ELECTRONIC
TEMPERATURE
LIMITING
By limiting the operating range, the property can save energy by eliminating “max cool” or “max heat”
situations common with older uncontrolled systems. The new electronic control allows owners to set
operating ranges for both heating and cooling independently of one another.
DIAMONBLUE™
TECHNOLOGY
Diamonblue anticorrosive coating protects the outdoor coil from harsh environments. Standard on all
models.
DIGITAL DEFROST
THERMOSTAT
The PD Series uses a digital thermostat to accurately monitor the outdoor coil conditions to allow the
heat pump to run whenever conditions are correct. Running the PTAC in heat pump mode saves energy
and reduces operating costs. The digital thermostat allows maximization of heat pump run time.
INSTANT HEAT
HEAT PUMP MODE
Heat pump models will automatically run the electric heater to quickly bring the room up to temperature
when initially energized, then return to heat pump mode. This ensures that the room is brought up to
temperature quickly without the usual delay associated with heat pump units.
EVEN HEAT MONITORING
The digital control monitors indoor conditions, ensuring room temperature is within 5° F of the setpoint. If
needed, the unit will briey cycle the electric heater to maintain temperature. This feature preserves the
efciency benets of a heat pump while ensuring guest comfort.
SEPARATE HEAT/COOL
FAN CYCLE
CONTROL
Using the "Constant Fan" one may choose between fan cycling or fan continuous mode based on property
preference. (Note: Even heat monitoring and quiet start/stop fan delay only operate in fan cycle mode) Fan
continuous mode is used to keep constant airflow circulation in the room during all times the unit is ‘ON’. Fan
cycle will conserve energy by only operating the fan while the compressor or electric heater is operating. The
ability to set the fan cycling condition independently between heating and cooling mode will increase
user comfort by allowing the choice of only constantly circulating air in the summer or winter time (unlike
other PTAC brands that only allow one selection).
EMERGENCY
HEAT OVERRIDE
In the event of a compressor failure in heat pump mode, the compressor may be locked out to provide
heat through the resistance heater. This feature ensures that even in the unlikely event of a compressor
failure, the room temperature can be maintained until the compressor can be serviced.
DESK CONTROL
READY
All Friedrich digital PTACs have low voltage terminals ready to connect a desk control energy manage-
ment system. Controlling the unit from a remote location like the front desk can reduce energy usage and
requires no additional accessories on the PTAC unit.
INDOOR COIL
FROST SENSOR
The frost sensor protects the compressor from damage in the event that airow is reduced or low outdoor
temperatures cause the indoor coil to freeze. When the indoor coil reaches 30°F, the compressor is
disabled and the fan continues to operate based on demand. Once the coil temperature returns to 45°F,
the compressor returns to operation.
ULTRAQUIET
AIR SYSTEM
The PD- series units feature an indoor fan system design that reduces sound levels without lowering
airow or preventing proper air circulation.
HIGH EFFICIENCY
The Friedrich PTAC has been engineered so that all functional systems are optimized so that they work
together to deliver the highest possible performance.
DUAL MOTOR
The dual-motor design means that the indoor motor can run at slower speeds which reduces sound
levels indoors.
ROTARY COMPRESSOR
High efciency rotary compressors are used on all Friedrich PTACs to maximize durability and ef-
ciency.
STAINLESS STEEL
ENDPLATES
Outdoor coil endplates made from stainless steel reduce corrosion on the outdoor coil common with other
coil designs.
TOP-MOUNTED
ANTIMICROBIAL
AIR FILTERS
All Friedrich PTAC return air lters feature an antimicrobial element that has proven to prevent mold and
bacterial growth in laboratory testing. PDXFT replacement lter kits feature the same antimicrobial agent.
All lters are washable, reusable and easily accessed from the top of the unit without the removal of the
front cover.
FILTERED FRESH
AIR INTAKE
Friedrich PTAC units are capable of introducing up to 75 CFM of outside air into the conditioned space.
The outdoor air passes through a washable mesh screen to prevent debris from entering the airstream.
R-410A REFRIGERANT
Friedrich PTAC units use environmentally-friendly refrigerant.
