DIGITAL TEMPERATURE 

READOUT

By digitally monitoring the desired room temperature, the room is controlled more precisely than con-

ventional systems. The large, easy-to-read LED display can show either the set point or actual room 

temperature as selected by owner.

ONE-TOUCH 

OPERATION

When the unit is powered off, the unit can be returned directly to heating or cooling mode by pressing the 

‘Heat’ or ‘Cool’ buttons without the confusing power up sequence of some controls. One-touch control 

takes the guesswork out of unit control, delivering a more enjoyable experience and eliminating front-desk 

calls.

FAN SPEED MODE

Friedrich PTAC/PTHP units feature two fan speeds and AUTO mode for the user to select from. This 

allows the user to properly select the amount of airflow for the desired comfort level and also deliver quiet 

performance. 

CONSTANT FAN MODE

Pressing the Constant fan mode button will provide constant fan operation in cooling or heating modes. 

The fan speed selection is made by pressing either "High" or "Low" fan speed button.

INDIVIDUAL MODE 

& FAN CONTROL 

BUTTONS

By having separate control buttons and indicators for both fan and mode settings, the Friedrich digital 

control eliminates the confusion of previous digital PTACs. The accurate temperature setting provides 

greater guest comfort than other systems.

QUIET START/STOP

FAN DELAY

The fan start and stop delays prevent abrupt changes in room acoustics due to the compressor energiz-

ing or stopping immediately. Upon call for cooling or heating, the unit fan will run for five seconds prior to 

energizing the compressor. Also, the fan-off delay allows for “free cooling” by utilizing the already cool 

indoor coil to its maximum capacity by running for 30 seconds after the compressor. 

REMOTE THERMOSTAT 

OPERATION

Some applications require the use of a wall-mounted thermostat. All new Friedrich PTACs may be 

switched from unit control to remote thermostat control easily without the need to order a special model 

or accessory kit.

INTERNAL DIAGNOSTIC 

PROGRAM

The Friedrich digital PTAC features a self-diagnostic program that can alert maintenance to component 

failures or operating problems. The internal diagnostic program saves properties valuable time when 

diagnosing running problems.

SERVICE ERROR CODE 

STORAGE

All Friedrich PTAC units have self-diagnostic features that will store trouble codes in the case of an event.  

Storing the codes allows the property to see the trouble codes at a future time after the condition may 

have corrected.

ROOM FREEZE 

PROTECTION

When the PTAC senses that the indoor room temperature has fallen to 40

°

F, the unit will cycle on the 

fan (high) and the electric strip heat to raise the room temperature to 46

°

F, and then cycle off again. This 

feature works regardless of the mode selected and can be turned off. The control will also store the Room 

Freeze cycle in the service code memory for retrieval at a later date. This feature ensures that unoccupied 

rooms do not reach freezing levels where damage can occur to plumbing and fixtures.

RANDOM COMPRESSOR 

RESTART

Multiple compressors starting at once can often cause electrical overloads and premature unit failure. 

The random restart delay eliminates multiple units from starting at once following a power outage or initial 

power up. The compressor delay will range from 180 to 240 seconds.

CONDENSATE REMOVAL 

SYSTEM

Condenser fan utililzes slinger ring technology to pick up condensate from the base pan and disperse it 

on to the condenser coil where it evaporates. This helps to cool the coil and increase the energy efficiency 

of the unit.
