Product Features
The new Friedrich digital PTAC has state of the art features to improve guest comfort,indoor air quality and conserve energy.Through the use of specifically
designed control software for the PTAC industry Friedrich has accomplished what other.Manufacturer’s have only attempted –a quiet,dependable,affordable
and easy to use PTAC.
Below is a list of standard features on every Friedrich PTAC and their benifit to the owner.
DIGITAL TEMPERATURE
READOUT
By digitally monitoring the desired room temperature, the room is controlled more precisely than con-
ventional systems. The large, easy-to-read LED display can show either the set point or actual room
temperature as selected by owner.
INDIVIDUAL MODE
& FAN CONTROL
BUTTONS
By having separate control buttons and indicators for both fan and mode settings, the Friedrich digital
control eliminates the confusion of previous digital PTACs. The accurate temperature setting provides
greater guest comfort than other systems.
QUIET START/STOP
FAN DELAY
The fan start and stop delays prevent abrupt changes in room acoustics due to the compressor energiz-
ing or stopping immediately. Upon call for cooling or heating, the unit fan will run for ve seconds prior to
energizing the compressor. Also, the fan-off delay allows for “free cooling” by utilizing the already cool
indoor coil to its maximum capacity by running for 30 seconds after the compressor.
REMOTE THERMOSTAT
OPERATION
Some applications require the use of a wall-mounted thermostat. All new Friedrich PTACs may be
switched from unit control to remote thermostat control easily without the need to order a special model
or accessory kit.
INTERNAL DIAGNOSTIC
PROGRAM
The Friedrich digital PTAC features a self-diagnostic program that can alert maintenance to component
failures or operating problems. The internal diagnostic program saves properties valuable time when
diagnosing running problems.
Factory run-tested units reduce problems in the field.
ELECTRONIC
TEMPERATURE
LIMITING
By limiting the operating range, the property can save energy by eliminating “max cool” or “max heat” situ-
ations common with older uncontrolled systems. The new electronic control allows owners to set operat-
ing ranges for both heating and cooling independently of one another.
ROOM FREEZE
PROTECTION
When the PTAC senses that the indoor room temperature has fallen to 50°F, the unit will cycle on the fan
(high) and the electric strip heat to raise the room temperature to 55°F, and then cycle off again. This
feature works regardless of the mode selected and can be turned off.
RANDOM COMPRESSOR
RESTART
Multiple compressors starting at once can often cause electrical overloads and premature unit failure.
The random restart delay eliminates multiple units from starting at once following a power outage or initial
power up. The compressor delay will range from 120 to 240 seconds.
CONDENSATE REMOVAL
SYSTEM
Condenser fan utilizes slinger ring technology to pick up condensate from the base pan and disperse it on
to the condenser coil where it evaporates. This helps to cool the coil and increase the energy efciency
of the unit.
FACTORY RUN-TEST

11 PB
INTRODUCTION
Product Features
20
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 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

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.

Temperature Parameter
Indoor setting temperature (Ts)
Indoor ambient temperature (T1)
System Basic Function
Once the compressor starts, the compressor won’t stop with the change of the indoor temperature. Once the com
pressor stops, it can only start after a 3 mins delay. (The compressor can stop immediately at the time of mode swi
tchover, turning off the unit, adjusting setting temperature and turning off from a function error.)
1) Cooling Mode
Working conditions and process for cooling:
When T1≥Ts+2°F(1°C), the unit is running in cooling mode. Meanwhile, the compressor is running and the
fan is running at the setting fan speed;
When T1≤Ts-2°F(1°C), the compressor is OFF. Meanwhile, the fan will run at the setting fan speed for 15s
(CONSTANT FAN OFF); or run at the setting speed continuously (CONSTANT FAN ON);
When Ts-2 2°F(1°C)<T1<Ts+ 2°F(1°C), the unit keeps previous running status.
