Features/BenefitsEvery compact one-piece unit arrives fully assembled, charged, tested, and ready to run.Quiet, efficient operation and dependable performanceCompressors have vibration isolators for quiet operation. Efficient fan and motor design permits operation at low sound levels.
Unit sizes 008-028 offer lower utility costs through part-load operation using 2 or 3 stages of cooling.
Quiet and efficient operation is provid-ed by belt-driven evaporator fans (stan-dard on all units over 5 tons). The belt-driven evaporator-fan is equipped with variable-pitch pulleys which allow adjust-ment within the rpm ranges of the factory-supplied pulleys.
Increased operating efficiency is achieved through computer-designed coils featuring staggered internally enhanced copper tubes. Fins are ripple-edged for strength, lanced, and double waved for higher heat transfer.
Durable, dependable constructionDesigned for durability in any climate, the weather-resistant cabinets areconstructed of galvanized steel and bond-
erized, and all exterior panels are coated with a prepainted baked enamel finish. The paint finish is non-chalking, and is capable of withstanding ASTM (Ameri-can Society for Testing andMaterials) B117 500-hour Salt Spray Test. All internal cabinet panels are primed, permitting longer life and a more attractive appearance for theentire unit.
In addition, all size 003-014 units are designed with a single, continuous top piece to eliminate any possible leaks at seams or gasketing. Totally enclosed con-denser-fan motors and permanently lubri-cated bearings provide additional unit de-pendability.Easy installation and conversionAll units are shipped in the vertical duct configuration for fit-up to standard roof curbs. The contractor can order and install the roof curb early in the construc-tion stage, before decisions on size re-quirements are made.
All units feature a base rail design with forklift slots and rigging holes for easier maneuvering. Durable packaging pro-tects all units during shipment and stor-age.
The units can be easily converted from a vertical to a horizontal duct configura-tion by relocating the panels
supplied with the unit (sizes 003-014 only).To convert size 003-014 units from verti-cal to horizontal discharge, simply relo-cate 2 panels. The same basic unit can be used for a variety of applications and can be quickly modified at the jobsite.To convert size 015-028 units from verti-cal to horizontal discharge, use the op-tional horizontal supply/return adapter roof curb (50HJ015-017) or accessory conversion kit (020-028).Convenient duct openings in the unit basepans permit side-by-side or concen-tric duct connections (seeApplication data section) without requir-ing internal unit modification.NOTE: On units using horizontal sup-ply and return, the accessory barometric relief or power exhaust MUST be installed on the return ductwork.Thru-the-bottom service connection ca-pability comes standard with the rooftop unit to allow power and control wiring to be routed through the unit’s basepan, minimizing roof penetrations (003-014 units requier a thru-the-bottom accessory kit to prevent water leaks). Power and control connections are made on the same side of the unit to simplify installation.The non-corrosive sloped condensate drain pan (size 003-014) permits either an external horizontal side

