When any compressor bearing unit is connected to a weak power supply, starting current will generate a signifi cant “sag” in the voltage which reduces the starting torque of the compressor motor and increases the start time. This will infl uence the rest of the electrical system in the building by lowering the voltage to the lights. This momentary low voltage causes “light dimming”. The total electrical system should be evaluated with an electrician and HVAC technician. The evaluation should include all connections, sizes of wires, and size of the distribution panel between the unit and the utility’s connection. The transformer connection and sizing should be evaluated by the electric utility provider.

Heating Cooling

LWT = EST - HE GPM x 500*

LWT = EST + HR GPM x 500*

HE = 500* x GPM x (EWT - LWT) HR = 500* x GPM x (LWT - EWT)

*500 = Constant factor for pure water. Brine should be 485.

Heating & Cooling Calculations

COP = Coeffi cient of Performance = BTU Output / BTU Input HR = Total Heat Of Rejection, Btu/hr

DH = Desuperheater Capacity, Btu/hr KW = Total Power Unit Input, Kilowatts

EER = Energy Effi ciency Ratio = BTU output/Watts input LWT = Leaving Source Water Temperature, Fahrenheit

EST = Entering Source Water Temperature, Fahrenheit LLT = Leaving Load Water Temperature, Fahrenheit

ELT = Entering Load Water Temperature, Fahrenheit TC = Total Cooling Capacity, Btu/hr

GPM = Water Flow, Gallons Per Minute HC = Heating Capacity, Btu/hr

HE = Total Heat Of Extraction, Btu/hr WPD = Water Pressure Drop, PSI & Feet of Water

Glossary

Notes:1. Desuperheater Capacity is based upon 0.4 GPM Flow per nominal ton at 90°F entering hot water temperature.2. Extrapolation data down to 25°F for heating and interpolation between EST & GPM data is permissible.3. EWT (Entering Water Temperature) is also called EST (Entering Source Temperature).4. Load fl ow rate is the same as the nominal source fl ow rate, approximately 3 GPM per ton.

Application Notes for Performance Data

Source Water Flow Selection

Proper fl ow rate is crucial for reliable operation of geothermal heat pumps. The performance data shows three fl ow rates for each entering water temperature (EST column). The general “rule of thumb” when selecting fl ow rates is the following:

Top fl ow rate: Open loop systems (1.5 to 2.0 gpm per ton)Middle fl ow rate: Minimum closed loop system fl ow rate(2.25 to 2.50 gpm/ton)Bottom fl ow rate: Nominal (optimum) closed loop system fl ow rate(3.0 gpm/ton)

Although the “rule of thumb” is adequate in most areas of North America, it is important to consider the application type before applying this “rule of thumb.” Antifreeze is generally required for all closed loop (geothermal) applications. Extreme Southern U.S. locations are the only exception. Open loop (well water) systems cannot use antifreeze, and must have enough fl ow rate in order to avoid freezing conditions at the Leaving Source Water Temperature (LWT) connection.

Calculations must be made for all systems without antifreeze to deter-mine if the top fl ow rate is adequate to prevent LWT at or near freezing conditions. The following steps should taken in making this calculation:

Determine minimum EST based upon your geographical area.Go to the performance data table for the heat pump model selected and look up the the Heat of Extraction (HE) at the “rule of thumb” water fl ow rate (GPM) and at the design Entering Load Temperature (ELT).

Calculate the temperature difference (TD) based upon the HE and GPM of the model.TD = HE / (GPM x 500).Calculate the LWT.LWT = EST - TD.

If the LWT is below 35-38°F, there is potential for freezing conditions if the fl ow rate or water temperature is less than ideal conditions, and the fl ow rate must be increased.

Example 1:EST = 50°F, ELT = 95°F.Model 036 Full Load, heating. Flow rate = 5 GPM. HE = 33,600 Btuh.TD = 33,600 / (5 x 500) = 13.4°FLWT = 50 - 13.4 = 36.6°FWater fl ow rate should be adequate under these conditions.

Example 2:EST = 40°F, ELT = 95°F.Model 036 Full Load, heating. Flow rate = 5 GPM. HE = 28,700 Btuh.TD = 28,700 / (5 x 500) = 11.5°FLWT = 40 - 11.5 = 28.5°FWater fl ow rate must be increased.

Section 5: Specifi cation Glossary & Calculations


Because the water-to-water machines have become so popular for providing heated water for a multitude of uses, we’ve provided the above chart for reference.

The obvious correlation is that the warmer the Source Entering Water Temperature, the hotter the Load Leaving Water Temperature can be, to a point. R410A can only handle up to about 125°F Load Leaving Water Temperature before putting the compressor at risk.

Actual usage, and choices of heat distribution devices need to follow the acceptableoperating conditions presented in the chart. If a question arises, please consult the Technical Services Department.

Section 6a: Operation Considerations


BUFFER TANKSVirtually all water-to-water heat pumps used for hydronic applications require a buffer tank to prevent equipment short cycling, and to allow lower fl ow rates through the water-to-water unit than through the hydronic delivery system. The following are considerations for buffer tank sizing.

• The size of the buffer tank should be determined based upon the predominant use of the water-to-water equipment (heating or cooling).

• The size of the buffer tank is based upon the lowest operating stage of the equipment. For example, a water-to-water heat pump with a two-stage compressor or two compressors may be sized for fi rst stage capacity, reducing the size of the tank (two-stage aquastat required).

