections is kept to a maximum of 90 feet of 1/2-inch type L copper tubing. This tubing can be connected to the hot water tank in two ways: METHOD 1 Using a desuperheater tee installed in the drain at the bottom of the water heater (See Figure 9). This is the preferred method for ease of installation, comfort and efficiency. The tee eliminates the need to tap into the domestic hot water lines and eliminates household water supply temperature variations that could occur from connecting to the hot water pipes. METHOD 2 Taking hot water from the bottom drain and returning it to the cold water supply line (See Figure 10). This method maintains the same comfort and efficiency levels but increases installation time and costs. This method requires a check valve in the return line to the cold water supply to prevent water from flowing backwards through the desuperheater when the tank is filling. Water passing through the pump backwards damages the rotor's bearing,

which reduces pump life and causes noise problems in the pump. A spring-type check valve with a pressure rating of 1/2 psi or less is recommended. All air must be purged from the desuperheater plumbing before the pump is engaged. To purge small amounts of air from the lines, loosen the desuperheater pump from its housing by turning the brass collar. Let water drip out of the housing until flow is established, and re-tighten the brass collar. Using 1/2-inch copper tubing from the tank to the desuperheater inlet is recommended to keep water velocities high, avoiding air pockets at the pump inlet. An air vent in the inlet line can also help systems where air is a problem. If one is used (we recommend a Watts Regulator brand FV-4 or Spirovent) mount it near the desuperheater inlet roughly 2-1/2 inches above the horizontal pipe. Shutoff valves allow access to the desuperheater plumbing without draining the hot water tank. Keep valves open when pump is running.

CAUTION: Running the desuperheater pump without water flow will damage the pump. Poor water quality may restrict the effectiveness of using the desuperheater tee by plugging the entrance with scale or buildup from the bottom of the tank, restricting water flow. Desuperheater maintenance includes periodically opening the drain on the hot water tank to remove deposits. If hard water, scale, or buildup causes regular problems in hot water tanks in your area, it may result in a loss of desuperheater effectiveness. This may require periodic cleaning with Iron Out or similar products. The desuperheater's high temperature cutout switch is located on the return line from the water heater. The switch is wired in series with the desuperheater pump to disable the pump from circulating at entering water temperature above 140oF. If the desuperheater causes tank temperatures to become uncomfortably hot, this temperature switch can be moved to the leaving water line which will reduce the tank maximum temperatures 10oF to 15oF. Do not remove the high temperature switch or tank temperatures could become dangerously high. A fuse is attached to the fuseholder and must be inserted in the fuseholder after the desuperheater is operational. Do not insert fuse until water flow is available or the pump may be damaged. Remove the fuse to disable the pump if the desuperheater isn’t in operation.

1. Safety warning

1.1 Read this booklet

This booklet is designed to help a certified installer install, begin operation of and troubleshoot the Grundfos VersaFlo UP pumps. The booklet should be left with the owner of the pump for future refer-ence and information regarding its operation. Should the owner experience any problems with the pump, a certified professional should be contacted.

1.2 Electrical work

All electrical work should be performed by a qualified electrician in accordance with the latest edition of the National Electrical Code, local codes and regula-tions.

2. Pre-installation checklist

2.1 Confirm you have the correct pump

• Read the pump nameplate to make sure it is the one you ordered.

• Compare the pump's nameplate data and its per-formance curve (for head, GPM, etc.) with the application in which you plan to install it.

• Will the pump do what you expect it to do?

2.2 Check the condition of the pump

The shipping carton your pump came in is specially designed around your pump during production to prevent damage.

As a precaution, it should remain in the carton until you are ready to install it. At that point, look at the pump and examine it for any damage that may have occurred during shipping.

Examine any other parts of the shipment as well for any visible damage.

2.3 Verify electrical requirements

Verification of the electrical supply should be made to be certain the voltage, phase and frequency match that of the pump motor. The proper operating voltage and other electrical information can be found on the pump nameplate.

These motors are designed to run on ±10% of the nameplate-rated voltage.

Wiring connection diagrams can be found inside the terminal box cover and later in these Installation and Operating Instructions. If voltage variations are larger than ±10%, do not operate the pump.

WARNING!A faulty motor or wiring can cause electri-cal shock that could be fatal, whether touched directly or conducted through standing water. For this reason, proper grounding of the pump to the power sup-ply's grounding terminal is required for safe installation and operation.

In all installations, the above-ground metal plumbing should be connected to the power supply ground as described in Article 250-80 of the National Electrical Code.

2.4 Pumped liquid requirements

CAUTION: The VersaFlo UP pump is intended for use with water only.

