Friedrich Digital Control Features Continued
Heat pump models will automatically run the electric heater to quickly bring the room up to temperature when initially en-
Instant Heat
ergized, then return to heat pump mode. This ensures that the room is brought up to temperature quickly without the usual
Heat Pump Mode
delay associated with heat pump units.
The digital control monitors indoor conditions to ensure that the room temperature is within fi ve degrees of the setpoint. If
Even Heat
necessary 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.
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 is used to keep constant

airfl ow 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.
In the event of a compressor failure in heat pump mode the compressor may be locked out to provide heat through the
Emergency Heat
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 management system. Con-

trolling the unit from a remote location like the front desk can reduce energy usage and requires no additional accessories

The frost sensor protects the compressor from damage in the event that airfl ow is reduced or low outdoor temperatures
Indoor Coil Frost
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
The new Friedrich PD series units feature a indoor fan system design that reduces sound levels without lowering airfl ow
System and preventing proper air circulation.
The Friedrich PTAC benefi ts from quality components and extensive development to ensure a quiet, effi cient and depend-

able unit.
Friedrich's single-motor design allows for enhanced outdoor airfl ow and simplifi es the unit design without the need for

redundant components.
Rotary Compressor
High effi ciency rotary compressors are used on all Friedrich PTACs to maximize durability and effi ciency.
The Friedrich PTAC features a 24V AC terminal for connection to an auxiliary fan that may be used to transfer air to adjoin-
Auxiliary Fan Ready
ing rooms. Auxiliary fans can provide conditioning to multiple rooms without the requirement of multiple PTAC units.
Aluminum
All Friedrich PTACs are built with .04" endplates made from aluminum as opposed to steel. The endplates are typically the
Endplates most susceptible area for corrosion and aluminum is far more resistant to corrosion than even coated steel.
Diamnonblue
Diamonblue (seacoast protection) protects the outdoor coil from harsh environments. Comes standard on all PTAC units.
Technology
All Friedrich PTAC return air fi lters feature an anti-microbial element that has proven to prevent mold and bacterial growth
Top Mounted Anti-
in laboratory testing. PDXFT replacement fi lter kits feature the same anti-microbial agent. All fi lters are washable and reus-

able and are easily accessed from the top of the unit without the removal of the front cover.
Filtered Fresh Air
Friedrich PTAC units are capable of introducing up to 70 CFM of outside air into the conditioned space. The outdoor air
Intake passes through a mesh screen to prevent debris from entering the airstream.