condensate drain (outside the roof curb) or an internal vertical bottom drain (inside the roof curb). Both options require an external, field-supplied P-trap.Standard 2-in. throwaway filters are easily accessed through a removable pan-el located above the air intake hood. No tools are required to change unit filters.Belt-driven evaporator-fan motors al-low maximum on-site flexibility without changing motors or drives.Field-installed accessory electric heat-ers are available in a wide range of capac-ities. An available single-point wiring kit makes installation simple.Low voltage wiring connections are eas-ily made thanks to the large terminal board which is located for quick, conve-nient access.
In addition, color-coded wires permit easy tracing and diagnostics.
Proven compressor reliabilityDesign techniques feature computer-pro-grammed balance between compressor, condenser, and evaporator. Carrier-speci-fied hermetic compressors are equipped with compressor overcurrent and over-temperature protection to ensure depend-ability.
All units have Carrier’s exclusiveAcutrol™ (003-014) or TXV (thermostat-ic expansion valve) metering device (015-028) which precisely controls refrigerant flow, preventing slugging and flood-back, while maintaining optimum unit perfor-mance. Refrigerant filter driers are stan-dard.
Integrated economizers and out-door-air dampersAvailable as options or accessories, econ-omizers and manual outdoor-air dampers introduce outdoor air which mixes with the conditioned air, improving indoor-air quality and often reducing energy con-sumption.
During a first stage call for cooling, if the outdoor-air temperature is below the economizer control changeover set point, the mixed-air sensor modulates the economizer outdoor-air damper open to take advantage of free cooling provided by the outside air. When second-stage cooling is called for, the compressor is en-ergized in addition to the economizer. If the outdoor-air temperature is above the changeover set point, the first stage of compression is activated and the econ-omizer damper stays at minimum posi-tion.
Accessory upgrade kits allow for control by differential dry-bulb tempera-
ture (outdoor vs return), outdoor air en-thalpy changeover, or more precise differ-ential enthalpy control.
Units can be equipped with different economizer options to meet specific con-trols applications. The factory-installed or field-installed EconoMi$er IV and EconoMi$er2 are available. The EconoMi$er IV is used with the standard rooftop unit controls and includes an in-dustry standard, stand-alone,solid-state control. The control can be used with a CO2 sensor for DCV (demand control ventilation) operation. For direct digital control (DDC) applications, the EconoMi$er2 can be operated using Pre-mierLink™ controls or a third party con-troller. The EconoMi$er2 includes 4 to 20 mA actuator capability for demand con-trol ventilation applications.
All economizers incorporate a parallel blade, gear-driven damper system for effi-cient air mixing and reliablecontrol. In addition, the standard damper actuator includes a springreturn to provide reliable closure on pow-er loss. The economizers for sizes 003-014 are equipped with up to 100% baro-metric relief capability for high outdoor airflow operations. Economizers for unit sizes 003-014 are available, factory-in-stalled, for vertical return only. Economiz-ers for unit sizes 015-028 are compatible for vertical or horizontal return. An op-tional field-installed barometric relief package is available for 015-028 size units.
In addition, single-stage power exhaust is available as a field-installed accessory for EconoMi$er IV to help maintain proper building pressure.
For units without economizer, year-round ventilation is enhanced by a manual outdoor-air damper. On size 003-014 units, a 25% or 50% manual damper is available as a field-installed accessory. Unit sizes 015-028 are equipped with a manual 25% damper.
Service optionsServicing a rooftop unit has never been easier with the new factory- installed ser-vice options for these rooftop units. These options include the following:• Hinged access panels are provided for
the filter/indoor-fan motor, compres-sors, evaporator fan, and control box areas. Quick access to major compo-nents is accomplished by simply unlatching and swinging open the vari-ous panels. Each hinged panel is per-manently mounted to the unit, thereby eliminating the concern of a dropped or wind-blown panel puncturing deli-cate roof materials. The 4 extended access panels are also equipped with ‘‘tie back’’ retaining devices to hold
the door in the open position while ser-vicing the unit.
• An external, covered, 115-v Ground Fault Interrupt (GFI) receptacle is pro-vided as a convenient power source for drills, lights, refrigerant recovery units, or other electrical service tools. A fac-tory-supplied step down transformer is connected to the “load” side of the unit main power connection (size 003-014). For sizes 015-028, connect the outlet to a field-supplied and properly fused branch circuit power supply.
• Slide out “motor-drive-blower”reduces service time (only on 50HJ017).
• An integral non-fused disconnect switch within the rooftop unit reduces installation time, labor and material costs. Safety is assured by an interlock which prevents access to the control box unless the switch is in the OFF position. In addition, the externally mounted handle incorporates power lockout capability to further protect service personnel.
Carrier PremierLink™ controls add reliability, efficiency, and sim-plificationThe PremierLink direct digital controls can be ordered as a factory-installed op-tion (003-014 only) or as a field-installed accessory (003-028). Designed and man-ufactured exclusively by Carrier, the con-trols can be used to actively monitor and control all modes of operations, as well as monitor the following diagnostics and features: unit number, zone temperature, zone set point, zone humidity set point,discharge air temperatures, fan status, stages of heating, stages of cooling, damper position, outdoor-air tempera-ture, outdoor humidity level, filter status, fire shutdown status, IAQ (indoor air quality) set point, enthalpy status, differ-ential enthalpy status, heat/cool lockout, cfm set point, pre-occupancy purge, econ-omizer controls and early morning warm-up.
This controller has a 38.4K baud com-munications capability and is compatible with ComfortLink™ Controls, CCN (Car-rier Comfort Network®) and Comfort-VIEW™ Software. The Scrolling Mar-quee and Navigator™ device are optional tools that can be used for programming and monitoring the unit for optimal per-formance. The addition of the Carrier CO2 sensor in the conditioned space pro-vides ASHRAE 62.1 (American Society of Heating, Refrigeration and Air Condi-tioning Engineers) compliance and De-mand Control Ventilation.
The PremierLink™ peer-to-peer,Internet ready communicating control is
4
designed specifically for Constant Volume (CV) and Variable Volume and Tempera-ture (VVT®) applications. This compre-hensive controls system allows all Carrier rooftops with a 3-wire communication bus to be daisy chained together on a roof to create a fully functional HVAC (heating, ventilation, and air conditioning) automa-tion system.
Indoor-air quality begins with Car-rier rooftopsSloped condensate pans minimize biological growth in rooftop units inaccordance with ASHRAE Standard 62. Two-inch filters with optional dirty filter indicator switch provide for greater particle reduction in the return air. The face-split evaporator coils improve the dehumidification capability of standard units, maximize building hu-midity control.
Optional proportional reacting CO2 sensor is available with the EconoMi$er IV or EconoMi$er2 outdoor air damper option or accessory to aid the IAQ benefits.
Humidi-MiZer™ adaptive dehu-midification system (003-014)Carrier’s Humidi-MiZer adaptive dehu-midification system is an all-inclusive fac-tory-installed option that can be ordered with any Weathermaster® 50HE003-006 and 50HJ004-014 rooftop unit to meet the demand for providing a flexible and high performing solution to accommodate all of these design related issues. This system expands the envelope of operation of Car-rier’s Weathermaster 50HJ003-014 roof-top products to provide unprecedented flexibility to meet year round comfort conditions. The Humidi-MiZer adaptive dehumidification system has the indus-try’s only dual dehumidification mode set-
ting. The Humidi-MiZer system includes two new modes of operation. The Weath-ermaster rooftop coupled with the Humi-di-MiZer system is capable of operating in normal design cooling mode, subcooling mode, and hot gas reheat mode. Normal design cooling mode is when the unit willoperate under its normal sequence of oper-ation by cycling compressorsto maintain comfort conditions.Subcooling mode will operate to satisfy part load type conditions when the space requires combined sensible and a higher proportion of latent load control. Hot Gas Reheat mode will operate when outdoor temperatures diminish and the need for la-tent capacity is required for sole humidity control. Hot Gas Reheat mode will pro-vide neutral air for maximum dehumidifi-cation operation.
COBRA™ energy recovery units (50HE003-006 and 50HJ004-014 only)Carrier’s factory-installed optionalCOBRA units recover energy from the building exhaust air and precondition ventilation air for the rooftop unit during winter and summer operation. These units are designed to satisfy the higher ventila-tion requirements and other building codes while minimizing energy costs.
Factory installation of the 62AQ sec-tion provides the benefit of reduced field-installation time, single point power con-nections, and the assurance of a factory test for the complete COBRA unit. The COBRA energy recovery section re-quires less maintenance than other energy recovery systems and can be serviced by any qualified refrigeration technician.
The COBRA energy recovery units uti-lize Carrier’s high-efficiency 50HE003-006 or 50HJ004-014 rooftop units and
provide 2 to 121/2 tons of cooling capacity with the capability to pre-condition 600 to 3000 cfm of outdoor air.
Indoor-air quality (IAQ) generallyrefers to the level of pollutants inside a building. These pollutants include ciga-rette smoke, carbon dioxide exhaled by occupants, radon gas, car exhaust, paint fumes, and odors.
Concern over increased indoor air pol-lutants has been spurred by several issues: 1) changes in new building construction methods and retrofit of older buildings have reduced air infiltration rates; 2) Synthetic materials release airborne particles, odors, and chemicals; and 3) HVAC (heating, ventilation, and air conditioning) systems that bring in mini-mal fresh air.
In 1989, IAQ concerns caused ASHRAE to recommend increased venti-lation for all public buildings. Simply introducing fresh air into a build-ing, however, is not always practical or cost effective. Additional ven-tilation can overload HVAC systems and increase energy costs.
Carrier’s COBRA energy recovery unit solves this dilemma by providing in-creased fresh air while keeping increased costs to a minimum. In addition, the COBRA energy recovery unit helps reduce humidity levels, which helps to prevent deterioration of building materials and retards the growth of mold and mildew.
The COBRA energy recovery unit pro-vides the best solution to retaining the en-ergy-conserving benefits of today’s tight-er building construction while improving indoor-air quality.