The pump can be used to circulate:

• Potable hot water

• Water for hydronic heating

• Cooling water

• In domestic hot-water systems it is advisable to use bronze pumps (VersaFlo UP or UPS model) only for water with a degree of hardness lower than 14 grains per gallon of hardness. For water with a higher degree of hardness, a direct-coupled VersaFlo TP pump is recommended.

• If the pump is installed in a heating system, the water should meet the requirements of accepted standards on water quality in heating systems.

The pump is lubricated and cooled by the liquid being pumped. Therefore, the pumped liquid must always be allowed to circulate through the pump. Extended periods without circulation will cause pre-mature wear to the bearings and excessive motor heat. The pumped liquid must also meet the follow-ing requirements:

Minimum pump inlet pressure (during operation)

Liquid temperature range

Continuously: 14°F (–10°C) up to 230°F (110°C).

Intermittent: < 284°F (140°C) for short periods of time.

Domestic hot water: <140°F (60°C).

3. Installation procedures

3.1 Electrical preparation

Terminal box position

At the bottom of the stator, closest to the pump hous-ing, there are eight drain holes to allow condensed water to escape. The drain holes shall not be blocked. The drain holes must point downwards. The terminal box must therefore point upwards in one of the positions shown in fig. 1. The following terminal box positions apply whether the piping is mounted vertically or horizontally.

Fig. 1 Possible terminal box positions

Rotating the terminal box

To rotate the terminal box, follow these steps:

1. Remove the four allen-head screws holding the pump head onto the pump housing.

2. Carefully lift the pump head and rotate it so the terminal box is in the desired position. DO NOT locate the terminal box beneath the pump. Make sure the O-ring is properly seated in the pump housing.

3. Replace the pump head onto the pump housing.

4. Tighten the allen-head screws evenly.Torque to:8 mm............15 ft lbs10 mm..........25 ft lbs.

5. Check to make sure the rotor turns freely. Do this by removing the vent plug in the middle of the pump nameplate. Insert a medium size flat-blade screwdriver into the slot at the exposed end of the shaft. Gently turn the shaft. If it does not turn easily, repeat steps 1 to 4 above.

6. The position of the nameplate can be changed by easing the outer edge of the plate at the cutout with a screwdriver. Turn the nameplate to the required position and push into place.

7. Refer to pages 11 and 12 for additional instruc-tions.

3.2 Piping considerations

Thoroughly clean and flush all dirt and sediment from the system before attempting to install the pump.

Location in the piping line

The pump should never be located at the lowest point of the piping system, where dirt and sediment collect. Nor should it be located at the highest point of the piping system, where air accumulates.

Mounting positions

The arrows on the flanges of the pump indicate the direction of water flow. Although the VersaFlo UP may be installed in either vertical or horizontal pip-ing, the motor shaft must always remain horizontal, as shown in figures 1 and 2.

Fig. 2 Direction of water flow through the pump

NOTE: Pumps installed outdoors must be protected by a ventilated, watertight cover to keep out moisture and dirt.

3.3 Connect the pump

Install the pump into the piping system.

Grundfos recommends that pressure gauges be installed in the inlet and discharge flanges or pipes to check pump and system performance.

3.4 Electrical connection

The electrical connection and protection should be carried out in accordance with the latest edition of the National Electrical Code, local codes and regula-tions by a qualified electrician.

The operating voltage and frequency are marked on the pump nameplate. Make sure that the motor is suitable for the electrical supply it is being installed to.

The pump should be grounded to protect against indirect contact and a ground fault interrupter can be used as extra protection.

Dual-voltage pump (single-phase)

All single-phase pumps are equipped with built-in, automatic resetting, thermal overload protection. The pump is protected at both 115 V and 230 V. The pump may also be protected by using an exter-nal contactor or motor starter.If the pump is protected by means of a motor starter, the starter must be set to the current consumption of the pump. The current consumption is stated on the pump nameplate.

Figures 4 and 6 show the possible connections.

WARNING!The pump must be positioned so that someone cannot accidentally come into contact with the hot surfaces of the pump.


The pump must be grounded.

The pump must be connected to an exter-nal main power switch.

All VersaFlo UP pumps (fig. 3 and fig. 5) come with a dual-voltage terminal box. The voltage is changed by the orientation of the jumpers as shown on page 8. All pumps are equipped with an internal automatic resetting thermal overload switch (terminals P1 and P2).

4. Starting the pump

4.1 Vent the piping system

After the pump has been installed and the electrical connections made, the piping system must be vented.

CAUTION: Never operate the pump dry - the system must first be filled with liquid and vented.

NOTE: Do not vent the piping system through the pump.