• Pressurized buffer tanks are sized differently than non-pressurized tanks (see guidelines listed below).

Pressurized buffer tanks for predominately heating applications should be sized at one (1) U.S. gallon per 1,000 Btuh of heating capacity (10 gallons per ton may also be used) at the maximum entering source water temperature (EST) and the minimum entering load water temperature (ELT), the point at which the water-to-water unit has the highest heating capacity, usually 50-70°F EST and 80-90°F ELT.

For predominately cooling applications, pressurized buffer tanks should be sized at one (1) U.S. gallon per 1,000 Btuh of cooling capacity (10 U.S. gallons per ton may also be used) at the minimum EST and the maximum ELT, the point at which the water-to-water unit has the highest cooling capacity, usually 50-70°F EST and 50-60°F ELT.

Select the size of the tank based upon the larger of the calculations (heating or cooling).

Non-pressurized buffer tanks must also be sized based upon predominate use (heating or cooling) and based upon the lowest capacity stage. Requirements for storage are less according to the manufacturer of the HSS series non-pressurized buffer tank. Using the same conditions for maximum heating and cooling capacity mentioned above, non-pressurized buffer tanks require 6 U.S. gallons per ton.

“WARNING” Indicates potentially hazardous situation which, if not avoided, COULD result in death or serious injury.

“DANGER” Indicates an immediate hazardous situation which, if not avoided, WILL result in death or serious injury.

InspectionUpon receipt of any geothermal equipment, carefully check the shipment against the packing slip and the freight company bill of lading. Verify that all units and packages have been received. Inspect the packaging of each package and each unit for damages. Insure that the carrier makes proper notation of all damages or shortage on all bill of lading papers. Concealed damage should be reported to the freight company within 15 days. If not fi led within 15 days the freight company can deny all claims.

Note: Notify Roth’s shipping department of all damages within 15 days. It is the responsibility of the purchaser to fi le all necessary claims with the freight company.

Unit ProtectionProtect units from damage and contamination due to plastering (spraying), painting and all other foreign materials that may be used at the job site. Keep all units covered on the job site with either the original packaging or

equivalent protective covering. Cap or recap unit connections and all piping until unit is installed. Precautions must be taken to avoid physical damage and contamination which may prevent proper start-up and may result in costly equipment repair.

CAUTION DO NOT OPERATE THE GEOTHERMAL HEAT PUMP UNIT DURING BUILDING

CONSTRUCTION PHASE.

StorageAll geothermal units should be stored inside in the original packaging in a clean, dry location. Units should be stored in an upright position at all times. Units should not be stacked unless specially noted on the packaging.

Pre-InstallationSpecial care should be taken in locating the geothermal unit. Installation location chosen should include adequate service clearance around the unit. All units should be placed on a formed plastic air pad, or a high density, closed cell polystyrene pad slightly larger than the base of the unit. If units are being placed on racking, the unit must be placed on a solid foundation. All units should be located in an indoor area where the ambient temperature will remain above 55°F and should be located in a way that piping and ductwork or other permanently installed fi xtures do not have to be removed for servicing and fi lter replacement.

Pre-Installation Steps:

1. Compare the electrical data on the unit nameplate with packing slip and ordering information to verify that the correct unit has been shipped.

2. Inspect all electrical connectionsand wires. Connections must be clean and tight at the terminals, and wires should not touch any sharp edges or copper pipe.

3. Verify that all refrigerant tubing is free of dents and kinks. Refrigerant tubing should not be touching other unit components.


4. Before unit start-up, read all manuals and become familiar with unit components and operation. Thoroughly check the unit before operating.

5. For A-Coil installations, it is recommended that coil be sprayed with liquid detergent thoroughly and rinsed thoroughly before installation to assure proper drainage of condensate from the coil fi ns to eliminate water blowoff and to assure maximum coil performance. If not sprayed approximately 50 hours of break in time is required to achieve the same results.

CAUTION ALL GEOTHERMAL EQUIPMENT IS

DESIGNED FOR INDOOR INSTALLATION ONLY. DO NOT INSTALL OR STORE UNIT IN A CORROSIVE ENVIRONMENT OR IN A LOCATION WHERE TEMPERATURE AND HUMIDITY ARE SUBJECT TO EXTREMES.

EQUIPMENT IS NOT CERTIFIED FOR OUTDOOR APPLICATIONS. SUCH

INSTALLATION WILL VOIDALL WARRANTIES.

WARNING FAILURE TO FOLLOW THIS CAUTION MAY RESULT IN PERSONAL INJURY. USE CARE AND WEAR APPROPRIATE PROTECTIVE

CLOTHING, SAFETY GLASSES AND PROTECTIVE GLOVES WHEN SERVICING

UNIT AND HANDLING PARTS.

CAUTION BEFORE DRILLING OR DRIVING ANY

SCREWS INTO CABINET, CHECK TO BE SURE THE SCREW WILL NOT HIT ANY

INTERNAL PARTS OR REFRIGERANT LINES.

Section 8: Installation Introduction

Components

Master Contactor: Energizes Compressor and optional Hydronic Pump and/or Desuperheater pump package.

Logic Board: Logic Board operates the compressor and protects unit by locking out when safety switches are engaged. It also provides fault indicator(s).

Terminal Strip: Provides connection to the thermostat or other accessories to the low voltage circuit.