II Determine fan speed and power requirements atdesign conditions.Before entering the Fan Performance tables, calculatethe total static pressure required based on unit compo-nent. From the given and the Accessory Electric HeatersStatic Pressure table on page 101 find:External static pressure supply 0.6 in. wgExternal static pressure return 0.2 in. wgAccessory static electric heater 0.11 in. wgTotal Static 0.9 in. wgEnter the Fan Performance table for vertical discharge,50HJ006 (page 66) at 0.90 in. wg. At 2000 cfm the rpmis 1264 and bhp is 1.44 (interpolation required).NOTE: Convert bhp to Fan Heat and Watts using theformula found in the note following the Evaporator-FanMotor Efficiency table on page 194.For this example:Watts = (746 x Bhp)/(motor efficiency)Watts = (746 x 1.44)/(0.84) = 1279 wattsIndoor Fan Heat = watts x 3.413 Btuh/watt
= 1279 x 3.413= 4365 Btuh
III Select Energy$Recycler unit based on OutdoorEntering Cfm (optional).Entering Energy$Recycler cooling rating table in theEnergy$Recycler Product Data literature at 450 cfmentering outdoor airflow. Choose Model 62AQ060.Using 450 cfm outdoor supply airflow, 95 F OD db, and75 F OD wb find performance of the 62AQ060 at theseconditions:Energy$Recycler Gross Cooling
Capacity is 13,000 BtuhEnergy$Recycler Gross Sensible
Capacity is 10,090 BtuhCompressor power is 1.06 kWEnergy$Recycler Leaving db is 73 FEnergy$Recycler Leaving wb is 66.9 F
IV Using the simplified* method below, calculate theapproximate mixed air temperature for the SmallRooftop (SRT) evaporator coil.Using the outdoor-air entering cfm, the room cfm andthe room exhaust airflow with their respective db andwb temperatures, determine the db and wb entering therooftop evaporator coil.a) Estimate the mixed air db to the evaporator coil.
t mix db = ((cfm oa x t oa db) + ((cfm ra – cfm exh) xt ra db)) / ((cfm oa + (cfm ra – cfm exh)))= ((450 cfm x 73.0 F) + ((2000 cfm – 450 cfm) x 78 F)) / ((450 cfm + (2000 cfm – 450 cfm)))Mixed air into the rooftop evaporator coil = 76.9 F db
b) Estimate the mixed air wb to the evaporator coil.t mix wb* = ((cfm oa x t oa wb) + ((cfm ra – cfmexh) x t ra wb)) / (cfm oa + (cfm ra – cfm exh))= ((450 cfm x 66.9 F) + ((2000 cfm – 450 cfm) x 65 F)) / ((450 cfm + (2000 cfm – 450 cfm)))Mixed air temperature into the rooftop evaporator =65.4 F wb*Simplified method of determining wet bulb (wb) tem-
perature of mixture. This approximation is usedbecause the wb lines in the area of the psychrometricchart used in the calculation is relatively linear, pro-viding a close approximation. A more accurate solu-tion can be found using the E-Cat program.

V Determine the cooling load requirement for the roof-top unit.Customer load is 67,000 BtuhLess TC supplied by the
Energy$Recycler –13,000 BtuhRooftop cooling load required is 54,000 Btuh
VI Select the rooftop unit based on mixed air enteringconditions and cooling load.Enter cooling capacity table at outdoor entering temper-ature 95 F, mixed air entering evaporator at 2000 cfm,76.9 F db, and 65.4 F wb.The 50HJ006 will provide a total gross cooling capacityof 59,420 Btuh and sensible cooling of 43,420 Btuh.Because these values were not at 80 F entering db, theywere calculated based on the notes following the Cool-ing Capacity tables.NOTE: Unit ratings are gross capacities and do notinclude the effect of evaporator-fan motor heat. To cal-culate net capacities see Steps VII and VIII.
VII Select net heating capacity of unit to meet designcondition requirements.Enter the 62AQ060 Heating rating table at 450 cfm. At70 F and 0° F find the heating value for theEnergy$Recycler to be 15.2 MBtuh. Since theEnergy$Recycler uses room air, the instantaneous heatis also the Integrated Heat Rating.The customer heat requirement is 50,000 Btuh.Fan heat from Step II 4,365 Btuh

There-fore, 30,435 Btuh (50,000 – 19,565) additional heat isrequired.Determine additional electric heat in kW.(30,435/3413 Btuh/kW) = 8.92 kW of heat is required.Enter Electric Heating Usage tables, page 109, for50HJ006 at 208/230, 3 phase. The 10.5 kW heater at240 v most closely satisfies the heating required. To cal-culate kW at 230 v use the Multiplication Factors table.10.5 kW x 0.92 = 9.668 kW10.5 kW x 0.92 x 3413 Btuh/kW = 32,970 BtuhTotal unit net heating capacity is 52,535 Btuh (32,970 +19,565).
VIII Determine net cooling capacity.Cooling capacities are gross capacities and do notinclude in do or (evaporator)or optional Energy$Recy-cler supply fan heat.Determine net cooling capacity using the following for-mula:Net Capacity = (Gross Capacity Rooftop Unit +Energy$Recycler) – (IFM Heat + OptionalEnergy$Recycler Supply Fan motor heat)Gross Total Cooling

X Electrical data RLA, FLA, LRA, MCA and MOCP.Separate Power Supply:If the 62AQ is wired for separate power see the Electri-cal Data table.Single Power Supply with Unit:The unit is 230 v-3-60 Hz. Look up the 50HJ006 with-out convenience outlet in the Electrical Data table andwith a 10.5 kW heater, find unit electrical data. For therooftop unit the data is MCA = 38.8 amps, MOCP = 40, Min Unit Disconnect Size FLA = 36, andLRA = 168.From the Table of “X” and “Y” values in theEnergy$Recycler Product Data literature find 230 v, for62AQ060300, “X” = 8.1 amps and “Y” = 9.3 amps.Add “X” amps to the MCA and MOCP and add “Y”amps to the minimum disconnect size.
**The calculated MOCP is 48.1 amps; it is rounded down to 40amps. Compare it to MCA; it must be larger than the MCA of46.9 amps, so it is rounded up 50 amps.
The wiring of the unit must be suitable for the MCA cal-culated above, and the maximum overcurrent protection(MOCP) device must be selected to meet the calculatedMOCP.If the overcurrent protective device for the combinationload is equal to or less than 60 amps, a single disconnectmay be used for BOTH the main unit and the 62AQ pro-vided that the wire ampacity supplying the 62AQ issized for a minimum of 33% larger than the overcurrentprotection device value (i.e., 60 amps x 0.33 = 20amps), no further subfusing would be required.If the overcurrent protection device is greater than 60amps and the old overcurrent protection device was lessthan 60 amps, a FUSED disconnect no greater than 60amps must be provided for the Main Unit and a SEPA-RATE FUSED disconnect must be provided for the62AQ unit.If the old overcurrent protection device is greater than60 amps, a disconnect is required for the MAIN UNITas well as a FUSED DISCONNECT for the 62AQ unit.In this example a 50-amp disconnect would be used forthe combination load of the 50HJ006 with a 10.5 kWheater and the 62AQ060 Energy$Recycler unit.

