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 airflow is reduced or low outdoor
temperatures cause the indoor coil to freeze. When the indoor coil reaches 33°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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
High efciency rotary compressors are used on all Friedrich PTACs to maximize durability and ef-
ciency.
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 Friedrich PTAC return air filters feature an antimicrobial element that has proven to prevent mold and
bacterial growth in laboratory testing.PXFTB replacement
filter kits feature the same antimicrobial agent.
All filters 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 t
o 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
CONTROL DOOR
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.