Transformer: Converts incoming (source) voltage to 24V AC.

Low Voltage Breaker: Attached directly to transformer, protects the transformer and low voltage circuit.

Reversing Valve: Controls the cycle of the refrigerant system (heating or cooling). Energized in cooling mode.

High Pressure Switch: Protects the refrigerant system from high refrigerant pressure, by locking unit out if pressure exceeds setting.

Low Pressure Switch: Protects the refrigerant system from low suction pressure, if suction pressure falls below setting.

Flow Switch (Freeze Protection Device): Protects the water heat exchanger from freezing, by shutting down compressor if water fl ow decreases.

Compressor (Copeland Scroll): Pumps refrigerant through the heat exchangers and pressurizes the refrigerant, which increases the temperature of the refrigerant.


Consumer Instructions: Dealer should instruct the consumer in proper operation, maintenance, fi lter replacements, thermostat and indicator lights. Also provide the consumer with the manufacturer’s Owner's Manual for the equipment being installed.

Roth D-I-Y Policy: Roth’s geothermal heat pumps and system installations may include electrical, refrigerant and/or water connections. Federal, state and local codes and regulations apply to various aspects of the installation. Improperly installed equipment can lead to equipment failure and health/safety concerns. For these reasons, only qualifi ed technicians should install a Roth built geothermal system.

Because of the importance of proper installation, Roth does not sell equipment direct to homeowners. Internet websites and HVAC outlets may allow for purchases directly by homeowners and do-it-yourselfers, but Roth offers no warranty on equipment that is purchased via the internet or installed by persons without proper training.

Roth has set forth this policy to ensure installations of Roth geothermal systems are done safely and properly. The use of well-trained, qualifi ed technicians helps ensure that your system provides many years of comfort and savings.

Equipment Installation: Special care should be taken in locating the unit. All units should be placed on a formed plastic air pad, or a high density, closed cell polystyrene pad slightly larger than the base of the unit. All units should be located in an indoor area were the ambient temperature will remain above 55°F and should be located in a way that piping and ductwork or other permanently installed fi xtures do not have to be removed for servicing and fi lter replacement.

Electrical: All wiring, line and low voltage, should comply with the manufacturer's recommendations, The National Electrical Code, and all local codes and ordinances.

Thermostat: Thermostats should be installed approximately 54 inches off the fl oor on an inside wall in the return air pattern and where they are not in direct sunlight at anytime.

Loop Pumping Modules: Must be wired to the heat pump’s electric control box. A special entrance knockout is provided below the thermostat entrance knockout. A pump module connection block, connected to the master contactor, and circuit breaker is provided to connect the Pump Module wiring.

Desuperheater Package: Water heating is standard on all residential units (units may be ordered without). It uses excess heat during both heating and cooling cycles, to provide hot water for domestic needs. A desuperheater exchanger (coil) located between the compressor and the reversing valve, extracts superheated vapor to heat domestic water; still satisfying its heating and cooling needs. The water circulation pump comes pre-mounted in all residential units, but must be electrically connected to the master contactor. Leaving it disconnected ensures that the pump will not run without a water supply.

The Desuperheater package can make up to 60% (depending on heat pump usage) of most domestic water needs, but a water heater is still recommended.

Desuperheater Piping: All copper tubes & fi ttings should be 5/8” O.D (1/2” nom) minimum with a maximum of 50ft separation. Piping should be insulated with 3/8” wall closed cell insulation.

Note: Copper is the only approved material for piping the desuperheater.

Section 9: Installation Considerations


Section 10: Unit Placement

UNIT PLACEMENTWhen installing a geothermal heating and cooling unit, there are several items the installer should consider before placing the equipment.

1. Service Access. Is there enough space for service access? A general rule of thumb is at least 2 feet in the front and 2 feet on at least one side.

2. Unit Air Pad. All geothermal heating and cooling equipment should be placed on either a formed plastic air pad, or a high density, closed cell polystyrene pad. This helps eliminate vibration noise that could be transmitted through the fl oor.

3. If units are being placed on racking, the unit must be placed on a solid foundation covering the full base of the unit. Also, utilize a foam pad between the unit and the rack.

4. The installer must verify that all applicable wiring, piping, and accessories are correct and on the job site.

PRE-INSTALLATIONBefore you fully install the geothermal equipment, it is recommended you go through this quick checklist before placing the equipment.

Fully inspect the unit after unpacking.

Locate the Unit Start-Up form from this manual and have it available as the unit installation proceeds.


Open Loop PipingPlacement of the components for an open loop system are important when considering water quality and long term maintenance. The water solenoid valve should always be placed on the outlet of the heat pump, which will keep the heat exchanger under pressure when the unit is not operating. If the heat exchanger is under pressure, minerals will stay in suspension. Water solenoid valves are also designed to close against the pressure, not with the pressure. Otherwise, they tend to be noisy when closing.

A fl ow regulator should be placed after the water solenoid valve. Always check the product specifi cation catalog for proper fl ow rate. A calculation must be made to determine the fl ow rate, so that the leaving water temperature does not have the possibility of freezing.

Other necessary components include a strainer, boiler drains for heat exchanger fl ushing, P/T ports and ball valves. Ball valves allow the water to be shut off for service, and also help when velocity noise is noticeable through the fl ow regulator. Spreading some of the pressure drop across the ball valves will lessen the

velocity noise. Always double check fl ow rate at the P/T ports to make sure the ball valve adjustments have not lowered water fl ow too much, and essentially taken the fl ow regulator out of the equation. It’s a good idea to remove the ball valve handles once the system is completed to avoid nuisance service calls.

