Customize To Suit Your Needs
Select from a wide variety of features, factory-supplied options and accessories to build the ideal unit for your application and help reduce labor and installation costs.
Energy Efficient For Low Operating
Costs
Applied PTAC/PTHP units are AHRI certified units built with
quality components and exceed industry standards for energy
efficiency. This helps lower your utility costs by keeping
energy consumption down and may allow you to qualify for
electrical power company rebates.
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 coil
temperature is below 28°F, maximizing the amount of time
the unit operates in the more efficient heat pump mode.
Quiet Operation
The 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. troubleshooting the unit.

Easy To Use Digital Controls
Built-In Reliability and Durable
Construction
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.

Figure 3: Three-Level Sloped Basepan
Dehumidification:
The 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.
Positive condensate

Constant Room Temperature Monitoring
Units are designed to automatically sample the room temperature and adjust operation to meet desired temperature set
points.
Indoor Air Quality Options
▪ Damper control – Outdoor fresh air is brought in through
a manual or automatic (optional) damper.
▪ Fresh Air Damper – Can be added to your auto damper.
This will deliver 90 cfm of outdoor air into the space.
▪ Cleanable filters – Easy to remove, cleanable filters come
standard with each unit.
Figure 2: Manual Fresh Air Damper Control - Left End
Room Freeze Protection
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.
Electric Heat Override
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.
Compressor Protection
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 25°F
Memory Recall

Typical Installation Types
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 measure 165/8"
× 425/8". Louver frames should be used for panel wall and thin
wall applications to provide positive anchoring to the wall.
When an electrical subbase is used, the opening must start 3"
to 4" above the finished floor (including carpeting) to match
the height of the subbase selected. The subbase is available in
3" or 4" heights and has adjustable leveling legs that provide
up to an additional 1" height.
A 3" or 4" subbase is required for 265V models and is optional for 208/230V models

Remote Thermostat Control
The remote thermostat can be any thermostat that can
interface 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. EXCEPT in T'STAT mode,
the fan speed can be changed at the Touchpad and the fan
mode is dictated by the Remote t'stat. However, the control

Note: In terms of outputs, there are two types of
thermostats: relay contacts and solid state. If you
open the thermostat and don’t see relays then it
must be solid state. Manufacturers of solid state
output thermostats include loading resistors on their
installation kits. They are of 560 Ohm and 3W value.
These resistors are meant to load thermostat solid
state outputs in order for the output voltage to be
either 0 or 24VAC, i.e. no floating voltage. These
resistors are connected from W, Y, G to common (C),
respectively.
You can wire any type of 24Vac thermostat straight into
the REMOTE T’STAT connector of PTAC control boards,
667997102, 667997203 and 667997303 (Basic, Premium and
Auto-Changeover models) and the control boards will recognize the signals from them.

Drain Kits
External Drain
Drain kits are recommended for the heat pump units, and may
be used on any unit as required. They eliminate excessive
condensate accumulation which is generated during the heating cycle of the heat pump.
There are two types of drain kits employed with the Packaged
Terminal equipment; internal drains and external drains.
The external drain is attached to the rear of the wall sleeve,
over one of the weep holes. A cap is provided to seal the
remaining weep hole to force the excessive condensate to one
side.
The excess condensate is then evacuated from the wall sleeve
and allowed to drain to the outside of the building.
Internal Drain
An internal drain is mounted to the bottom of the wall sleeve
prior to installation of the sleeve. Position this drain on the
room side of the sleeve and connect to an internal collection
system.
When using a subbase, a 3" × 5" opening is provided in the
subbase for plumbing to the drain.

Architectural Louver
Airflow 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

The standby power connections, L1 STBY and L2 STBY are
meant to run the indoor motor at a separate voltage from the
other motors, compressor and outdoor motor. When used as
such, the jumpers, JH1 and JH2, must be cut. This renders L1
& L2 and L1 STBY and L2 STBY isolated from each other.
If there is no need to run the motors at a separate voltage the
L1 = L1 STBY and L2 = L2 STBY. Therefore one voltage is
used to run all motors.
If the jumpers are accidentally cut, then the connections can

Engineering Guide Specifications – PDAC/PDHP 16" x 42"
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.
Hydronic Heat - Heat Fan Lock Out – When the control is in the heat mode and calling for heat, the indoor fan shall not turn
on until the HFLO sensor is above 100°F. If at any time while the unit is in heat mode the HFLO sensor is below 90°F, the indoor
fan shall turn off immediately. Control will check if the HFLO sensor temperature is above 100°F for 2 seconds before resuming
indoor fan operation.
Hydronic with Intermediate Electric heat – 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
Reverse Cycle Heating Heat Pump with back-up electric heat – The reversing valve, the compressor, the outdoor air condenser fan motor and the indoor fan motor shall be energized. Reverse cycle heating shall occur when the outdoor coil temperature is
28°F and above. If outdoor coil temperature drops below 28°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 reverse cycle
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 28°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 run at its set speed.
Condensation accumulated during reverse cycle heating must NOT be evaporated against the indoor coil so as to prevent contamination of the indoor air with pollutants and odors. Condensation must be disposed of using a (external) (internal) drain system
as shown on plans.
Reverse Cycle Heating Heat Pump without back-up electric heat – 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 28°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 28°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 contamination of the indoor air with pollutants and odors. Condensation must be disposed of using a (external) (internal) drain system
as shown on plans.