Instead, follow these steps:

1. Fill and pressurize the system with liquid, and vent all trapped air from the piping by suitable means.

2. If any isolation valves are used, make sure they are OPEN.

4.2 Voltage selection

Change the pump input voltage as follows:

The voltage is changed by the position of the jump-ers in the terminals. The jumpers are fitted according to:

• figure 7 for 115 V AC

• figure 8 for 230 V AC.

5. Troubleshooting

5.1 Fault finding chart

WARNING!Before removing the terminal box cover, make sure that the electrical supply has been switched off and that it cannot be accidentally switched on.

The pumped liquid may be scalding hot and under high pressure. Before any removal or dismantling of the pump, the system must be drained or the isolation valves on both sides of the pump must be closed.

Fault Cause Remedy

1. The pump does not run. a) One fuse in the installation is blown.

Replace the fuse.

b) External circuit breaker is switched off.

Switch the circuit breaker on.

c) Current-/voltage-operated ground fault interrupter has tripped.

Repair the insulation defects and reset the interrupter.

d) The pump has been cut out by the thermal overload switch due to high liquid temperature or blocked rotor.

Check that the liquid temperature falls within the specified range. The pump will restart automatically when it has cooled to normal temperature.

e) Rotor blocked, but the pump hasn't been cut out by the thermal overload switch.

Switch off the electrical supply and clean/repair the pump.

2. Noise in the system. a) Air in the system. Vent the system.

b) The pump flow is too high. Reduce the pump performance.

c) The pressure is too high. Reduce the pump performance.

3. Noise in the pump. a) Air in the pump. Vent the pump.

b) The inlet pressure is too low.

Increase the inlet pressure and/or check the air volume in the expansion tank (if installed).

4. Insufficient heat in some places in the heating system.

a) The pump performance is too low.

Increase the pump performance, if possible, or replace the pump with a pump with higher flow.

5.2 Preliminary checks

Supply voltage

To check the voltage being supplied to the motor, use a voltmeter.

Single-phase motors

Touch one voltmeter lead to each of the lines supply-ing power to the pump, L and N.

Fig. 10 Checking single-phase power

Evaluation

When the motor is under load, the voltage should be within 10% (+ or –) of the nameplate voltage. Any variation larger than this may indicate a poor electri-cal supply and can cause damage to the motor wind-ings. The motor should not be operated under these conditions. Contact your power supplier to correct the problem or change the motor to one requiring the voltage you are receiving.

5.3 Current measurement

To check the current, use an ammeter.

To do so, follow these steps:

1. Make sure the pump is operating.

2. Set the ammeter to the proper scale.

3. Place the tongs of the ammeter around the leg to be measured.

4. Compare the results with the amp draw informa-tion on the motor nameplate.

Evaluation

If the current draw exceeds the listed nameplate amps, then check the following:

• The voltage supplied to the pump may be too high or too low.

• The contacts on the motor starter may be burned.

• The terminals in the starter or terminal box may be loose.

• There may be a winding defect. Check the wind-ing and insulation resistance.

• The motor windings may be shorted or grounded.

• The pump may be damaged in some way and may be causing a motor overload.

• A voltage supply or balance problem may exist.

Fig. 11 Current measurement

5.4 Insulation resistance (lead-to-ground)

To check the insulation resistance (lead-to-ground) of the motor and leads, a megohmmeter is required.


1. Turn the POWER OFF.

2. Disconnect all electrical leads to the motor.

3. Set the scale selector on the megohmmeter to R x 100K, touch its leads together, and adjust the indicator to zero.

4. Touch the leads of the megohmmeter individually to each of the motor leads and to ground (i.e. L to ground; N to ground, etc.).

WARNING!Be careful, since power is still being sup-plied to the pump. Do not touch the volt-meter leads together while they are in con-tact with the power lines.

Fig. 12 Insulation resistance measurement

Evaluation

The resistance values for new motors must exceed 1,000,000 ohms. If they do not, replace the motor.

5.5 Winding resistance (line-to-line)

To check the winding resistance of the motor wind-ings, a megohmmeter is required.


1. Turn the POWER OFF.

2. Disconnect all electrical leads to the motor.

3. Set the scale selector on the megohmmeter to R x 1, touch its leads together and adjust the indicator to zero.

4. Using the following chart for reference, touch the leads of the megohmmeter to the appropriate pair of connectors. Check all pairs that are present and write down and label (RA1, RA2, RS) all readings.

5. Compare your readings to the matching model, phase and voltage on the chart in section 5.6.

Evaluation

The resistance values must fall within the tolerances listed in section 5.6. If they do not, replace the motor.

