As one of the world’s largest heating, ventilation and air-conditioning manufacturers, McQuay stands behind its products with the strength of a global organization. And with local McQuay representation and manufactur-ing facility in Auburn, New York, we can provide you the hands-on support you need to make your building project a success.

McQuay Applied Packaged Terminal Air Condi-tioners and Heat Pumps (Applied PTAC/PTHP) are manufactured to institutional quality standards at our ISO 9002 certified manufacturing facility. Strict atten-tion to manufacturing details—from raw materials to the unit packaging—gives you a quality product, delivered on-time to support your construction schedule. Every unit is ETL Listed, MEA agency approved, ARI certified for performance and exceeds ASHRAE 90.1 efficiency requirements.

The high design standards and heavy-duty construc-tion of the McQuay Applied PTAC/PTHP can provide you with years of reliable service, quieter operation and low operating costs. In fact, many of our comfort condi-tioners have been operating for more than 30 years.

The Hydronic ExpertsMcQuay is a leading manufacturer of hydronic heat

equipment. We specialize in providing hydronic heat with a host of configurable options.

Modes • Cooling only mode with hydronic heat • Cooling only mode with hydronic heat and supplemental electric heat. • Top mounted hydronic coil (steam or hot water)

Controls-with built in hydronic logic • Normally open/normally closed valve control • Heat fan lockout – prevent the fan from coming on until there is heat in the pipes.

Customize to suit your needsSelect from a wide variety of features, factory-sup-

plied options and accessories to build the ideal system for your application and help reduce labor and installation costs. See "Accessories - Options" on page 18 to 24 for details on options and accessories.

Quiet OperationThe GentleFlo™ cross-tangential fan wheel design

of Applied PTAC/PTHP units provides whisper quiet operation while delivering maximum airflow required for proper air circulation. Separate indoor and outdoor fan motors further reduce operating sound levels and costs.

The heavy gauge construction of the chassis and cabinet minimizes vibration for quieter operation. Vibration isolators on the rotary compressor keep it running smoothly and quietly. The unit bulkhead is fully insulated to decrease outdoor sound transmission.

Energy efficient for low operating costsApplied PTAC/PTHP units are built with quality

components and exceed industry standards for energy efficiency for both new construction and replacement ap-plications. This helps lower your utility costs by keeping energy consumption down and may allow you to qualify for electrical power company rebates. Unit performance is ARI certified with an Energy Efficiency Ratio (EER) up to 12.1 EER and a heat pump Coefficient of Performance (COP) up to 3.6.

Built-in energy management logic comes standard with the unit’s digital controls. Features such as the Sleep Function allow users to decrease the set temperature at night and during unoccupied periods to conserve energy. For heat pump applications, electric heat comes on only when the outdoor temperature is below 35°F, maximizing the amount of time the unit operates in the more efficient heat pump mode.*Consult your utility provider for rebate opportunities.

Room ComfortEasy to use digital controls

The unit control pad offers digital readout and is easy to use when selecting fan speed, mode of operation and temperature setting. A precise digital temperature display provides guests with an exact comfort setting, thereby eliminating uncomfortable temperature swings and costly overheating/overcooling associated with non-digital electromechanical controls.

Standard digital touchpad control

DehumidificationThe cool/dry mode automatically controls humidity

by extending the cool cycle without sacrificing comfort for dehumidification. This mode comes standard with all units. The desired cooling mode (cool/dry for added dehumidification or regular cool) can be selected and locked by the owner or facility manager to meet comfort and dehumidification requirements.

Constant room temperature monitoringUnits are designed to automatically sample the room

temperature and adjust operation to meet desired tem-perature set points.

Built-in Reliability & Durable ConstructionHigh-grade cabinetry

Applied PTAC/PTHP cabinets are constructed of 18-gauge steel with baked on powder coat paint for maximum durability and aesthetic appeal. Grilles have two-way adjustment allowing air to be directed where it is needed.