NOTES:1. Direct interpolation is permissible. Do not extrapolate.2. The following formulas may be used:
tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving evapo-rator coil (hlwb)
Where: hewb = Enthalpy of air entering evaporator coil3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.Above 80 F edb, add (corr factor x cfm) to SHC.
Interpolation is permissible.Correction Factor = 1.10 x (1 – BF) x (edb – 80).

GENERAL FAN PERFORMANCE NOTESNOTES:
1. Values include losses for filters, unit casing, and wet coils. Seepages 102-105 for accessory/factory-installed option static pres-sure information.
2. Extensive motor and electrical testing on these units ensures thatthe full range of the motor can be utilized with confidence. Usingyour fan motors up to the wattage ratings shown will not result innuisance tripping or premature motor failure. Unit warranty will not
be affected. See Evaporator-Fan Motor Performance tables onpages 96-99 for additional information.
3. Use of a field-supplied motor may affect wire sizing. Contact yourCarrier representative for details.
4. Interpolation is permissible. Do not extrapolate.5. Field-supplied drive requires changing belt and motor pulley to
meet desired air flow. See application data or contact your localCarrier representative for details.

*Single-phase/3-phase.NOTES:1. Convert watts to bhp using the following formula:
2. The EPACT (Energy Policy Act of 1992) regulates energy require-ments for specific types of indoor fan motors. Motors regulated byEPACT include any general purpose, T-frame (three-digit, 143 andlarger), single-speed, foot mounted, polyphase, squirrel cage induc-tion motors of NEMA (National Electrical Manufacturers Association)design A and B, manufactured for use in the United States. Rangingfrom 1 to 200 Hp, these continuous-duty motors operate on 230 and460 volt, 60 Hz power. If a motor does not fit into these specifica-tions, the motor does not have to be replaced by an EPACT- compli-ant energy-efficient motor. Variable-speed motors are exempt fromEPACT compliance requirements. Therefore, the indoor fan motorsfor Carrier 50HJ004-014 units are exempt from these requirements.
EVAPORATOR-FAN MOTOR EFFICIENCY — 50HJ015,017
NOTE: All indoor-fan motors 5 hp and larger meet the minimum effi-ciency requirements as established by the Energy Policy Act of 1992(EPACT) effective October 24, 1997.
Field-Supplied DriveWhere "field supplied drive" is indicated, the factory supplied pulley and belt combination must be changed to achieve the desired fan rpm. Beltsizing must be obtained based on desired pulley size. To calculate the necessary pulley size, use the following formula: D2 = D1 * (RPM2)/(RPM1)where:D2 = new motor pulley diameterD1 = existing median pulley diameterRPM2 = desired blower RPMRPM 1 = median blower RPM

†Heater capacity (kW) is based on heater voltage of 240 v, 480 v or 575 v. If power distributionvoltage to unit varies from rated heater voltage, heater kW will vary accordingly.
*The values listed in this table do not include power exhaust. See power exhaust table forpower exhaust requirements.
** Fuse or HACR breaker.NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse orHACR breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Usethe following formula to determine the percent of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. Non-fused disconnect switch cannot be used when rooftop unit electrical ratings exceed80 amps.
4. 575-v units have UL, Canada approval only. Electric heaters are not available for 004-007,575-v units.
5. For units with power exhaust: If a single power source is to be used, size wire to includepower exhaust MCA and MOCP.Check MCA and MOCP when power exhaust is powered through the unit. Determine thenew MCA including the power exhaust using the following formula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 50HE/HJ006---5 unit with MCA = 28.9 and MOCP = 35, withCRPWREXH030A01 power exhaust.MCA New = 28.9 amps + 1.6 amps = 30.5 ampsIf the new MCA does not exceed the published MOCP, then MOCP would not change. TheMOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP isacceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the nextlarger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC

†Heater capacity (kW) is based on heater voltage of 240 v, 480 v or 575 v. If power distributionvoltage to unit varies from rated heater voltage, heater kW will vary accordingly.
*The values listed in this table do not include power exhaust. See power exhaust table forpower exhaust requirements.
** Fuse or HACR breaker.NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse orHACR breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Usethe following formula to determine the percent of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. Non-fused disconnect switch cannot be used when rooftop unit electrical ratings exceed80 amps.
4. 575-v units have UL, Canada approval only. Electric heaters are not available for 004-007,575-v units.
5. For units with power exhaust: If a single power source is to be used, size wire to includepower exhaust MCA and MOCP.Check MCA and MOCP when power exhaust is powered through the unit. Determine thenew MCA including the power exhaust using the following formula:MCA New = MCA unit only + MCA of Power ExhaustFor example, using a 50HJ006---5 unit with MCA = 28.9 and MOCP = 35, withCRPWREXH030A01 power exhaust.MCA New = 28.9 amps + 1.6 amps = 30.5 ampsIf the new MCA does not exceed the published MOCP, then MOCP would not change. TheMOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP isacceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the nextlarger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC

†Heater capacity (kW) is based on heater voltage of 240 v, 480 v or 575 v. If power distributionvoltage to unit varies from rated heater voltage, heater kW will vary accordingly.
*The values listed in this table do not include power exhaust. See power exhaust table forpower exhaust requirements.
** Fuse or HACR breaker.NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse orHACR breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Usethe following formula to determine the percent of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 vBC = 464 vAC = 455 v
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

†Heater capacity (kW) is based on heater voltage of 240 v, 480 v or 575 v. If power distributionvoltage to unit varies from rated heater voltage, heater kW will vary accordingly.
*The values listed in this table do not include power exhaust. See power exhaust table forpower exhaust requirements.
** Fuse or HACR breaker.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equip-
ment (refer to NEC Articles 430 and 440), the overcurrent protective device for theunit shall be fuse or HACR breaker. UL, Canada units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than2%. Use the following formula to determine the percent of voltage imbalance.
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable2%.

†Heater capacity (kW) is based on heater voltage of 240 v, 480 v or 575 v. If power distributionvoltage to unit varies from rated heater voltage, heater kW will vary accordingly.
*The values listed in this table do not include power exhaust. See power exhaust table forpower exhaust requirements.
** Fuse or HACR breaker.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equip-
ment (refer to NEC Articles 430 and 440), the overcurrent protective device for theunit shall be fuse or HACR breaker. UL, Canada units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than2%. Use the following formula to determine the percent of voltage imbalance.
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable2%.

