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 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 benets of an electric heater while maintaining the

efciency bene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 monitoring and quiet start/stop fan delay only operate in fan cycle mode). Fan continuous

mode is used to keep constant air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.

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 air 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 airow and preventing proper air circulation.

High Efciency

The Friedrich PTAC benets quality components and extensive development to ensure a quiet, efcient

and dependable unit.

Single Motor

Friedrich’s single-motor design allows for enhanced outdoor airow and simplies the unit design without

the need for redundant components.

Rotary Compressor

High efciency rotary compressors are used on all Friedrich PTACs to maximize durability and

ef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 ns of the coil.

Top Mounted Anti-

microbial 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. PDXFT replacement lter kits feature the same anti-microbial

agent. All 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  lter to prevent debris from entering the airstream.