FUNCTION 5. TEMPERATURE SETTING - Press “▲” to increase set temperature. - Press “▼” to decrease set temperature. - Press “▲” and “▼” Simultaneously to toggle between °C and °F display mode. - Temperature range: 16°C to 30°C in °C display mode and 60°F to 86°F in °F display mode.

6. DELAY TIMER SETTING - The delay timer is capable of delaying both on and off functions. The delay feature will take affect in all modes with the exception of the sleep mode. Each time the “▲” and “▼” is pressed it increases or decreases the On or OFF set point by 1 hour; up to a maximum of 18 hours. To set the OFF DELAY: -With the system in operation, enter the system OFF time by pressing the “▲” button to the desired number of hours ahead that the system will be allowed to run. When the number of hours entered has elapsed the system will turn off. To set the ON DELAY: - Set the on delay by entering the desired mode of operation (fan, heat, cool and the appropriate temperature. This will be the settings the system will follow when operation resumes. After setting the mode and any applicable temperature with the control, turn the remote off. Now enter the number of hours to elapse before operation resumes by pressing the “▲” button on the remote to the desired number. When the time (in hours) entered has elapsed, the system will resume operation according to the pre-set mode and temperature.

2. To set the louver swing (continuous motion). The sequence is as follows.

9. SLEEP - This function when selected will allow the user to determine a “sleep” period. In cooling the selected temperature will rise to 1° above set point in 1/2 hour, rising to 2° in 1 hour, rising again to 4° after 2 hours of the SLEEP CYCLE.

SLEEP FUNCTION DISPLAY

10. DRY - This function operates to control humidity within a conditioned space. It measures the difference between set point and the actual room temperature. An algorithm determines how far above set point the actual room temperature is to set point temperature and selects periods of water valve operation and low fan operation. The greater the difference between room temperature and set point temperature prompts greater run time with less temperature. With less temperature differences, periods of fan and valve operation are called for in varying increments as determined by the difference. In this mode (low speed) fan operation will start 30 seconds after valve has opened and stops 30 seconds after valve has closed.

199




11. AUTO - This function will automatically control the system switching between heating and cooling operation. If the preset auto mode is cooling, a switch to heating operation will begin only if the actual room temperature is 7° below selected control set point. If the present auto mode is heating, a switch to cooling operation will begin only when the room temperature is 3° above selected control set point. 12. TRANSMISSION INDICATOR - Blinks twice to indicate that transmission has taken place between remote and receiver. - Beeps indicate fan coil acknowledging receipt of transmission.

Before Installing, Programming or Operating, PLEASE READ ALL INSTRUCTIONS

Replacing Existing ThermostatMost thermostats have three parts: • The cover, which may snap or hinge over the existing thermostat. • The electronics or body, which controls the existing system.• The sub-base, where the wires attach through the wall to the existing system.

1. Always turn off power to the air conditioning and heating system prior to removing existing thermostat.2. Carefully remove the cover and electronics body from the old thermostat sub-base. Depending on the brand, these parts may pull off or need to be unscrewed. The old sub-base should remain wired and on the wall until steps 4 and 5.3. Label every old wire with the letter of the connection to which the wire is attached. Example letters are R, M, and Y etc. Depending on the brand of the old thermostat, your letters may be different.4. After labeling the old wires, loosen each connection and remove them from old sub-base. Secure the wires to prevent them from slipping into the hole in the wall.5. Remove the old sub-base from the wall, again being careful that the wires do not slip into the hole in the wall.6. Use the chart below to determine the new thermostat connections. As an example, if the old thermostat had a G or F connection, it goes to G on the new thermostat. Using a pencil and the chart below, circle the letter of each wire removed from the old thermostat.

Installation2 cont.

Installing New Thermostat

NOTE: When installing this thermostat in a new location, following a few simple guidelines and the applicable building codes will give the best results. Install the thermostat in a location that provides good airflow by avoiding areas behind doors, near corners, air vents, direct sunlight or heat generating devices. The wiring must conform to all building codes and ordinances as required by local and national code authorities having jurisdiction for this installation.