†Heater capacity (kW) is based on heater voltage of 240 v, 480 v or 575 v. If power distributionvoltage to unit varies from rated heater voltage, heater kW will vary accordingly.
*The values listed in this table do not include power exhaust. See power exhaust table forpower exhaust requirements.
** Fuse or HACR breaker.NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse orHACR breaker. UL, Canada units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Usethe following formula to determine the percent of voltage imbalance.
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x = 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

†Heater capacity (kW) is based on heater voltage of 240 v, 480 v or 575 v. If power distributionvoltage to unit varies from rated heater voltage, heater kW will vary accordingly.
*The values listed in this table do not include power exhaust. See power exhaust table forpower exhaust requirements.
** Fuse or HACR breaker.NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse orHACR breaker. UL, Canada units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Usethe following formula to determine the percent of voltage imbalance.
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
= 457Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x = 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

ELECTRIC HEAT BRANCH CIRCUIT 208/240 75-kW ELECTRIC HEAT†
FEEDER CIRCUIT FOR 208/230 UNIT WITH 75-kW ELECTRIC HEAT†
LEGEND
*Fuse or HACR circuit breaker.†208/230 v 75-kW Electric Heat units must use dual-point wiring. The main table lists the
branch circuit values for the refrigeration part of the system. The following two tables list thebranch circuit values for the electric heat and values for a feeder circuit for both branch cir-cuits.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse orHACR breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Usethe following formula to determine the percent of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. The 75-kW 208/240-v electric heat can be factory installed but it must be wired separately inthe field.
4. The convenience outlet full load amps (FLA) are 5, 3 and 3 for 208/230, 460, 575-v units,respectively.
5. The FLA load amps provided in the table for electric heaters are based on 208/240, 480 and600 v.
6. MCA calculation for 50HJ units with electric heaters over 50 kW is = 1.25 x (IFM + PowerExhaust + Convenience Outlet FLA amps) + 1.00 x (Electric Heater FLA).

ELECTRIC HEAT BRANCH CIRCUIT 208/240 75-kW ELECTRIC HEAT†
FEEDER CIRCUIT FOR 208/230 UNIT WITH 75-kW ELECTRIC HEAT†
LEGEND
*Fuse or HACR circuit breaker.†208/230 v 75-kW Electric Heat units must use dual-point wiring. The main table lists the
branch circuit values for the refrigeration part of the system. The following two tables list thebranch circuit values for the electric heat and values for a feeder circuit for both branch cir-cuits.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse orHACR breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Usethe following formula to determine the percent of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. The 75-kW 208/240-v electric heat can be factory installed but it must be wired separately inthe field.
4. The convenience outlet full load amps (FLA) are 5, 3 and 3 for 208/230, 460, 575-v units,respectively.
5. The FLA load amps provided in the table for electric heaters are based on 208/240, 480 and600 v.

FEEDER CIRCUIT FOR 208/230 UNIT WITH 75-kW ELECTRIC HEAT†
LEGEND
*Fuse or HACR circuit breaker.†208/230 v 75-kW Electric Heat units must use dual-point wiring. The main table lists the
branch circuit values for the refrigeration part of the system. The following two tables list thebranch circuit values for the electric heat and values for a feeder circuit for both branch cir-cuits.
NOTES:1. In compliance with NEC requirements for multimotor and combination load equipment (refer
to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse orHACR breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply voltage is greater than 2%. Usethe following formula to determine the percent of voltage imbalance.% Voltage Imbalance
Example: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v
Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v(BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
Maximum deviation is 7 v.Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
3. The 75-kW 208/240-v electric heat can be factory installed but it must be wired separately inthe field.
4. The convenience outlet full load amps (FLA) are 5, 3 and 3 for 208/230, 460, 575-v units,respectively.
5. The FLA load amps provided in the table for electric heaters are based on 208/240, 480 and600 v.
6. MCA calculation for 50HJ units with electric heaters over 50 kW is = 1.25 x (IFM + PowerExhaust + Convenience Outlet FLA amps) + 1.00 x (Electric Heater FLA).

PremierLink™ Direct Digital Controls — The PremierLinkDirect Digital Controls (DDC) require the use of a Carrier elec-tronic thermostat or a CCN connection for time broadcast toinitiate its internal timeclock. This is necessary for broadcast oftime of day functions (occupied/unoccupied). Refer to Premier-LinkTM literature for more informationPremierLink Features:• Equipment Control Functions

Indoor Air Quality (IAQ) Monitoring — An indoor air qual-ity (IAQ) controller will maintain indoor air quality within thespace at the set point level. The set point is calculated from thedifferential air quality that is configured by the user. As airquality within the space changes, the position of the econo-mizer damper will also change thus allowing more or less out-door air into the space. If IAQ is configured for low priority, thepositioning of the economizer damper can be overridden bycomfort requirements. If IAQ is configured for high priority,the controller will check the air quality every 30 seconds andwill perform supply air tempering when in IAQ mode if the fol-lowing criteria are met:• IAQ priority is high• Outdoor temperature is less than 55 F• Heat and cool set points have not been exceededDemand Control Ventilation — Certain criteria must be con-sidered when using the PremierLink™ controller for demandcontrol ventilation. When selecting the heating and coolingcapacity of the equipment, the maximum ventilation rate mustbe evaluated for design conditions along with the maximumdamper position to achieve desired conditioning of the space.Typical maximum ventilation rate should be ASHRAE occu-pied design cfm +5 to 10%. The PremierLink controller can also provide tempering of thesupply air when the space or return air temperature falls be-tween the occupied heat and cool set points or there is not a callfor heating or cooling in the Thermostat mode. The maximumventilation airflow rate should be checked by evaluating theunit’s heating capability to raise the supply air to an acceptablelevel during tempering of supply air. After determining the maximum ventilation airflow rate theIAQ maximum damper configuration needs to be configured.Demand control ventilation software may be used to assist indetermining the CO2 maximum ventilation recovery rate. Therecovery rate can be accomplished by using either proportion-al-anticipatory strategy or proportional integral (PI) control.