Hose kits are optional, but make for an easier installation, since the P/T ports and connections are included. The hose also helps to isolate the heat pump from the piping system.

Since the heat pump can operate at lower waterfl ow on fi rst stage, two stage units typically include two water solenoid valves to save water. The fl ow regulators should be sized so that when one valve is open the unit operates at fi rst stage fl ow rate, and when both valves are open, the unit operates at full load fl ow rate. For example, a 4 ton unit needs approximately 4 GPM on fi rst stage, and approximately 7 GPM at full load. The fl ow regulator after the fi rst valve should be 4 GPM, and the fl ow regulator after the second valve should be 3 GPM. When both valves are open, the unit will operate at 7 GPM.

Water QualityThe quality of the water used in geothermal systems is very important. In closed loop systems the dilution water (water mixed with antifreeze) must be of high quality to ensure adequate corrosion protection. Water of poor quality contains ions that make the fl uid “hard” and corrosive. Calcium and magnesium hardness ions build up as scale on the walls of the system and reduce heat transfer. These ions may also react with the corrosion inhibitors in glycol based heat transfer fl uids, causing them to precipitate out of solution and rendering the inhibitors ineffective in protecting against corrosion. In addition, high concentrations of corrosive ions, such as chloride and sulfate, will eat through any protective layer that the corrosion inhibitors form on the walls of the system.

Ideally, de-ionized water should be used for dilution with antifreeze solutions since de-

ionizing removes both corrosive and hardness ions. Distilled water and zeolite softened water are also acceptable. Softened water, although free of hardness ions, may actually have increased concentrations of corrosive ions and, therefore, its quality must be monitored. It is recommended that dilution water contain less than 100 PPM calcium carbonate or less than 25 PPM calcium plus magnesium ions; and less than 25 PPM chloride or sulfate ions.

In an open loop system the water quality is of no less importance. Due to the inherent variation of the supply water, it should be tested prior to making the decision to use an open loop system. Scaling of the heat exchanger and corrosion of the internal parts are two of the potential problems. The Department of Natural Resources or your local municipality can direct you to the proper testing agency. Please see Table 1 for guidelines.

Copper and cupro-nickel heat exchangers are not recommended for pool applications for water outside the range of the table. Secondary heat exchangers are required for applications not meeting the requirements shown above.4. Saltwater applications (approx. 25,000 ppm) require secondary heat exchangers due to copper piping between the heat exchanger and the unit fi ttings.

Table 1: Water Quality




Interior PipingAll interior piping must be sized for proper fl ow rates and pressure loss. Insulation should be used on all inside piping when minimum loop temperatures are expected to be less than 50°F. Use the table below for insulation sizes with different pipe sizes. All pipe insulation should be a closed cell and have a minimum wall thickness of 3/8”. All piping insulation should be glued and sealed to prevent condensation and dripping. Interior piping may consist of the following materials: HDPE, copper, brass, or rubber hose (hose kit only). PVC is not allowed on pressurized systems.

Table 2: Pipe Insulation

Typical Pressurized Flow Center InstallationThe fl ow centers are insulated and contain all fl ushing and circulation connections for residential and light commercial earth loops that require a fl ow rate of no more than 20 gpm. 1-1/4” fusion x 1” double o-ring fi ttings (AGA6PES) are furnished with the double o-ring fl ow centers for HDPE loop constructions. Various fi ttings are available for the double o-ring fl ow centers for different connections. See fi gure 2 for connection options. A typical installation will require the use of a hose kit. Matching hose kits come with double o-ring adapters to transition to 1” hose connection.

Note: Threaded fl ow centers all have 1” FPT connections. Matching hose kits come with the AGBA55 adapter needed to transition from 1” FPT to 1” hose.

Typical Non-Pressurized Flow Center InstallationStanding column fl ow centers are designed to operate with no static pressure on the earth loop. The design is such that the column of water in the fl ow center is enough pressure to prime the pumps for proper system operation and pump reliability. The fl ow center does have a cap/seal, so it is still a closed system, where the fl uid will not evaporate. If the earth loop header is external, the loop system will still need to be

fl ushed with a purge cart. The non-pressurized fl ow center needs to be isolated from the fl ush cart during fl ushing because the fl ow center is not designed to handle pressure. Since this is a non-pressurized system, the interior piping can incorporate all the above-mentioned pipe material options (see interior piping), including PVC. The fl ow center can be mounted to the wall with the included bracket or mounted on the fl oor as long as it is properly supported.

Antifreeze OverviewIn areas where minimum entering loop temperatures drop below 40°F, or where piping will be routed through areas subject to freezing, antifreeze is required. Alcohols and glycols are commonly used as antifreeze. However, local and state/provincial codes supersede any instructions in this document. The system needs antifreeze to protect the coaxial heat exchanger from freezing and rupturing. Freeze protection should be maintained to 15°F below the lowest expected entering loop temperature. For example, if 30°F is the minimum expected entering loop temperature, the leaving loop temperature could be 22 to 25°F. Freeze protection should be set at 15°F (30-15 = 15°F). To determine antifreeze requirements, calculate how much volume the system holds. Then, calculate how much antifreeze will be needed by determining the percentage of antifreeze required for proper freeze protection. See Tables 3a and 3b for volumes and percentages. The freeze protection should be checked during installation using the proper hydrometer to measure the specifi c gravity and freeze protection level of the solution.

