Friedrich Digital Control Features Continued

Instant Heat

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-

Heat Pump Mode

ated with heat pump units.

 

 

 

Even Heat Monitoring

The digital control monitors indoor conditions to ensure that the room temperature is within five 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

 

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 monitor-

Fan Cycle Control

ing and quiet start/stop fan delay only operate in fan cycle mode) Fan continuous mode is used to keep constant airflow 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 airflow 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 airflow and

preventing proper air circulation.

 

 

 

High Efficiency

The Friedrich PTAC benefits quality components and extensive development to ensure a quiet, efficient and dependable unit.

 

 

Single Motor

Friedrich’s single-motor design allows for enhanced outdoor airflow and simplifies the unit design without the need for redun-

dant components.

 

 

 

Rotary Compressor

High efficiency rotary compressors are used on all Friedrich PTACs to maximize durability and efficiency.

 

 

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 fins of

 

the coil.

 

 

Top Mounted Anti-

All Friedrich PTAC return air filters feature an anti-microbial element that has proven to prevent mold and bacterial growth in

laboratory testing. PDXFT replacement filter kits feature the same anti-microbial agent. All filters are washable and reusable

microbial Air Filters

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 filter to prevent debris from entering the airstream.