Operating sequence, 50HE003-006 and 50HJ 004-014 unitsCooling, units without economizer — When thermostat callsfor cooling, terminals G and Y1 are energized. The indoor(evaporator) fan contactor (IFC) and compressor contactor no.1 (C1) are energized, and evaporator-fan motor (IFM), com-pressor no. 1, and condenser fan(s) start. The liquid line sole-noid valve for compressor no. 1 is de-energized open. The con-denser-fan motor(s) runs continuously while unit is cooling.For units with 2 stages of cooling, if the thermostat calls for asecond stage of cooling by energizing Y2, compressor contac-tor no. 2 (C2) is energized and compressor no. 2 starts.Heating, units without economizer (units with electric heat)— Upon a call for heating through W1, indoor (evaporator) fancontactor (IFC) and heater contactor no. 1 (HC1) are energized.On units equipped for 2 stages of heat, when additional heat isneeded, heater contactor no. 2 is energized through W2.Cooling, units with EconoMi$er IV — When free cooling isnot available, the compressors will be controlled by the zonethermostat. When free cooling is available, the outdoor-airdamper is modulated by the EconoMi$er IV control to providea 50 to 55 F mixed-air temperature into the zone. As the mixed-air temperature fluctuates above 55 or below 50 F, the damperswill be modulated (open or close) to bring the mixed-air tem-perature back within control.
If mechanical cooling is utilized with free cooling, the out-door-air damper will maintain its current position at the timethe compressor is started. If the increase in cooling capacitycauses the mixed-air temperature to drop below 45 F, then theoutdoor-air damper position will be decreased to the minimumposition. If the mixed-air temperature continues to fall, the out-door-air damper will close. Control returns to normal once themixed-air temperature rises above 48 F.
If optional power exhaust is installed, as the outdoor-airdamper opens and closes, the power exhaust fans will be ener-gized and deenergized.
If field-installed accessory CO2 sensors are connected to theEconoMi$er IV control, a demand controlled ventilation strate-gy will begin to operate. As the CO2 level in the zone increasesabove the CO2 set point, the minimum position of the damperwill be increased proportionally. As the CO2 level decreasesbecause of the increase in fresh air, the outdoor-air damper willbe proportionally closed.
For EconoMi$er IV operation, there must be a thermostatcall for the fan (G). If the unit is occupied and the fan is on, thedamper will operate at minimum position. Otherwise, thedamper will be closed.
When the EconoMi$er IV control is in the occupied modeand a call for cooling exists (Y1 on the thermostat), the controlwill first check for indoor fan operation. If the fan is not on,then cooling will not be activated. If the fan is on, then the con-trol will open the EconoMi$er IV damper to the minimum po-sition.
On the initial power to the EconoMi$er IV control, it willtake the damper up to 21/2 minutes before it begins to positionitself. Any change in damper position will take up to 30 sec-onds to initiate. Damper movement from full closed to fullopen (or vice versa) will take between 11/2 and 21/2 minutes.
If free cooling can be used as determined from the appropri-ate changeover command (switch, dry bulb, enthalpy curve,differential dry bulb, or differential enthalpy), then the controlwill modulate the dampers open to maintain the mixed-air tem-perature set point at 50 to 55 F.
If there is a further demand for cooling (cooling second stage— Y2 is energized), then the control will bring on compressorstage 1 to maintain the mixed-air temperature set point. TheEconoMi$er IV damper will be open at maximum position.EconoMi$er IV operation is limited to a single compressor.Heating, units with EconoMi$er IVNOTE: The units have 2 stages of electric heat.
When the thermostat calls for one stage of heating, W1 is ener-gized. The thermostat must be configured such that the bloweroutput (G) is energized when there is a W1 call for heating. Theindoor fan contactor (IFC) and first stage electric heat contac-tor(s) are energized, and the indoor-fan motor and first stage elec-tric heater are started. The EconoMi$er IV damper modulates tothe minimum position.
If additional heating is required, the thermostat will call for asecond stage of heating, energizing W2. This will energize thesecond stage of electric heat. The EconoMi$er IV damper mod-ulates to the minimum position.

If all of the above conditions are met, the number of heatstages is calculated; otherwise the required number of heatstages will be set to 0.
If the PremierLink controller determines that heat stages arerequired, the economizer damper will be moved to minimumposition if occupied and closed if unoccupied.Operating Sequence COBRA units — (See COBRA/62AQApplication Data for additional information.)Cooling, units with COBRA™ energy recovery — The cool-ing changeover thermostat located on COBRA energy recoveryunit hood determines when the COBRA energy recovery unitgoes into economizer mode. When the outdoor temperature isbelow the cooling set point the unit will be in economizermode.
In the unoccupied mode, fans are normally set for AUTOoperation, causing the fans to cycle on only as needed for heat-ing or cooling. If the Thermidistat™ device is set for “AUTO”fan, the rooftop unit fan will be off except when cooling orhumidity control is required. The COBRA energy recovery unitfans will be off except when unit is running in the economizermode. If the Thermidistat fan setting is set to “ON”, theCOBRA energy recovery unit and rooftop unit fans will runcontinuously. If outdoor air is below the outdoor air thermostatset point, the compressors are locked off and the unit operatesin economizer mode when cooling is required. If outdoor air isunsuitable due to humidity or quality, the COBRA energyrecovery unit is off and only the rooftop unit compressor runswhen cooling is required. Note that the COBRA energy recov-ery unit does not run and dampers are closed when the outdoorair is unsuitable for cooling and the mode is unoccupied. If out-door air is suitable, first stage cooling is COBRA energy recov-ery unit in economizer mode and all compressors are off.Second stage cooling adds the COBRA energy recovery unitcompressor and rooftop unit compressor no. 1.
In occupied mode, when the COBRA energy recovery unitcompressor runs in cooling mode, it is extracting heat from theincoming outdoor air and rejecting heat to the exhaust air. TheCOBRA energy recovery unit and rooftop unit fans run contin-uously. On a first stage call, all compressors will be off if theoutdoor air is suitable for free cooling. Otherwise, the COBRAenergy recovery unit compressor and rooftop unit compressorno. 1 will run whenever there is a first stage demand for cool-ing. On a second stage call, the COBRA energy recovery unitcompressor and rooftop unit compressor no. 1 and 2 will runwhenever there is a demand for cooling. If there is a demandfor humidity control but not cooling, only the COBRA energyrecovery unit compressor will run. If there is a field-installedCO2 sensor and the levels are below that sensor set point, thenthe unit will operate in the unoccupied mode sequence (i.e.,COBRA energy recovery unit dampers closed and rooftop unitoperation only to maintain space conditions).