Antifreeze CharacteristicsSelection of the antifreeze solution for closed loop systems require the consideration of many important factors, which have long-term implications on the performance and life of the equipment. Each area of concern leads to a different “best choice” of antifreeze. There is no “perfect” antifreeze. Some of the factors to consider are as follows (Brine = antifreeze solution including water):

Safety: The toxicity and fl ammability of the brine (especially in a pure form).

Cost: Prices vary widely.

Thermal Performance: The heat transfer and viscosity effect of the brine.

Corrosiveness: The brine must be compatible with the system materials.

Stability: Will the brine require periodic change out or maintenance?

Convenience: Is the antifreeze available and easy to transport and install?

Codes: Will the brine meet local and state/provincial codes?

The following are some general observations about the types of brines presently being used:

Methanol: Wood grain alcohol that is considered toxic in pure form. It has good heat transfer, low viscosity, is non-corrosive, and is mid to low price. The biggest down side is that it is fl ammable in concentrations greater than 25%.

Ethanol: Grain alcohol, which by the ATF (Alcohol, Tobacco, Firearms) department of the U.S. government, is required to be denatured and rendered unfi t to drink. It has good heat transfer, mid to high price, is non-corrosive, non-toxic even in its pure form, and has medium viscosity. It also is fl ammable with concentrations greater than 25%. Note that the brand of ethanol is very important. Make sure it has been formulated for the geothermal industry. Some of the denaturants are not compatible with HDPE pipe (for example, solutions denatured with gasoline).

Propylene Glycol: Non-toxic, non-corrosive, mid to high price, poor heat transfer, high viscosity when cold, and can introduce micro air bubbles when adding to the system. It has also been known to form a “slime-type” coating inside the pipe. Food grade glycol is recommended because some of the other types have certain inhibitors that react poorly with geothermal systems. A 25% brine solution is a minimum required by glycol manufacturers, so that bacteria does not start to form.

Ethylene Glycol: Considered toxic and is not recommended for use in earth loop applications.

GS4 (POTASSIUM ACETATE): Considered highly corrosive (especially if air is present in the system) and has a very low surface tension, which causes leaks through most mechanical fi ttings. This brine is not recommended for use in earth loop applications.

Section 12: Antifreeze


Notes: 1. Consult with your representative or

distributor if you have any questions regarding antifreeze selection or use.

2. All antifreeze suppliers and manufacturers recommend the use of either de-ionized or distilled water with their products.

Antifreeze ChargingCalculate the total amount of pipe in the system and use Table 3a to calculate the amount of volume for each specifi c section of the system. Add the entire volume together, and multiply that volume by the proper antifreeze percentage needed (Table 3b) for the freeze protection required in your area. Then, double check calculations during installation with the proper hydrometer and specifi c gravity chart (Figure 6) to determine if the correct amount of antifreeze was added.

Plumbing Installation

NOTE: All plumbing and piping connections must comply with local plumbing codes.

TIP: Measure the distance above the fl oor or shelf that the water heater is setting on, to where the drain valve is located. This distance must be greater than one-half the width of the tee you’re about to install, or you won’t be able to thread the tee on to the water heater.

Note: Copper is the only approved material for piping the desuperheater.

1. Disconnect electricity to water heater.

2. Turn off water supply to water heater.

3. Drain water heater. Open pressurerelief valve.

4. Remove drain valve and fi tting fromwater heater.

5. Thread the ¾” MPT x 3-1/2” nipple into the water heater drain port. Use Tefl on tape, or pipe thread sealant on threads.

6. Thread the branch port of the ¾” brass tee to the other end of the nipple.

7. Thread one of the copper adaptors into the end of the tee closest to the heat pump.

8. Thread the drain valve into the other end of the nipple. See Figure 7.

9. Above the water heater, cut the incoming cold water line. Remove a section of that line to enable the placement of the copper tee.

10. Insert the copper tee in the cold water line. See Figure 8.

11. Thread the remaining two ½”SWT x ¾”MPT copper adaptors into the ¾” FPT fi ttings on the heat pump, marked HOT WATER IN and HOT WATER OUT.

12. Run interconnecting ½” copper pipe from the HOT WATER OUT on the heat pump, to the copper adaptor located on the tee at the bottom of the water heater (Step 7).

13. Run interconnecting ½” copper pipe from the HOT WATER IN on the heat pump, to the copper tee in the cold water line (Step 10).

14. Install an air vent fi tting at the highest point of the line from step 13 (assuming it’s the higher of the two lines from the heat pump to the water heater). See Figure 8.

Section 13: Desuperheater Installation

Desuperheater InstallationUnits that ship with the desuperheater function also ship with a connection kit.

Note: Desuperheater capacity is based on 0.4 GPM Flow per nominal ton at 90°F entering hot water temperature.

Note: Units that are shipped with a desuperheater do not have the desuperheater pump wires connected to the electrical circuit, to prevent accidentally running the pump while dry. Pump has to be connected to the electric circuit (master contactor) when the lines from the water heater are installed & airis removed.


15. Shut off the valve installed in the desuperheater line close to the tee in the cold water line. Open the air vent and all shut off valves installed in the “hot water out”.

16. Turn the water supply to the water heater on. Fill water heater. Open highest hot water faucet to purge air from tank and piping.