Positive condensate removalOur unique three level sloped basepan design pro-

vides positive condensate removal to prevent condensate build-up or overflow.

• Condenser Coil – Protected with E-Coating, made up of an epoxy primer and acrylic top coat that is electrostatically applied and baked on. Also, there is a dielectric strip located between the condenser and base pan.

• Condenser Fan Blade and Slinger Ring – Constructed of Noryl® PPO which is a strong engi-neering plastic that has excellent flame resistance and dimensional stability over a wide range of service temperatures. Noryl has low moisture absorption, excellent strength and stiffness.

• Condenser Fan Motor – Specially coated by the manufacturer with zinc end plates.

• Compressor – Protective coating applied by the manufacturer on the exterior to enhance equipment life and performance.

• Outdoor Louver – Made of aluminum, etched and anodized for maximum corrosion protection. Avail-able in stamped or architectural styles.

Easy Installation and Service DesignQuick link connections

Applied PTAC/PTHP units are designed for easy access with quick link connections to the control box. The simple slide in/slide out configuration makes it easy to access the electric heater, indoor and outdoor fans, motors, and compressor.

Easy fan removal

Easy to read LED diagnosticsSensors in the unit continually monitor the indoor

coil, outdoor coil, and outdoor air conditions. If abnormal conditions are detected, an error code is displayed, removing the guess work in troubleshooting a unit.

Easy fan motor removal

Room freeze protectionWhen the unit senses temperatures of 40°F or lower

in an unoccupied room, the heat mode is automatically initiated to prevent freezing. The outdoor fan and com-pressor are stopped to help prevent coil freeze.

Electric heat overrideHeat pump units can be manually switched to electric

heat, providing added freeze protection if the heat pump mode is not available due to a compressor failure.

Compressor protectionThe life of the compressor is extended through built

in protection logic such as: • High temperature protection if the

compressor temperature exceeds 154°F • Minimum run time • Minimum off time • Random restart after a power outage • Low ambient lockout when the outdoor air

temperature falls below 35°F

Memory recallControl settings are saved in a non-volatile memory,

allowing the last settings to be recalled after a loss of power.

Seacoast construction Application of air conditioning equipment in a cor-

rosive environment requires special consideration. The corrosive nature of salt water vapor, chlorine and acid vapor, demands a unit that can withstand these environ-ments. Any metal portion that is exposed to a corrosive vapor must be specially treated.

There is no coating or treatment that will allow a unit to last indefinitely, however, the Applied PTAC is avail-able with parts that receive special corrosion protection that can help dramatically extend the life of the unit.

• Wall Sleeve – The entire Custom Wall Sleeve (CWS) or cabinet/wall sleeve is constructed of G-60 galvanized, phosphatized, 18-gauge steel. Treated inside and outside with a baked-on epoxy based powder coat paint to protect it from the corrosive effects of salt spray. The Basic Wall Sleeve (BWS) is constructed of galvanized, primed and pre-painted antique ivory 18-gauge steel.

• Base Pan – Protected with Casing Guard coating, providing a comprehensive corrosion protection for all exposure conditions.

Wall Construction ExamplesHow to Select The Correct Wall CabinetThe minimum cabinet depth is 10.75". This is required

because the wall sleeve MUST extend a minimum of 1.625" into the room and 9.125" is required to cover the chassis. This totals 10.75".

Standard cabinets range from 10.75" to 18.75" in 1" increments. For other requirements, consult the factory.

If the wall sleeve extends into the room more than 1.625", add the inside measurement to the 9.125" required to cover the chassis. This will be the depth of the wall cabinet.For example:

The wall sleeve extends 3.25" into room + 9.125" = 12.75" deep cabinet or if the wall sleeve extends 9.25" into room + 9.125" = 18.75" deep cabinet would be the closest fit.

Wall Opening Requirements – 16" × 42"When roughing in the opening for the wall sleeve,

sufficient clearance from the walls and floor is required. The wall sleeve should be positioned a minimum of 5/8" from the finished side wall to accommodate the room cabinet. A minimum distance of 3" above the finished floor is required for return air.