Heating, units with COBRA™ energy recovery — The heat-ing changeover thermostat located on the COBRA energyrecovery unit hood determines the stage 1 to stage 2 switchoverpoint in heating mode.
In unoccupied mode, the COBRA energy recovery unit is offand all compressors are locked off. First stage heat is rooftopunit heat at 50%. Second stage heat is rooftop unit heat at100%.
In unoccupied mode, when the COBRA energy recovery unitcompressor runs in heat mode, it is extracting heat from theexhaust air and rejecting heat to the incoming outdoor air. So itis returning energy to the building that otherwise would be“thrown away”. The COBRA energy recovery unit and rooftopunit fans run continuously. The rooftop unit compressors arealways off. On a first stage call, the COBRA energy recoveryunit compressor is on in heat mode. Rooftop unit heat is off ifthe outdoor air is above the set point. Rooftop unit heat is on at50% if the outdoor air is below the set point. On a second stage
call, the COBRA energy recovery unit compressor is on in heatmode. Rooftop unit heat is on a 50% if the outdoor air is abovethe set point. Rooftop unit heat is on at 100% if the outdoor airis below the set point.Defrost — If the temperature of the 62AQ section condenser(exhaust air) coil drops below 28 F at the defrost thermostat(DFT) and the defrost timer is at the end of a timed period(adjustable to 30, 50, or 90 minutes), then the reversing valvesolenoid (RVS) is energized and the condenser fan contactor(s)are deenergized. This switches the position of the reversingvalve and shuts off the 62AQ section condenser (exhaust air)fan. The unit continues to defrost until the coil temperaturemeasured at the DFT reaches 65 F or the defrost cycle com-pletes a 10-minute cycle. At the end of the defrost cycle theRVS deenergizes and the exhaust fan motor energizes to put theunit in heating mode. If the space thermostat is satisfied duringa defrost cycle, then the 62AQ section will continue in theDefrost mode until the defrost cycle is complete.

Operating sequence, 50HJ015,017Cooling, units without economizer — When thermostat callsfor cooling, terminals G and Y1 are energized. The indoor(evaporator) fan contactor (IFC) and compressor contactor no.1 (C1) are energized, and evaporator-fan motor (IFM), com-pressor no. 1 and condenser fan(s) start. The condenser-fan mo-tor(s) runs continuously while unit is cooling. When the ther-mostat calls for a second stage of cooling by energizing Y2,compressor contactor no. 2 (C2) is energized and compressorno. 2 starts.Heating, units without economizer (if accessory or optionalheater is installed) — Upon a call for heating through terminalW1, IFC and heater contactor no. 1 (HC1) are energized. Onunits equipped for 2 stages of heat, when additional heat isneeded, HC2 is energized through W2.Cooling, units with EconoMi$er IV — When free cooling isnot available, the compressors will be controlled by the zonethermostat. When free cooling is available, the outdoor-airdamper is modulated by the EconoMi$er IV control to providea 50 to 55 F mixed-air temperature into the zone. As the mixed-air temperature fluctuates above 55 or below 50 F, the damperswill be modulated (open or close) to bring the mixed-air tem-perature back within control.
If mechanical cooling is utilized with free cooling, the out-door-air damper will maintain its current position at the timethe compressor is started. If the increase in cooling capacitycauses the mixed-air temperature to drop below 45 F, then theoutdoor-air damper position will be decreased to the minimumposition. If the mixed-air temperature continues to fall, the out-door-air damper will close. Control returns to normal once themixed-air temperature rises above 48 F.
If optional power exhaust is installed, as the outdoor-airdamper opens and closes, the power exhaust fans will be ener-gized and deenergized.
If field-installed accessory CO2 sensors are connected to theEconoMi$er IV control, a demand controlled ventilation strate-gy will begin to operate. As the CO2 level in the zone increasesabove the CO2 set point, the minimum position of the damperwill be increased proportionally. As the CO2 level decreasesbecause of the increase in fresh air, the outdoor-air damper willbe proportionally closed.
For EconoMi$er IV operation, there must be a thermostatcall for the fan (G). If the unit is occupied and the fan is on, thedamper will operate at minimum position. Otherwise, thedamper will be closed.
When the EconoMi$er IV control is in the occupied modeand a call for cooling exists (Y1 on the thermostat), the controlwill first check for indoor fan operation. If the fan is not on,then cooling will not be activated. If the fan is on, then the con-trol will open the EconoMi$er IV damper to the minimum po-sition.
On the initial power to the EconoMi$er IV control, it willtake the damper up to 21/2 minutes before it begins to positionitself. Any change in damper position will take up to 30 sec-onds to initiate. Damper movement from full closed to fullopen (or vice versa) will take between 11/2 and 21/2 minutes.
If free cooling can be used as determined from the appropri-ate changeover command (switch, dry bulb, enthalpy curve,differential dry bulb, or differential enthalpy), then the controlwill modulate the dampers open to maintain the mixed-air tem-perature set point at 50 to 55 F.
If there is a further demand for cooling (cooling second stage— Y2 is energized), then the control will bring on compressorstage 1 to maintain the mixed-air temperature set point. TheEconoMi$er IV damper will be open at maximum position.EconoMi$er IV operation is limited to a single compressor.Heating, units with EconoMi$er IVNOTE: The units have 2 stages of electric heat.

Condenser coil protectionPre-coated aluminum-fin coils have a durable epoxy-phenoliccoating applied to the fin prior to the fin stamping process toprovide protection in mildly corrosive coastal environments.Pre-coated coils have an inert barrier between the aluminum finand copper tube. This barrier electrically disconnects the dis-similar metals to minimize the potential for galvanic corrosion.This economical option provides substantial corrosion protec-tion beyond the standard uncoated coil construction.Copper-fin coils provide increased corrosion resistance inmoderate coastal environments where industrial air pollution isnot present. All copper coils eliminate bi-metallic constructionto eliminate the potential for galvanic corrosion. Application inindustrial environments is not recommended due to potentialattack from sulfur, sulfur oxide, nitrogen oxides, carbon andseveral other industrial airborne contaminants. In moderateseacoast environments, copper-fin coils have extended lifecompared to standard or pre-coated aluminum-fin coils.
E-Coated aluminum-fin coils undergo a precisely controlledscientific process that bonds an impermeable epoxy coating tothe specially prepared fin coil surface. E-Coating produces asmooth, consistent coating that is less brittle, more resilient andmore durable than previous postcoating processes. E-Coatedaluminum-fin coils offer economical protection and improvedcoil life in many contaminated environments.E-Coated copper-fin coils provide maximum protection invirtually all environments, this option combines the continu-ous, impenetrable barrier of the E-Coating process with the nat-ural resistance of an all-copper construction. E-Coated copper-fin coil assemblies ensure long life, even in environments thatcombine harsh coastal conditions with industrial contamina-tion.