1. Always turn off the power to the air conditioning and heating system prior to installing this thermostat.2. Locate the release latch on the bottom (not the back) of the thermostat. Press the release latch in and separate the body from the sub-base of the thermostat. 3. Set the thermostat electronics and cover down on a clean surface. Place the sub-base on the wall in the desired location.4. Using the slotted mounting holes in the sub-base, mark the placement of the mounting holes through the slots and onto the wall. Ensure the wires come out of the wall into the center hole of the sub-base.5. After verifying the drill will not damage items in the wall, use a 3/16 drill to create the mounting holes. Gently tap the supplied plastic anchors into the holes in the wall.6. Place the thermostat sub-base against the wall in the desired location. Ensure the thermostat is level, the wires are inserted in the opening, and the mounting holes are aligned with the slots on the sub-base.7. Fasten sub-base to wall using the supplied screws into the plastic wall anchors.8. Connect wires to the quick wiring terminal blocks. Use the wiring diagram chart to ensure the old and new connections are correct.9. To prevent electrical shorts and potential damage to the thermostat, make sure all wire connections are secure and not touching each other.10. Ensure the cover is still installed on the body, and install them onto the sub-base. To do so, use the mounting tabs on the top of the sub-base as a guide hinge, and close up the thermostat case by pivoting the body and cover closed. The latch on the bottom of the thermostat will click when the case is properly closed. 11. Flip the front thermostat cover open and open the battery compartment door.12. Locate the positive [+] ends of the batteries and match them with the positive [+] terminals located in the battery compartment. Install the two new “AA” alkaline batteries (supplied). Close battery compartment door.13. Restore system power and proceed to Programming Installer Settings.

Description of Options

1. Selects the programming mode, either full 7 day or 5-2 day (weekday-weekend) programming or non-programmable.2. Enables or disables the ARM™ feature. During ARM™, room temperature is recovered gradually by turning on the heating or cooling before the end of the set back period. In a multi-stage configuration, room temperature is recovered gradually by using only the first stage heating or cooling until the last 20 minutes, to minimize the use of the 2nd stage heating or cooling. The set point temperature is changed to that of the upcoming comfort program temperature. ARM™ does not operate when the unit is in the temporary or permanent HOLD mode if the program is temporarily overridden or if emergency heat is selected for multi-stage heat pumps. If the ARM™ feature is disabled the thermostat will recover the set point temperature at the programmed set point time after the setback period ends. (continued on page 6)

3. Selects single stage conventional (11C), 2 stage conventional (22C), single stage heat pump (11HP), or 2 stage heat pump (22HP). Any change made to the system type resets Installer Options 4, 5, 6, 9 and 10 to their default values dependent on system selected.4. Selects between 1st stage gas or electric heat. This Installer Option is not available with a heat pump system.5. Selects between 2nd stage gas or electric heat. This Installer Option is only available with a 2 stage heat pump system.6. For heat pump units with an electric auxiliary stage, both the first and second stages of heating will run when a call for second stage heat is made. For heat pump units with a fossil fuel auxiliary stage, the first stage will be locked out one minute after a second stage heat call, and the second stage will only be used.7. During the COOL mode of normal operation the fan will stay on for 60 seconds after the cooling system has satisfied the set point temperature and has turned off the compressor. This allows the system to provide higher efficiency during cooling operation.8. This thermostat includes an automatic compressor protection feature to avoid potential damage to the cooling system from short cycling. This thermostat automatically provides a delay after turning off the cooling system output to protect the compressor. This protection is also present in the heat mode of operation on single stage heat pump systems to protect the compressor.9. This thermostat provides cold weather compressor protection by locking out the compressor stage (1st stage) of heating for a period of time after a power outage greater than 60 minutes. The lockout period is one hour less than the outage time, up to a maximum of 12 hours. During that period of time, the auxiliary heat stage will still be available to maintain the set point temperature. The compressor lockout can be disabled by setting this option to OFF.10. Select between turning the AC power interrupt warning off or on. During a power loss, the thermostat will display an outage warning. The system clock will continue to run, and all settings will be maintained until the outage period is over. This Installer Option is only available when thermostat is installed as a hardwired unit.11. Selects preferred temperature scale of either ºF or ºC.

NOTE: Any changes to Installer Options 1 or 11 will cause all User Options and Programming to reset to their default values if the User Options were previously programmed. See Section 5.

• Do not short (or jumper) across terminals on the gas valve or at the heating or cooling system control board to test the thermostat installation. This could damage the thermostat and void the warranty. • Do not select COOL mode of operation if the outside temperature is below 50˚ F (10˚ C). This could possibly damage the controlled cooling system and may cause personal injury.• This thermostat includes an automatic compressor protection feature to avoid potential damage to the cooling system from short cycling. This thermostat automatically provides a 5-minute delay after turning off the cooling or heating system output to protect the compressor. (continued on page 7)

Setting Thermostat User Options

The default user options are compatible with most systems and applications. They are normally set at the time of installation and usually do not require any modification under normal operating conditions.

NOTE: If at any time while in the user options mode, you do not wish to make any further changes, you can wait 30 seconds without pressing any keys to return to the normal operating mode.NOTE: The first and second stage differential settings are the same for both the heating and cooling systems.