The rough opening should measure 161/4" high × 421/4" wide. When using a louver frame, the opening must mea-sure 165/8" × 425/8". Louver frames should be used for panel wall and thin wall applications to provide positive anchoring to the wall.

Electrical ServiceAll wiring should be in accordance with all local and

National Electrical Code requirements.Units are supplied with an attachment cord and plug

which exit from the bottom of the conditioner on the control side. The cord for 115V, 208V and 230V has a usable length of 72" (1829mm) from where it exits the conditioner. The use of extension cords to increase the length of the plug/cord set is not recommended. Units to operate on 265V are supplied with a 18" (457mm) cord for connection to a subbase.

The attachment plug size should be used to determine the circuit ampacity and overcurrent protection. Time delay, overcurrent protection devices are recommended to prevent unit damage and to avoid nuisance tripping.

Receptacles are generally located beneath the condi-tioner, on or recessed in the wall so it is concealed by the conditioner overhang and kickplate (see page 17).

Wall Mounted Thermostats – Quick Selection Guide

Accessories–Options


Remote Wall Mounted Thermostats Remote Thermostat Control

The Remote Thermostat can be any thermostat that can interface with an electronic thermostat via RCBWYG terminals. The Control Selection jumper must be in T’STAT position. During a call the remote thermostat will pass R back to the controller on a respective terminal. The push buttons on the touchpad become inactive in the remote thermostat mode. However, the control pad LED display will indicate the mode of operation, and the room tem-perature.

Remote Mounted Thermostat InstallationConsiderations when units are furnished with remote

mounted thermostats:1. When wiring the low voltage plug and receptacle

disconnect, provide enough wire to move harness out of the way for chassis removal.

2. If secondary units are to be employed, see connections in wiring illustration below. The number of secondary units that can be connected is limited to 32 units.

3. When using a programmable wall thermostat, connect it to the terminal board remote thermostat plug. Refer to the instructions furnished with the chosen thermostat.

IMPORTANTAir flow required for PTAC units must not be restricted by exterior plants or walls. Plants or shrubs must not be planted in close proximity to the outside grille of the PTAC unit. Vegetation planted too close to grilles will cause discharge air to be recirculated, thereby increasing electrical consumption. Warranty will be voided if it is determined that the compressor life is shortened from overheating due to close proximity of outside obstructions.

Note: Discharge air restrictions include, but are not limited to:

• Vegetation• Concrete walls or barriers• Overhangs that do not allow discharge air to rise• Installation of bug screen of any kind



Energy Saving OptionsAutomatic Change over, Remote Mounted Thermostat

Thermostats can be obtained to switch from heating to cooling and from cooling to heating automatically. With automatic change over, the operation of the heating cycle or the cooling cycle is determined by the temperature re-quirement of the space. Most thermostats with this feature are set to change over when the room temperature varies 3-1/2oF from the set-point. The unit is placed in the cooling mode when the set-point is over 3-1/2oF; 3-1/2oF under the set point places the unit in the heating mode. This 3-1/2oF variation is usually adjustable from a 1/2oF dead band to a 5oF dead band. Each cycle is run until the set point tem-perature is reached, then that cycle is de-energized. On some thermostats, the automatic change over function can be overridden manually by moving the thermostat selector switch to “heat” or to “cool.”

The fan operation, with an automatic change over thermostat, is controlled by the fan selector switch. When placed in the “fan” mode, the fan runs continuously. When placed in the “auto” mode, the fan will only energize when the thermostat calls for heating or cooling.

• Program Setback Control With the Programmable Touchpad, four (4) different

periods, Morn., Day, Eve., or Nite, can be indepen-dently programmed for start time, Heat setting and Cool setting. There are additional energy savings with Programmed Setback Control.

