Friedrich Digital Control Features Continued
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 associ-
ated with heat pump units.
Even Heat Monitoring
The digital control monitors indoor conditions to ensure that the room temperature is within fi ve degrees of the setpoint. If neces-
sary the unit will cycle the electric heat to maintain the temperature. This feature ensures guest comfort by delivering the heating
benefi ts of an electric heater while maintaining the effi ciency benefi ts of a heat pump.
Fan Cycle Control
The owner may choose between fan cycling or fan continuous mode based on property preference. (Note: Even heat monitor-
ing and quiet start/stop fan delay only operate in fan cycle mode) Fan continuous mode is used to keep constant airfl ow circula-
tion 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.
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 resis-
tance heater. This feature ensures that even in the unlikely event of a compressor failure the room temperature can be main-
tained until the compressor can be serviced.
Desk Control Ready
All Friedrich digital PTACs have low voltage terminals ready to connect a desk control energy management system. Control-
ling the unit from a remote location like the front desk can reduce energy usage and requires no additional accessories at the
PTAC.
Indoor Coil Frost Sensor
The frost sensor protects the compressor from damage in the event that airfl ow is reduced or low outdoor temperatures cause
the indoor coil to freeze. When the indoor coil reaches 30°F the compressor is diabled and the fan continues to operate based
on demand. Once the coil temperature returns to 45°F the compressor returns to operation.
Ultra-Quiet Air System
The new Friedrich PD series units feature a indoor fan system design that reduces sound levels without lowering airfl ow and
preventing proper air circulation.
High Effi ciency
The Friedrich PTAC benefi ts quality components and extensive development to ensure a quiet, effi cient and dependable unit.
Single Motor
Friedrich’s single-motor design allows for enhanced outdoor airfl ow and simplifi es the unit design without the need for redun-
dant components.
Rotary Compressor
High effi ciency rotary compressors are used on all Friedrich PTACs to maximize durability and effi ciency.
Auxiliary Fan Ready
The Friedrich PTAC features a 24V AC terminal for connection to an auxiliary fan that may be used to transfer air to adjoining
rooms. Auxiliary fans can provide conditioning to multiple rooms without the requirement of multiple PTAC units.
Aluminum Endplates
All Friedrich PTACs are built with .04" endplates made from aluminum as opposed to steel. The endplates are typically the most
susceptible area for corrosion and aluminum is far more resistant to corrosion than even coated steel.
Seacoast Protection
Optional Seacoast protection is available to protect the outdoor coil from harsh environments. The Friedrich Seacoast process
includes dipping the entire outdoor coil in a 7-step coating process that provides superior protection to only coating the fi ns of
the coil.
Top Mounted Anti-
microbial Air Filters
All Friedrich PTAC return air fi lters feature an anti-microbial element that has proven to prevent mold and bacterial growth in
laboratory testing. PDXFT replacement fi lter kits feature the same anti-microbial agent. All fi lters are washable and reusable
and are 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 70 CFM of outside air into the conditioned space. The outdoor air passes
through a washable mesh fi lter to prevent debris from entering the airstream.