17. Flush the interconnecting lines, and check for leaks. Make sure air vent is shutoff when water begins to drip steadily from the vent.

MICROPROCESSOR FEATURES AND OPERATION Roth geothermal heat pump controls provide a unique modular approach for controlling heat pump operation. The control system uses one, two, or three printed circuit boards, depending upon the features of a particular unit. This approach simplifi es installation and troubleshooting, and eliminates features that are not applicable for some units.

A microprocessor-based printed circuit board controls the inputs to the unit as well as outputs for status mode, faults, and diagnostics. A status LED and an LED for each fault is provided for diagnostics.

Removable low voltage terminal strips provide all necessary terminals for fi eld connections. Not only are the thermostat inputs included, but there are also removable terminal strips for all of the accessory wiring for ease of installation and troubleshooting. Startup/Random StartThe unit will not operate until all the inputs and safety controls are checked for normal conditions. At fi rst power-up, the compressor is energized after a fi ve minute delay. In addition, a zero to sixty second random start delay is added at fi rst power-up to avoid multiple units from being energized at the same time.

Short Cycle Protection A built-in fi ve minute anti-short cycletimer provides short cycle protection ofthe compressor.

Component Sequencing DelaysComponents are sequenced and delayed for optimum space conditioning performance and to make any startup noise less noticeable.

Test Mode The microprocessor control allows the technician to shorten most timing delays for faster diagnostics by changing the position of a jumper located on the lockout board.

Water Solenoid Valve Connections Two accessory relay outputs at the terminal strip provide a fi eld connection for two types of water solenoid valves, a standard 24VAC

solenoid valve, or a 24VAC solenoid valve with an end switch. Additional fi eld wiring is no longer required for operation of the end switch.

Loop Pump Circuit Breakers(Single Compressor Units)The loop pump(s) and desuperheater pump are protected by control box mounted circuit breakers for easy wiring of pumps during installation. Circuit breakers eliminate the need to replace fuses.

Safety Controls The control receives separate signals for high pressure, low pressure, and low water fl ow. Upon a continuous 30-second measurement of the fault (immediate for high pressure), compressor operation is suspended (see Fault Retry below), and the appropriate LED fl ashes. Once the unit is locked out (see Fault Retry below), an output (terminal “L”) is made available to a fault LED at the thermostat (water-to-water unit has fault LED on the corner post).

Low Pressure: If the low pressure switch is open for 30 continuous seconds, the compressor operation will be interrupted, and the control will go into fault retry mode. At startup, the low pressure switch is not monitored for 90 seconds to avoid nuisance faults.

High Pressure: If the high pressure switch opens, the compressor operation will be interrupted, and the control will go into fault retry mode. There is no delay from the time the switch opens and the board goes into fault retry mode. There is also no delay of switch monitoring at startup.

Flow Switch: If the fl ow switch is open for 30 continuous seconds, the compressor operation will be interrupted, and the control will go into fault retry mode. At startup, the fl ow switch is not monitored for 30 seconds to avoid nuisance faults.

FAULT RETRY All faults are retried twice before fi nally locking the unit out. The fault retry feature is designed to prevent nuisance service calls. There is an anti-short cycle period between fault retries. On the third fault, the board will go into lockout mode.

Section 14: Controls


Over/Under Voltage Shutdown The lockout board protects the compressor from operating when an over/under voltage condition exists. The control monitors secondary voltage (24VAC) to determine if an over/under voltage condition is occurring on the primary side of the transformer. For example, if the secondary voltage is 19 VAC, the primary voltage for a 240V unit would be approximately 190V, which is below the minimum voltage (197V) recommended by the compressor manufacturer. This feature is self-resetting. If the voltage comes back within range, normal operation is restored. Therefore, over/under voltage is not a lockout.

Under voltage (18 VAC) causes the compressor to disengage and restart when the voltage returns to 20 VAC. Over voltage (31 VAC) causes the compressor to disengage and restart when the voltage returns to 29 VAC.

During an over or under voltage condition, all fi ve fault LEDs will blink (HP + LP + FS + CO + Status). When voltage returns to normal operation, the four fault LED’s will stop blinking, but the status LED will continue to fl ash. While the board LEDs are fl ashing, the thermostat fault light will be illuminated.

Intelligent Reset If the thermostat is powered off and back on (soft reset), the board will reset, but the last fault will be stored in memory for ease of troubleshooting. If power is interrupted to the board, the fault memory will be cleared.

Diagnostics The lockout board includes fi ve LEDs (status, high pressure, low pressure, low water fl ow, condensate overfl ow) for fast and simple control board diagnosis. Below is a table showing LED function.

LED Color Location1 Function Normal Operation Fault Retry2 Lockout2

Green Top High Pressure OFF Flashing3 ON3

Notes:1. Looking at the board when the LEDs are on the right hand side2. If all fi ve lights are fl ashing, the fault is over/under voltage3. Only the light associated with the particular fault/lockout will be on or fl ashing.

For example, if a high pressure lockout has occurred, the top green light will be on. The orange, red, and yellow lights will be off

4. Status lights will be off when in test mode5. Flashes alternately with the fault LED

Table 4a: LED Identifi cation



Hot Water Pump Control Controls for high water temperature and low compressor discharge line temperature prevent the hot water (desuperheater) pump from operating when the leaving water temperature is above 130°F, or when the compressor discharge line is too cool to provide adequate water heating.

