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 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 efciency benets of a heat pump.
Separate Heat/Cool
Fan Cycle Control
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
airow 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 management system.
Controlling 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 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.
Ultra-Quiet Air
System
The new Friedrich PD series units feature an indoor fan system design that reduces sound levels without lowering airow
and preventing proper air circulation.
High Efciency
The Friedrich PTAC benets from quality components and extensive development to ensure a quiet, efcient and
dependable unit.
Dual Motor
Friedrich's new dual motor design allows for the quietest and most efcient units yet.
Rotary Compressor
High efciency rotary compressors are used on all Friedrich PTACs to maximize durability and efciency.
Stainless Steel Endplates
Outdoor coil endplates made from stainless steel reduce corrosion on the outdoor coil common with other coil designs.
Diamonblue
Technology
Diamonblue (seacoast protection) protects the outdoor coil from harsh environments. Comes standard on all
PTAC units.
Top Mounted
Antimicrobial
Air Filters
All Friedrich PTAC return air lters feature an anti-microbial element that has proven to prevent mold and bacterial
growth in laboratory testing. PDXRTA replacement lter kits feature the same anti-microbial agent. All lter 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 75 CFM of outside air into the conditioned space. The
outdoor air passes through a mesh screen to prevent debris from entering the air stream.
