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 briefly cycle the electric heater to maintain temperature. This feature preserves the 

efficiency benefits 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 airflow 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 

airflow 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  efficiency  rotary  compressors  are  used  on  all  Friedrich  PTACs  to  maximize  durability  and  effi-

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 filters feature an antimicrobial element that has proven to prevent mold and 

bacterial growth in laboratory testing. PDXFT replacement filter kits feature the same antimicrobial agent. 

All filters 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.