Setting the First and Second Stage Differentials

First Stage DifferentialThe default setting is 0.5˚ F (0.25˚ C). The room temperature must change 0.5˚ F (0.25˚ C) from the set point temperature before the thermostat will call for heating or cooling.

1. In normal operating mode, press and hold the RETURN button for 4 seconds. The LCD display will show "d1 x", where "x" equals the ˚F / ˚C differential setting. This is the current temperature differential setting.

2. Press the or button to set the temperature differential to your desired setting of 0.5˚, 1˚, or 2˚ F (0.3˚, 0.5˚, or 1.0˚ C).

Second Stage Differential – Only Available on 2 Stage Systems

The default setting is 2˚ F (1.0˚C). This means that the room temperature must change 2˚ F (1.0˚ C) in addition to the first stage differential setting before the thermostat will initiate the system in heating or cooling.

3. Press the RETURN button again and the LCD display will show "d2 x", where "x" equals the ˚F / ˚C differential setting. This is the current second stage differential setting.

Setting Your Energy Saving Programs–Tips Before Starting (continued)

NOTE: If the 7 day programming mode was selected during the Installer Setup (section 3), the default program will use the weekday times and temperatures shown above for all 7 days. The programming mode can be switched between weekday-weekend and 7 day at any time by programming the Installer Options (see section 3).

• Make sure you place the system switch in the HEAT or COOL modes of operation as appropriate. You should not enter a program in the OFF position.• When you place the system switch in the COOL or HEAT modes of operation, the appropriate indicator will also appear in the LCD display when the system is running.• When you place the system switch in the OFF mode the display will indicate OFF.

Programming Overview For 7 Day Programming Mode

The 7 Day mode has separate Whole Week or Individual Day programming to allow you to change the daily set point times and temperatures to meet your individual schedule needs. The Whole Week programming can be used to set the main portion of your schedule, allowing you to later modify specific days of the week as required using the Individual Day programming capabilities.

Whole Week - allows you to program all seven days (M, TU, W, TH, F, SA, SU will show in display) at the same time. Then you can use individual day programming to fine tune your program for the few set point times or temperatures that you may wish to change.Individual Days - allows you to program each day of the week individually to give you the greatest schedule flexibility. Often used to fine tune programming after initially programming.

IMPORTANT NOTE! When in Whole Week programming, the thermostat will check if all of the days of that group have the same program set point times and temperatures. If so, the set point time and temperature of the individual set point will be displayed. Otherwise, the individual set point time and temperature will be blanked. The user is allowed to change the daily programs for this set point time and temperature by pressing the or button. This will reset all the daily programs of the group for that specific individual set point time and temperature to the startup default for that set point. Continued pressing of the or button by the user will change set point time and temperature settings as desired.

Locking the Keypad

To prevent accidental or undesired adjustment of the thermostat, the Keypad Lock feature disables the operation of the keypad except for the backlight key. In order to lock the keypad, press and hold Both and buttons together at the same time for 5 seconds. The LOCK segment in the display will flash once per second. When LOCK appears continuously, release both and buttons. The keypad is now locked.

To unlock the keypad, press and hold the and buttons together at the same time for 1 second. The LOCK segment will disappear and the keypad will become unlocked.

Adaptive Recovery Mode (ARM™)

In order to maximize comfort and energy efficiency, this thermostat is equipped with an Adaptive Recovery Mode (ARM™). This feature minimizes the amount of time required by heating or cooling system to reach the new set point after a setback period is completed, and assures your desired temperature is achieved at your set program times.

This feature activates when recovering room temperature from setback programs to comfort programs, so it will only take place when the current (heating) program set point temperature is lower than the upcoming program set point temperature, or the current (cooling) program set point temperature is higher than the upcoming program set point temperature.

During ARM™, room temperature is recovered gradually by turning on the heating or cooling before the end of the setback period.

ARM™ does not operate when the unit is in the HOLD mode, if the program is temporarily overridden, or if it has been disabled in the Installer Settings.

Recirculating Fan Feature (see section 5)

The Recirculating Fan Mode provides more even temperature distribution and improves indoor air quality by circulating air through the furnace filtration system more often. The Recirculating Fan Mode can be selected by moving the fan switch to the recirculate position( ). If no call for heating or cooling occurs within the fan off cycle set in section 4, the fan will run for 12 minutes. The highest setting, 120 minutes (factory default), will run the fan least often–9% minimum run time. The lowest setting, 40 minutes, will run the fan most often–23% minimum run time. During any call for heating or cooling, the fan operates in the AUTO mode. The Recirculating Fan feature is available in allsystem modes.

