Room temperature is digitally monitored, providing for more precise control than conventional systems.
The large, easy-to-read LED display can show either set-point or actual room temperature as selected
by owner.
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 guesswork out of unit control, delivering a more enjoyable experience and eliminating front-desk
calls.
All 2008 “D” model and later PTAC units can be controlled by a wireless hand held remote control. The
remote control places all of the controls of the PTAC unit conveniently in the palm of your guest’s hands.
The remote can operate from distances up to 25 feet away. The remote is sold seperately as accessory
PDXRC.
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.
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 ve 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.
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.

The new Friedrich digital PTAC features a self diagnostic program that can alert maintenance to compo-
nent failures or operating problems. The internal diagnostic program saves properties valuable time when
diagnosing running problems.
The self diagnosis program will also store error codes in memory if certain conditions occur and correct
themselves such as extreme high or low operating conditions or activation of the room freeze protection
feature. Storing error codes can help properties determine if the unit faced obscure conditions or if an
error occurred and corrected itself.
The on-board processor monitors time between demand cycles (heat or cool) and will cycle the fan every
9 minutes to sample the room condition and determine if the desired conditions are met. This allows the
room to have similar benets to a remote mounted thermostat without the complication or cost of a wall-
mounted thermostat.
By limiting the operating range, the prop er ty can save energy by eliminating “max cool” or “max heat” situ ations common with older uncontrolled systems. The new electronic control allows owners to set operating ranges for both heating and cooling independently of one another.
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
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 xtures.

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.

Diamonblue corrosion protection comes standard on all models. Diamonblue protects the outdoor coil
against deterioration, and extends the life of the unit.
The new Friedrich PTAC uses a digital thermostat to accurately monitor the outdoor coil conditions to al-
low 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.
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.
The digital control monitors indoor conditions to ensure that the room temperature is within ve degrees
of the setpoint. If necessary, the unit will cycle the electric heat to maintain the temperature. This feature
ensures guest comfort by delivering the heating benets of an electric heater while maintaining the ef-
ciency benets of a heat pump.
The owner 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 constantly circulates the air while the unit is ‘ON’. Fan cycle will conserve energy by only
operating the fan while the compressor or electric heater is operating.
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.
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.
The frost sensor protects the compressor from damage in the event that airow 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.

Friedrich PD series units feature an indoor fan system design that reduces sound levels without lowering
airow or preventing proper air circulation.
The Friedrich PTAC has been engineered so that all functional systems are optimized so that they work
together to deliver the highest possible performance.
Friedrich’s single-motor design allows for enhanced outdoor airow and simplies the unit design without the need for redundant components.
High efciency rotary compressors are used on all Friedrich PTACs to maximize durability and ef-
ci ency.
The Friedrich PTAC features a 24V AC terminal for connection to an auxiliary fan that may be used to
transfer air to adjoining rooms. Auxiliar y fans can provide conditioning to multiple rooms without the
need for multiple PTAC units.
All Friedrich PTACs are built with .04" endplates made from aluminum as opposed to steel. The end-
plates are typically the most susceptible area for corrosion and aluminum is far more resistant to corro-
sion than even-coated steel.
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.
Friedrich PTAC units are capable of introducing up to 70 CFM of outside air into the conditioned space.
The outdoor air passes through a washable mesh lter to prevent debris from entering the airstream.
Friedrich PTAC units use environmentally-friendly refrigerant.
This adv anced corro sion protec tion treatm ent protec ts the
outdoo r coil against d eteriora tion and exte nds the life of
the unit e specially in h arsh coasta l environmen ts.