• Fresh Air Dampers McQuay Packaged Terminal conditioners can be

furnished with an automatic fresh air damper in lieu of a manual fresh air damper. The automatic damper is wired in parallel to the indoor fan relay.

In the Set-up menu on the touchpad, with the damper set to “AU” (Automatic) and the OAS (Outdoor Air Sensor) is > (greater than) 40º F but is < (less than) 90º F and the IAS (Indoor Air Sensor) is > (greater than) 50º F and if the unit is placed in the cycle mode, the fan and damper cycle as the thermostat cycles. If the unit is placed in the “constant” mode, the fan runs continuously and the damper is always open subject to the sensors.

The automatic damper feature can be overridden in the Set-up menu by placing the automatic damper setting in the “CL” (Closed) position. In this posi-tion, the damper remains closed during all cycles of the unit.

• Special Paint The Standard paint on the NYC Style unit is Antique

Ivory with a contrasting Oxford Brown subbase. This color combination blends well with the most interior color schemes. A durable electrostatically applied, baked on, antique ivory urethane powder paint is used that resists smudges and corrosion. Each steel component is painted separately and oven baked for durability.

Heating/Coolingchassis–Chassis shall be slide-in, plug-in type with a self-contained, hermetically sealed refrigerant circuit. All chassis sheet metal parts shall be constructed of either powder-coated A-60 or G-60 galvanized steel for maximum corrosion resistance. The chassis shall consist of the following components:Vibration isolated compressor; rifled copper tubed evaporator and condenser coils with high efficiency raised lance aluminum plate fins mechanically expanded to the tubes for maximum heat transfer; and a capillary restrictor type refrigerant metering device. Coils shall be factory tested at 300 psig. (Heat pump models shall also include reversing valve and charge balancing device). A positive closing (manual) fresh air damper may be located within the chassis to provide fresh air during fan operation.Airflow system shall include separate fan motors for the condenser and evaporator sections. The condenser fan motor shall be a single-speed, totally enclosed, permanently lubricated fan motor. Condenser fan shall be propeller-type with a slinger ring and shall be constructed of aluminum. The indoor fan motor shall be a two-speed, totally enclosed; permanently lubricated fan motor must be positioned on the indoor side of the bulkhead so as to be completely within the conditioned, filtered airstream. The indoor blower fan shall be a forward-curved tangential design to provide even airflow across the evaporator coil.

During the cooling cycle:The compressor, the outdoor fan motor and the indoor fan motor shall be energized. Condensation accumulated on the evaporator coil shall be drained into the outdoor section where it is to be picked up by the condenser fan/slinger ring and evaporated against the outdoor coil. In the cool mode, the compressor will cut in if the space temperature is at least 1°F above the thermostat set point and will cut out when the space temperature is approximately 2°F below set point, subject to timing protections.

During the heating cycle:ElectricResistanceHeat–Control will call for electric heat when the space temperature is 1°F lower that the set point. The control will cease its call when the space temperature is 3°F or higher than set point.Only the indoor fan motor and electric resistance heater are energized. The outdoor condenser fan motor and compressor shall not be energized. Heater shall be open wire type with quick response and high limit cutout. Heaters shall be sized to meet heating require-ments as shown on the schedule. Electric resistance heaters must be placed behind the indoor evaporator coil and must not be visible through the indoor discharge grille. When the heater cuts out the indoor fan continues to run for 15 seconds at the set speed, regard-less of On or Off mode. After 15 seconds the fan will stop running if unit is in Off mode, else the fan operation will depend on Fan Continuous or Fan Cycle setting.Hydronic, Hot water or Steam, heat – Only the indoor fan motor, the (normally open) (normally closed) valve and automatic fresh air damper shall be energized. The outdoor condenser fan motor and compressor shall not be energized.

HydronicHeatWhen the control is in the heat mode and calling for heat, the indoor fan shall not turn on until the HFLO sensor is above 115°F. If at any time while the unit is in heat mode the HFLO sensor is below 95°F, the indoor fan shall turn off immediately. Control will check if the HFLO sensor temperature is above 115°F for 2 seconds before resuming indoor fan operation.

