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 five 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 benefits of an electric heater while maintaining the efficiency benefits 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
airflow 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.
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 management 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 airflow 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.
The new Friedrich PD series units feature an indoor fan system design that reduces sound levels without lowering airflow
and preventing proper air circulation.
The Friedrich PTAC benefits from quality components and extensive development to ensure a quiet, efficient and
dependable unit.
Friedrich's new dual motor design allows for the quietest and most efficient units yet.
High efficiency rotary compressors are used on all Friedrich PTACs to maximize durability and efficiency.
Outdoor coil endplates made from stainless steel reduce corrosion on the outdoor coil common with other coil designs.
Diamonblue (seacoast protection) protects the outdoor coil from harsh environments. Comes standard on all
PTAC units.
All filter are washable and reusable and are easily accessed from the top of the unit without the removal
of the front cover.
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.
