DIGITAL DEFROST 

THERMOSTAT

The PZ-Series uses a digital thermostat to accurately monitor the outdoor coil conditions to allow the 

heat pump to run whenever conditions are correct. Running the PTAC in heat pump mode saves energy 

and reduces operating costs. The digital thermostat allows maximization of heat pump run time.

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.

SEPARATE HEAT/COOL 

FAN CYCLE  

CONTROL

The  owner  may  choose  between  fan  cycling  or  fan  continuous  mode  based  on  property  preference.    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.  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.

CENTRAL DESK 

CONTROL READY

All Friedrich digital PTACs have low voltage terminals ready to connect a central 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.

INDOOR COIL  

FROST SENSOR

The frost sensor protects the compressor from damage in the event that air

fl

ow is reduced or low outdoor 

temperatures  cause  the  indoor  coil  to  freeze.  When  the  indoor  coil  reaches  3

3

°F,  the  compressor  is 

disabled and the fan continues to operate based on demand. Once the coil temperature returns to 

59

°F, 

the compressor returns to operation.

ULTRAQUIET 

AIR SYSTEM

The PZ-Series units feature an indoor fan system design that reduces sound levels without lowering 

air

fl

ow or preventing proper air circulation.

HIGH EFFICIENCY

The Friedrich PTAC has been engineered so that all functional systems are optimized so that they work 

together to deliver the highest possible performance.

DUAL MOTOR 

The dual-motor design means that the indoor motor can run at slower speeds which reduces sound 

levels indoors.

ROTARY COMPRESSOR

ALUMINUM

 

ENDPLATES

Outdoor coil endplates made from 

 Aluminum

 reduce corrosion on the outdoor coil common with other coil 

designs.

TOP-MOUNTED  

ANTIMICROBIAL 

AIR FILTERS

All

 

fi

lters are washable, reusable and 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 

30

 CFM of outside air into the conditioned space. 

The outdoor air passes through a washable mesh screen to prevent debris from entering the airstream.

R-410A REFRIGERANT

Friedrich PTAC units use environmentally-friendly refrigerant.

BREAK-PROOF

GALVANIZED ZINC 

WALL SLEEVE AND 

BASE PAN

Galvanized  zinc  coated  steel  wall  sleeve  and  steel  base  pan  undergo  an  11-step  preparation 

process, are powder coated with a polyester finish and cured in an oven for exceptional durability.

DIAMONBLUE 

TECHNOLOGY

Diamonblue Technology protects the outdoor coil from harsh environments.

Break-proof control door design maintains the integrity of the unit.