HydronicwithIntermediateElectricheat–Upon the call for heating and thereafter the HFLO sensor temperature will be monitored. A trend in HFLO sensor Temperature shall determine which form of heat is to be used. If during the 90 seconds that Hydronic is the heat source and the HFLO sensor is above 105°F and is increasing at 2°F per minute then Hydronic is the heat source. If during this 90 seconds, the temperature of the HFLO sensor is above 105°F and is not increasing at 2°F per minute then Electric is the heat source. The hydronic valve is opened for 90 seconds. After 90 seconds whether Hydronic or Electric provides the heating is determined by the following:

If HFLO sensor temperature is less that 105°F, Electric provides the heat.If HFLO sensor temperature is greater than 115°F, Hydronic provides the heat


ReverseCycleHeatPumpwithback-upelectricheat–The reversing valve, the compressor, the outdoor condenser fan motor and the indoor fan motor shall be energized. Reverse cycle heating shall occur when the outdoor temperatures are 35°F and above. If outdoor coil temperature drops below 20°F or the Outdoor air temperature drops to 35°F or less, Electric heat is the only source of heat. When the Outdoor coil temperature raises back to 40°F and above, then the Compressor or Electric heater is used.A temperature-sensing device shall be used to monitor the outdoor coil temperature to limit frost buildup. Defrosting of the outdoor coil will be activated when outdoor coil temperature drops below 20°F or outdoor air temperature drops to 35°F or less. Defrosting is terminated when outdoor coil temperature rises back to 40°F. During defrosting, both compressor and the outdoor fan are turned off. The indoor fan will run at its set speed. Condensation accumulated during reverse cycle heating must NOT be evaporated against the indoor coil so as to prevent contami-nation of the indoor air with pollutants and odors. Condensation must be disposed of using a (external) (internal) drain system as shown on plans.

ReverseCycleHeatPumpwithoutback-upelectricheat–The reversing valve, the compressor, the outdoor condenser fan motor and the indoor fan motor shall be energized. Reverse cycle heating shall occur when the outdoor temperatures are 35°F and above. If outdoor coil temperature drops below 20°F or the Outdoor air temperature drops to 35°F or less, the compressor stops and there is no source of heat. When the Outdoor coil temperature raises back to 40°F and above, then the compressor reverse cycle is the heat source.A temperature-sensing device shall be used to monitor the outdoor coil temperature to limit frost buildup. Defrosting of the outdoor coil will be activated when outdoor coil temperature drops below 20°F of outdoor air temperature drops to 35°F or less. Defrosting is terminated when outdoor coil temperature rises back to 40°F. During defrosting, both compressor and the outdoor fan are turned off. The indoor fan will stop if indoor coil temperature falls below 78°F. It will restart at its set speed when indoor coil temperature rises back to 80°F. Condensation accumulated during reverse cycle heating must NOT be evaporated against the indoor coil so as to prevent contami-nation of the indoor air with pollutants and odors. Condensation must be disposed of using a (external) (internal) drain system as shown on plans.

Electricheatoverride– Heat pump units can be manually switched to electric heat, providing added freeze protection if the heat pump mode is not available due to a compressor failure.

Controlmodule–The PDAN Control module is used to control a PDAN unit that includes both an integral air conditioner and a source of heat. The Digital Control is operated with a Touchpad, IR Remote or 24 volt, Wall Mounted Thermostat.

Roomfreezeprotection– When the unit senses temperatures of 40°F or lower in an unoccupied room, the heat mode is automatically initiated to prevent freezing. The outdoor fan and compressor are stopped to help prevent coil freeze.

Compressorprotection– The life of the compressor is extended through built in protection logic such as: • High temperature protection if the compressor temperature exceeds 154°F • Minimum run time • Minimum off time • Random restart after a power outage • Low ambient lockout when the outdoor air temperature falls below 35°F
