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.

ONE-TOUCH

OPERATION

When the unit is powered off, the unit can be returned directly to heating or cooling mode by pressing the

‘Heat’ or ‘Cool’ buttons without the confusing power up sequence of some controls. One-touch control

takes the guesswork out of unit control, delivering a more enjoyable experience and eliminating front-desk

calls.

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.

SERVICE ERROR CODE

STORAGE

All Friedrich PTAC units have self-diagnostic features that will store trouble codes in the case of an event.

Storing the codes allows the property to see the trouble codes at a future time after the condition may

have corrected.

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 40

F, the unit will cycle on the

fan (high) and the electric strip heat to raise the room temperature to 46

F, and then cycle off again. This

feature works regardless of the mode selected and can be turned off. The control will also store the Room

Freeze cycle in the service code memory for retrieval at a later date. This feature ensures that unoccupied

rooms do not reach freezing levels where damage can occur to plumbing and xtures.

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 180 to 240 seconds.

CONDENSATE REMOVAL

SYSTEM

Condenser fan utilizes slinger ring technology to pick up condens

ate 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.

Product Features

DIAMONBLUE™

TECHNOLOGY

Diamonblue anticorrosive coating protects the outdoor coil from harsh environments. Standard on all

models.

DIGITAL DEFROST

THERMOSTAT

The PD 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.

EVEN HEAT MONITORING

The digital control monitors indoor conditions, ensuring room temperature is within 5° F of the setpoint. If

needed, the unit will briey cycle the electric heater to maintain temperature. This feature preserves the

efciency benets of a heat pump while ensuring guest comfort.

SEPARATE HEAT/COOL

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.

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.

DESK CONTROL

READY

All Friedrich digital PTACs have low voltage terminals ready to connect a desk control energy manage-

ment 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ow is reduced or low outdoor

temperatures cause the indoor coil to freeze. When the indoor coil reaches 30°F, the compressor is

disabled and the fan continues to operate based on demand. Once the coil temperature returns to 45°F,

the compressor returns to operation.

ULTRAQUIET

AIR SYSTEM

The PD- 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.

STAINLESS STEEL

ENDPLATES

Outdoor coil endplates made from stainless steel reduce corrosion on the outdoor coil common with other

coil designs.

TOP-MOUNTED

ANTIMICROBIAL

AIR FILTERS

All Friedrich PTAC return air lters feature an antimicrobial element that has proven to prevent mold and

bacterial growth in laboratory testing. PDXFT replacement lter kits feature the same antimicrobial agent.

All 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 75 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.