Auxiliary Heat Fossil Fuel Option

This thermostat is equipped with an auxiliary heat option which is set at installation for either an electric or fossil fuel (gas, oil or propane) auxiliary heat source. For heat pump units with an electric auxiliary stage, both the first and second stages of heating will run when a call for second stage heat is made.For heat pump units with a fossil fuel auxiliary stage, the first stage will be locked out one minute after a second stage heat call, and the second stage alone will be used.

Compressor Protection and AC Power Monitor

This thermostat includes an automatic compressor protection feature to avoid potential damage to the cooling system from short cycling. This thermostat automatically provides a 5-minute delay after turning off the cooling system output to protect the compressor. This protection is also present in the heat mode of operation on heat pump systems to protect the compressor.

NOTE: The installer can reset the thermostat and bypass the compressor protection features by pressing the RESET button. This will erase all entered programs, current time of day, day of week and other user settings and should only be used during installation for testing purposes or to reset a thermostat to regain normal operation. This will return all thermostat settings to their default values. The user will have to reprogram all of the erased settings.

This thermostat also provides cold weather compressor protection by locking out the compressor stage (1st Stage) of heating for a period of time after a power outage greater than 60 minutes. The lockout period is one hour less than the outage time, up to a maximum of 12 hours. During that period of time, the auxiliary heat stage will still be available to maintain the set point temperature. The compressor lockout can be manually overridden at any time by moving the system switch to the OFF position momentarily, then back to the heat position.

During a power loss, the thermostat will display an outage warning. The system clock will continue to run, and all settings will be maintained until the outage period is over.

Low Battery Detection and Replacement

This thermostat requires two (2) properly installed “AA” Alkaline batteries to maintain the system clock and to provide power for the thermostat if 24 volt AC power is not connected to the terminal block.

This thermostat is equipped with a low battery detection feature that constantly monitors the batteries during normal operating mode to determine whether they have sufficient power to provide proper operation.

When this feature determines that the battery status is low, a solid low battery indicator will appear in the display. It is recommended that the batteries be replaced immediately to maintain system operation and / or clock settings. If the battery continues to be low, the icon will flash every 2 seconds for 30 days. After 30 days the battery indicator will start to flash every 1 second. Replace batteries immediately.

Replacing the Batteries

1. Open the front cover and locate the battery compartment door.2. Gently remove the two "AA" alkaline batteries located in the battery compartment. 3. Install two new "AA" alkaline batteries into battery compartment. Make sure to match the positive (+) ends of the batteries with the positive (+) terminals located in the battery compartment.4. Close battery compartment and verify that the low battery indicator does not appear in the display.

ViegaPEX™ Barrier Hydronic Radiant HeatTubingScopeThis specification designates the requirements for ViegaPEX Barrier cross-linked polyethylene (PEX) tubing for use in hydronicradiant heating systems.ViegaPEX Barrier includes an oxygen barrier layer that helps restrict the passage of oxygen throughthe wall of the tubing.All ViegaPEX is manufactured and tested to the requirements of ASTM F876 and F877 and is CTS-OD(copper tube size outer dimension controlled) with an SDR - (standard dimension ratio) 9 wall thickness.ViegaPEX Barrier iscompatible with both Viega PEX Press fittings and F1807 PEX Crimp fittings.Viega has no control over the quality of othermanufacturers, therefore, we do not extend any warranty to those components that are not supplied byViega.

MaterialsViegaPEX Barrier tubing is produced from cross-linkable, high density polyethylene resin.This cross-linkable resin is producedby grafting organo-silane molecules onto a base polyethylene chain.A catalyst that initiates the cross-linking process is blendedwith the resin before extrusion.Cross-linking is conducted after extrusion by exposing the tubing to heat and moisture (steam).ViegaPEX Barrier includes 4 layers.The first layer is the cross-linked, high density polyethylene.The second layer is an adhesivefor the third layer, the ethylene vinyl alcohol layer (EVOH oxygen barrier).The fourth layer is another very thin layer ofpolyethylene, put on the outside to protect the EVOH layer from damage.EVOH is highly resistant to the passage of oxygen.

Marking and CertificationTubing is marked with manufacturer, ViegaPEX Barrier, nominal size, rating, codes and standards, approvals, date, materialcode and location of production (i.e., 0000FT Viega ViegaPEX Barrier™ 5/16" SDR-9 100 PSI @ 180°F [ NSF-pw U.P.CodeASTM F876/F877] ICBO ES ER-5287 PEX1006 Date Code Material Code Made in the USA 0002FT).Tubing is thirdparty tested to the requirements of the statedASTM standards.Tubing includes incremental footage markings to assist with looplayout.ViegaPEX Barrier is certified to NSF 61 and 14 for use as part of, or connected to a potable water system.

