Friedrich PTAC Digital Control and Unit 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 benefit to the owner.

Digital Temperature

By digitally monitoring desired room temperature the room is controlled more precisely than conventional systems.

Readout

The large, easy to read LED display can show either set-pointor actual room temperature as selected by owner.

 

 

 

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

One-TouchOperation

‘Cool’ buttons without the confusing power up sequence of some controls. One-touchcontrol takes guesswork out

 

of unit control delivering a more enjoyable experience and eliminating front-deskcalls.

 

 

Three Fan Speeds

The Friedrich PTAC/PTHP units feature three fan speeds for the user to select from. This allows the user to

properly match the amount of airflow for their comfort level and also deliver's quiet performance.

 

 

 

Individual Mode and

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

Fan Control Buttons

comfort than other systems.

 

 

 

 

The fan start and stop delays prevent abrupt changes in room acoustics due to the compressor energizing or

Quiet Start/Stop

stopping immediately. Upon call for cooling or heating the unit fan will run for five seconds prior to energizing the

Fan Delay

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.

 

 

Two-SpeedWall

When connected to a wall thermostat the user can select from high or low fan speed at the thermostat, unlike

competitive models that have only one speed selection. This allow more comfortable and quieter operation.

Thermostat Mode

Requires the use of Friedrich remote thermostat RT6 or equivalent thermostat with two speed fan output.

 

 

 

Remote Thermostat

Some applications require the use of a wall mounted thermostat. All new Friedrich PTACs may be switched from

Operation

unit control to remote thermostat control easily without the need to order a special model or accessory kit.

 

 

Internal Diagnostic

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

Program

problems.

 

 

 

 

The self diagnosis program will also store error codes in memory if certain conditions occur and correct

Service Error Code

themselves such as extreme high or low operating conditions or activation of the room freeze protection feature.

Storage

Storing error codes can help properties determine if the unit faced obscure conditions or if an error occurred and

 

corrected itself.

 

 

Electronic

By limiting the operating range the property can save energy by eliminating “max cool” or “max heat” situations

common with older uncontrolled systems. The new electronic control allows owners to set operating ranges for

Temperature Limiting

both heating and cooling independently of one another.

 

 

 

 

When the PTAC senses that the indoor room temperature has fallen to 40° F the unit will cycle on high fan and

Room Freeze

the electric strip heat to raise the room temperature to 46° F 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

Protection

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 fixtures.

 

 

Random Compressor

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

Restart

compressor delay will range from 180 to 240 seconds.

 

 

 

Digital Defrost

The Friedrich PTAC 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

Thermostat

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