Lockout Board Jumper SelectionThe lockout board includes three jumpers for fi eld selection of various board features.

Water Solenoid Valve Delay (WSD): When the WSD jumper is installed, the “A” terminal is energized when the compressor is energized. When the jumper is removed, the “A” terminal is energized 10 seconds after the compressor. If using the Taco water solenoid valve (or a valve with an end switch), the unit terminal strip includes a means for connecting a valve of this type. The WSD jumper should be installed. If using a fast opening valve without an end switch, the jumper should be removed.

Test Mode (TEST): When the TEST jumper is installed, the board operates in the normal mode. When the jumper is removed, the board operates in test mode, which speeds up all delays for easier troubleshooting. When service is complete, the jumper must be re-installed in order to make sure that the unit operates with normal sequencing delays. While test jumper is removed, the status (bottom green light) will remain off.

Over/Under Voltage Disable (O/V): When the O/V jumper is installed, the over/under voltage feature is active. When the jumper is removed, the over/under voltage feature is disabled. On rare occasions, variations in voltage will be outside the range of the over/under voltage feature, which may require removal of the jumper. However, removal of the jumper could cause the unit to run under adverse conditions, and therefore should not be removed without contacting technical services. An over/under voltage condition could cause premature component failure or damage to the unit controls. Any condition that would cause this fault must be thoroughly investigated before taking any action regarding the jumper removal. Likely causes of an over/under voltage condition

include power company transformer selection, insuffi cient entrance wire sizing, defective breaker panel, incorrect transformer tap (unit control box), or other power-related issues.

HYDRONIC AIR HANDLER:ECM fan/hydronic chilled water/hot water coil

Thermostat Wiring / Fan Speed Notes For two-stage thermostats, use both Y1 and Y2. For single stage thermostats, jumper Y1 and Y2, and use the “CFM Y2” column in table 6b for determining jumper location. The ECM control board in the air handler is the thermostat connection point. Wire nut the thermostat wiring to the leads connected to the 1/4” spades on the ECM board.

For dehumidifi cation in cooling, cut the resistor at the “DEHUMIDIFY” LED. Use either the HUM terminal (reverse logic -- designed to be used with a humidistat) to lower the fan speed when dehumidifi cation is needed, or if the HUM terminal is not connected (and the resistor is cut), the air handler will operate at a lower fan speed in cooling and normal fan speed in heating.

APSMA PUMP SHARING MODULEThe pump sharing module, part number APSMA, is designed to allow two units to share one fl ow center. With the APSMA module, either unit can energize the pump(s). Connect the units and fl ow center as shown in Figure 11, below. Figure 12 includes a schematic of the board. The module must be mounted in a NEMA enclosure or inside the unit control box. Local code supersedes any recommendations in this document.

PERFORMANCE CHECK:Heat of Extraction(HE)/Rejection(HR)Record information on the Unit Start-up Form

Equipment should be in operation for a minimum of 10 minutes in either mode – WITH THE HOT WATER GENERATOR TURNED OFF.

1. Determine fl ow rate in gallons per minute a. Check entering water temperature b. Check entering water pressure c. Check leaving water pressure

Once this information is recorded, fi nd corresponding entering water temperature column in Specifi cation Manual for unit.Find pressure differential in PSI column in Spec Manual. Then read the GPM column in Spec Manual to determine fl ow in GPM.

2. Check leaving water temperature of unit.FORMULA: GPM x water temp diff, x 485 (antifreeze) or 500 (fresh water) = HE or HR in BTU/HR

A 10% variance from Spec Manual is allowed. Always use the same pressure gauge & temperature measuring device.Water fl ow must be in range of Specifi cation Manual. If system has too much water fl ow, performance problems should be expected

Section 16: Troubleshooting


A: UNIT WILL NOT START IN EITHER CYCLE

Thermostat

Set thermostat on heating and highest temperature setting. Unit should run. Set thermostat on cooling and lowest temperature setting. Unit should run. Set fan to On position. Fan should run. If unit does not run in any position, disconnect wires at heat pump terminal block and jump R, G, Y. Unit should run in heating. If unit runs, replace thermostat with correct thermostat only.

Loose or broken wires Tighten or replace wires.

Blown Fuse/Tripped Circuit Breakers

Check fuse size, replace fuse or reset circuit breaker.Check low voltage circuit breaker.

Low Voltage CircuitCheck 24 volt transformer. If burned out or less than 24 volt, replace. Before replacing, verify tap setting and correct if necessary.

Water Flow (runs for 30 sec)

If water fl ow is low (less than 3.5 GPM), unit will not start. Make sure Pump Module or solenoid valve is connected (see wiring diagram). Water has to fl ow through the heat exchanger in the right direction (see labels at water fi tting connections) before the compressor can start. If water fl ow is at normal fl ow, use an ohmmeter to check if you get continuity at the fl ow switch. If no switch is open and fl ow is a normal fl ow, remove switch and check for stuck particles or bad switch.

B: UNIT RUNNING NORMAL, BUT SPACE TEMPERATURE IS UNSTABLE

ThermostatThermostat is getting a draft of cold or warm air. Make sure that the wall or hole used to run thermostat wire from the ceiling or basement is sealed, so no draft can come to the thermostat.Faulty Thermostat (Replace).