FostaPEX™ High Density Cross-linked Polyethylene (PEX)ScopeThis material specification designates the requirements for Viega FostaPEX multilayer pressure pipe for hot and cold waterdistribution tubing and hydronic radiant heating applications.All FostaPEX tubing has a fully dimensioned inner PEX core to thecopper tube size dimension (CTS), SDR-9 wall thickness and meets the respective requirements of ASTM Standard F876 andF877.

MaterialsThe multi-layered construction of the FostaPEX tubing is made from one full dimensional inner PEX core with an aluminum andouter PE layer surrounding it.This construction allows the inner layer alone to meet all temperature and pressure requirements ofthe system.Using the prep tool to remove the outer layers allows the use of the standard PureFlow PEX Press fitting system.

Marking and CertificationAll FostaPEX tubing is marked with the nameViega as the manufacturer, nominal size, plastic tubing material designation code,design pressure and temperature ratings, relevant ASTM standards, manufacturing date and production code, as well as theNSF-pw stamp, indicating third-party certification by NSF International for meeting and exceeding performance and toxicologicalstandards.NSF conducts random on-site inspections of Viega manufacturing facilities and independently tests FostaPEX tubingfor compliance with physical and toxicological standards. FostaPEX is also certified to meet the Uniform Plumbing Code, and theICBO Evaluation Service.

Recommended UsesFostaPEX tubing is intended and recommended for use in hot and cold potable water distribution systems and hydronic radiantheating and cooling systems. LikeViegaPEX Barrier, which has a barrier layer that resists the passage of oxygen through thewall of the tubing, the aluminum layer in FostaPEX offers even higher resistance to oxygen permeation in radiant heatingapplications. FostaPEX tubing can also be used in water service applications and is virtually impermeable to any soilcontaminents.Design temperature and pressure ratings for FostaPEX are 160 psi @ 73°F, 100 psi @ 180°F, and 80 psi @200°F. For information on the suitability for other hot and cold water applications not listed here, consult with your Viegarepresentative.

Handling and InstallationFostaPEX cross-linked polyethylene tubing is tough yet flexible.The aluminum layer allows tubing to be bent into position andremain in position when released.However, use of these materials in hot and cold water distribution systems must be inaccordance with good plumbing practices, applicable code requirements, and current installation practices available fromViega.FostaPEX is manufactured to meet written national standards.Contact a Viega representative or the applicable codeenforcement bureau for information about approvals for specific applications.

Viega warrants that PEX Press hand and Pneumatic PEX Hammer tools sold by Viega, under normal conditions of use, shall be free from failure caused by manufacturing defects for a period of two (2) years from date of sale.

Under this limited warranty, you only have a right to reimbursement if the failure or leak resulted from a manufacturing defect in the products covered by this warranty and the failure or leak occurred during the warranty period. You do not have a remedy or right of reimbursement under this warranty and the warranty does not apply if the failure or any resulting damage is caused by (1) components in the systems other than those manufactured or sold by Viega or components not recommended for use in the systems with the particular tubing used; (2) not installing, inspecting, or testing the tubing in accordance with Viega’s installation instructions at the time of the installation, applicable code requirements and accepted industry practices (for example, guidelines of the Radiant Panel Association); (3) improper design, including determining proper heat-load, of the system or improper maintenance of the system; (4) exposure to unauthorized solvents or chemicals, antifreeze, rust inhibitor or other treatment fluids; freezing; or by failure to appropriately limit recommended water temperature levels or other misuse or abuse of the tubing in the handling of the tubing prior to or during installation or by other construction activity on the property; (5) acts of nature such as earthquakes, fire, flood, wind, or lightning.

In the event of a leak or other failure in the system, it is the responsibility of the property owner to obtain and pay for the repairs. Only if the warranty applies will Viega be responsible for reimbursement under this warranty. The part or parts which you claim failed should be kept and Viega contacted by writing to the address below or telephoning 1-877-843-4262 within thirty (30) days after the leak or other failure and identifying yourself as having a warranty claim. You should be prepared to ship, at your expense, the product which you claim failed due to a manufacturing defect, document the date of installation, and the amount of any claimed bills for which you claim reimbursement. Within a reasonable time after notification, Viega will investigate the reasons for the failure, which includes the right to inspect the product at Viega and reasonable access to the site of the damage in order to determine whether the warranty applies. Viega will notify you in writing of the results of its review.