EconoMi$er IVThe EconoMi$er IV factory-installed economizer packageincludes a gear-driven damper system that modulates the returnair and outdoor air supply to the rooftop unit in order to takeadvantage of “free cooling” with outdoor air when conditionsare suitable. The system utilizes industry proven technologyavailable for integrating the use of outdoor air for cooling withmechanical cooling for 3 through 25-ton rooftop units. Theintuitive EconoMi$er IV solid-state controller optimizes andenhances rooftop operation through reduced energy consump-tion, optimal zone comfort, and efficient equipment cycling.This is accomplished by operating the compressors when theoutdoor air temperature is too warm, integrating the compres-sors with outdoor air when free cooling is available, and lock-ing out the compressor when outdoor air temperature is toocold. The detailed sequence of operation is described in thecontrols section with a brief description of selected applicationitems here.Thermostat interface — The EconoMi$er IV control wasdesigned to work with conventional thermostats that have Y1(cooling stage 1), Y2 (cooling stage 2), W1 (heat stage 1), W2(heat stage 2), and G (fan). In addition, the EconoMi$er IV willsupport an occupied/unoccupied switch (typically integratedinto the thermostat or Thermidistat™ device). When the switchis closed, it provides a 24-vac signal to the unit for occupiedmode, and provides no signal to indicate unoccupied mode.The EconoMi$er IV control can be configured to allow differ-ent minimum economizer damper positions and to allow theuse of mechanical cooling in the occupied mode.Control features — The EconoMi$er IV controller providessuperior functionality for rooftop unit operation. EconoMi$erIV control features are included as follows:Remote minimum position control — The EconoMi$er IV con-troller can be used with a field-supplied and field-installedremote minimum position control switch that will enable anddisable the EconoMi$er IV to open or close the damper beyondthe minimum position for modified ventilation, providing 2 to10 vdc output.NOTE: Minimum position signal takes priority over the DCV(demand control ventilation) maximum position signal.Demand control ventilation (DCV) — The EconoMi$er IV hasDCV capability when using an IAQ sensor. This sensor is typi-cally installed in the return duct or occupied space. Whenimplementing a DCV control scheme with the EconoMi$er IV,the control algorithm will modulate the position of the damperbetween two user-configured damper positions, MaximumDCV position and Minimum Occupied position. Design air-flow rates for these two damper positions should be such thatwhen the damper is at the Maximum DCV position, enoughfresh ventilation air will be brought in to remove contaminantsand CO2 generated by sources other than people (i.e., since inunoccupied mode). The Maximum DCV position is intended tosatisfy the IAQ “Base Ventilation Rate.” The Minimum Occu-pied position design airflow rate should be sufficient to satisfy
ventilation requirements for removing CO2 from all sourcesincluding people at the maximum occupancy.IAQ sensors — EconoMi$er IV can be utilized with any IAQ(CO2) sensor that provides a 2 to 10 vdc output. The controllerwill modulate the outdoor air damper to provide ventilationbased on the sensor output and the IAQ setting of the controller.When used, an IAQ sensor will modulate the damper from theminimum position (base ventilation rate based on CO2 levels)to maximum position (full occupancy ventilation rate).Damper operation — The EconoMi$er IV allows the damper tobe configured for two adjustable damper positions includingmaximum position and occupied minimum position. The two(2) position damper capability is a unique feature ofEconoMi$er IV and includes operation flexibility as follows:
1. Minimum Occupied Position: This adjustable positionallows a minimum ventilation airflow rate through theunit during occupied periods (base ventilation rate).
2. Demand Control Ventilation (DCV) Maximum Position:A DCV maximum occupied position is provided whenusing an IAQ sensor for DCV. See Demand Control Ven-tilation section on this page and Control section forsequence, The DCV Maximum Position limits outdoorairflow into the rooftop when the DCV routine overridesthe mixed air sensor. Setting the DCV Maximum positionof the outdoor-air damper prevents large amounts of hotor cold air into the space.
Power exhaust — The EconoMi$er IV has the capability tocontrol one (1) stage of power exhaust for maintaining air bal-ance and pressurization. Control is activated based on outdoor-air damper position (adjustable) factory set at the “middle”position (damper halfway open).Compressor staging — The EconoMi$er IV is an integratedeconomizer and has the ability to utilize simultaneous outdoorair and compressors. The EconoMi$er IV can be configured tosupport economizer and compressor operation for up to 4 com-pressors. Only one or two compressor operation is availablewith 3 to 121/2 ton units.Changeover strategies — The EconoMi$er IV controller canbe configured to accommodate all available economizer controlstrategies that place the rooftop unit in economizer modeincluding: Switch — Used when a remote signal from an energy manage-ment system will enable and disable the EconoMi$er IV(remote enable control).Outdoor dry bulb — EconoMi$er IV will be enabled based onthe outside-air temperature. This is provided standard with theEconoMi$er IV.Differential dry bulb — EconoMi$er IV will be enabled when-ever the outside-air temperature is lower than the return airtemperature.
IMPORTANT: When the DCV Maximum position is setbelow the minimum position, the minimum position over-rides the maximum position, negating most DCV functions.

Outside air enthalpy — EconoMi$er IV will be enabled basedon the outside air enthalpy curves as shown in the EconoMi$erIV Changeover diagram below. The A, B, C, and D curvesshown have been in use for many years and have been includedas part of the latest ASHRAE 90.1 energy efficiency code. Thecurves are designed to take into consideration both outdoortemperature and humidity. These curves are used to set up theEconoMi$er IV controller to use the EconoMi$er IV for freecooling when the conditions to the left of the curve exist. Whenthe conditions are to the right of the curve, then outdoor aircooling will not be used and the outdoor air damper positionwill be set at the minimum position.
Deciding which curve is used is a function of the outdoor cli-mate and the type of economizer utilized. Since EconoMi$erIV is a fully integrated economizer, the range where outdoor aircan be utilized for free cooling is expanded and the A and Bcurves may be used. The control point table in the EconoMi$erIV Changeover diagram below provides assistance for whetherthe A and B curves will be suitable. In general terms, a hot and
humid climate may be a reason not to use the A curve, while acooler climate might be more applicable for using the A or Bcurve.
The EconoMi$er IV has expanded outdoor air capability. Fora changeover economizer which cannot utilize simultaneouseconomizer and compression, both A and B curves wouldpotentially be undesirable since the temperature and humiditylevels are too high without compression assistance to provideeffective cooling. Therefore, most changeover economizers uti-lize the D curve.Differential enthalpy — The EconoMi$er IV will be enabledbased on the comparison of the enthalpy of the return air andoutside air. When the outside air enthalpy is lower than thereturn side, the unit will be in economizer mode.
Using the EconoMi$er IV controller for implementing dif-ferent control changeover strategies requires the use of differ-ent combinations of dry bulb and humidity sensors as outlinedin the EconoMi$er IV Sensor Usage table.