C: NO WATER FLOW

Pump Module

Make sure Pump Module is connected to the control box relay (check all electrical connections). For non-pressurized systems, check water level in Pump Module. If full of water, check pump. Close valve on the pump fl anges and loosen pump. Take off pump and see if there is an obstruction in the pump. If pump is defective, replace. For pressurized systems, check loop pressure. Repressurize if necessary. May require re-fl ushing if there is air in the loop.

Solenoid valve Make sure solenoid valve is connected. Check solenoid. If defective, replace.

D: IN HEATING OR COOLING MODE, UNIT OUTPUT IS LOWWater Water fl ow & temperature insuffi cient.

Load Side FlowCheck speed setting, check nameplate or data manual for proper speed, and correct speed setting.Check for dirty air fi lter—Clean or replace.Restricted or leaky ductwork. Repair.

Refrigerant chargeRefrigerant charge low, causing ineffi cient operation. Make adjustments only after airfl ow and water fl ow are checked.

Reversing valve

Defective reversing valve can create bypass of refrigerant to suction side of compressor. Switch reversing valve to heating and cooling mode rapidly. If problem is not resolved, replace valve. Wrap the valve with a wet cloth and direct the heat away from the valve. Excessive heat can damage the valve. Always use dry nitrogen when brazing. Replace fi lter/drier any time the circuit is opened.

E: IN HEATING OR COOLING MODE, UNIT OUTPUT IS LOW

Heat pump will not cool but will heat. Heat pump will not heat but will cool.

Reversing valve does not shift. Check reversing valve wiring. If wired wrong, correct wiring. If reversing valve is stuck, replace valve. Wrap the valve with a wet cloth and direct the heat away from the valve. Excessive heat can damage the valve. Always use dry nitrogen when brazing. Replace fi lter/drier any time the circuit is opened.

Water heat exchangerCheck for high-pressure drop, or low temperature drop across the coil. It could be scaled. If scaled, clean with condenser coil cleaner.

System undersized Recalculate conditioning load.

F: WATER HEAT EXCHANGER FREEZES IN HEATING MODEWater fl ow Low water fl ow. Increase fl ow. See F. No water fl ow.

Flow Switch Check switch. If defective, replace.

G: EXCESSIVE HEAD PRESSURE IN COOLING MODEInadequate water fl ow Low water fl ow, increase fl ow.


H: EXCESSIVE HEAD PRESSURE IN HEATING MODELoad Side Flow See E: Noisy blower and low air fl ow.

I: WATER DRIPPING FROM UNITUnit not level Level unit.

Condensation drain line plugged Unplug condensation line.

Water sucking off the air coil in cooling mode

Too much airfl ow. Duct work not completely installed. If duct work is not completely installed, fi nish duct work. Check static pressure and compare with air fl ow chart in spec manual under specifi c models section. If ductwork is completely installed it may be necessary to reduce CFM.

Water sucking out of thedrain pan

Install an EZ-Trap or P-Trap on the drain outlet so blower cannot suck air back through the drain outlet.



A: Check all terminals, wires & connections for loose or burned wires and connections. Check contactor and 24 Volt coil. Check capacitor connections & check capacitor with capacitor tester.

B: If ohm meter reads 0 (short) resistance from C to S, S to R, R to C or from anyone of one of these terminals to ground (shorted to ground), compressor is bad.

J: COMPRESSOR WON’T START

K: COMPRESSOR WON’T PUMP CHART

Equipment Start-Up Process

Check the following before power is applied to the equipment Caution: Do not start-up the unit until the new structure is ready to be occupied

Electrical: Geothermal unit high voltage

wiring is installed correctly Geothermal unit high voltage

wiring and breaker are the correct size

Auxiliary electric heaters are wired and installed correctly

Circulating pumps are wired and fused (if necessary) correctly

Desuperheater pump is NOT wired, unless piping is complete and all air is purged

Low voltage wiring is correct and completely installed

Equipment Start-Up

1. Energize geothermal unit with high voltage.

2. Set the thermostat to “Heat” or “Cool.” Adjust set point to energize the unit. System will energize after delays expire (typically a five minute delay).

3. Check water flow with a flow meter (non-pressurized) or pressure drop conversion (pressurized). Pressure drop tables must be used to convert the pressure drop to GPM. The pressure drop can be obtained by checking water pressure in and water pressure out at the P/T ports.

4. Check the geothermal unit’s electrical readings listed in the Unit Electrical Data table.

5. Check the source water temperature in and out at the P/T ports (use insertion probe). Allow 10 minutes of operation before recording temperature drop.

6. Calculate the heat of extraction or heat of rejection.

Plumbing: Pipe and pump sizes are correct Air is purged from all lines Antifreeze is installed All valves are open, including

those on the flow center Condensate is trapped and piped

to the drain Ductwork:

Filter is installed and clean Packaging is removed from the

blower assembly Blower turns freely Canvas connections installed on

supply plenum & return drop

7. Check the temperature difference of the load coax (water-to-water) or air coil (water-to-air). P/T ports are recommended for use on the load side, but the line temperatures can be used to check the temperature difference.

8. Change the mode of the thermostat and adjust the set point to energize the unit. Check the data in opposite mode as the previous tests. Amp draws as well as temperature differences and flow rate should be recorded.

9. Check auxiliary heat operation by adjusting the thermostat set point 5°F above the room temperature in “Heat” mode or set thermostat to “Emergency." Record voltage, amperage, and air temperature difference.
