Friedrich Digital Control 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. The large, easy |
|
Readout |
to read LED display can show either 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 guesswork out of unit control delivering a more |
||
|
enjoyable experience and eliminating front-desk calls. |
|
|
|
|
Individual Mode and |
By having separate control buttons and indicators for both fan and mode settings the Friedrich digital control eliminates the confu- |
|
Fan Control Buttons |
sion of previous digital PTACs. The accurate temperature setting provides greater guest comfort than other systems. |
|
|
|
|
Quiet Start/Stop |
The fan start and stop delays prevent abrupt changes in room acoustics due to the compressor energizing or stopping immediately. |
|
Upon call for cooling or heating the unit fan will run for five seconds prior to energizing the compressor. Also, the fan off delay allows |
||
Fan Delay |
||
for “free cooling” by utilizing the already cool indoor coil to its maximum capacity by running for 30 seconds after the compressor. |
||
|
||
|
|
|
Remote Thermostat |
Some applications require the use of a wall mounted thermostat. All new Friedrich PTACs may be switched from unit control to |
|
Operation |
remote thermostat control easily without the need to order a special model or accessory kit. |
|
|
|
|
Wireless Remote |
Guests can adjust the temperature and mode of the unit through the use of an optional hand held wireless remote, improving guest |
|
Control Ready |
comfort and relaxation. |
|
|
|
|
Internal Diagnostic |
The new Friedrich digital PTAC features a self diagnostic program that can alert maintenance to component failures or operating |
|
Program |
problems. The internal diagnostic program saves properties valuable time when diagnosing running problems. |
|
|
|
|
Service Error Code |
The self diagnosis program will also store error codes in memory if certain conditions occur and correct themselves such as ex- |
|
treme high or low operating conditions or activation of the room freeze protection feature. Storing error codes can help properties |
||
Storage |
||
determine if the unit faced obscure conditions or if an error occurred and corrected itself. |
||
|
||
|
|
|
Constant Comfort |
The on-board processor monitors time between demand cycles (heat or cool) and will cycle the fan every 9 minutes to sample the |
|
room condition and determine if the desired conditions are met. This allows the room to have similar benefits to a remote mounted |
||
Room Monitoring |
||
stat without the complication or cost of a wall mounted thermostat. |
||
|
||
|
|
|
Electronic Temperature |
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 both heating and cooling independently |
||
Limiting |
||
of one another. |
||
|
||
|
|
|
Room Freeze |
When the PTAC senses that the indoor room temperature has fallen to 40°F the unit will cycle on high fan and 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 |
||
Protection |
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 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 compressor delay will range from |
||
Restart |
||
180 to 240 seconds. |
||
|
||
|
|
|
Digital Defrost |
The new 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 save energy and reduces operating costs. The digital |
||
Thermostat |
||
thermostat allows maximization of heat pump run time. |
||
|
||
|
|

920-087-04
Friedrich Digital Control Features Continued
Instant Heat |
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 associ- |
||
Heat Pump Mode |
||
ated with heat pump units. |
||
|
||
|
|
|
Even Heat Monitoring |
The digital control monitors indoor conditions to ensure that the room temperature is within five degrees of the setpoint. If neces- |
|
sary the unit will cycle the electric heat to maintain the temperature. This feature ensures guest comfort by delivering the heating |
||
|
benefits of an electric heater while maintaining the efficiency benefits of a heat pump. |
|
|
|
|
|
The owner may choose between fan cycling or fan continuous mode based on property preference. (Note: Even heat monitor- |
|
Fan Cycle Control |
ing and quiet start/stop fan delay only operate in fan cycle mode) Fan continuous mode is used to keep constant airflow circula- |
|
tion 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. |
|
|
|
|
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 resis- |
|
tance heater. This feature ensures that even in the unlikely event of a compressor failure the room temperature can be main- |
||
|
tained until the compressor can be serviced. |
|
|
|
|
Desk Control Ready |
All Friedrich digital PTACs have low voltage terminals ready to connect a desk control energy management system. Control- |
|
ling the unit from a remote location like the front desk can reduce energy usage and requires no additional accessories at the |
||
|
PTAC. |
|
|
|
|
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 30°F the compressor is diabled and the fan continues to operate based |
||
|
on demand. Once the coil temperature returns to 45°F the compressor returns to operation. |
|
|
|
|
Ultra-Quiet Air System |
The new Friedrich PD series units feature a indoor fan system design that reduces sound levels without lowering airflow and |
|
preventing proper air circulation. |
||
|
||
|
|
|
High Efficiency |
The Friedrich PTAC benefits quality components and extensive development to ensure a quiet, efficient and dependable unit. |
|
|
|
|
Single Motor |
Friedrich’s single-motor design allows for enhanced outdoor airflow and simplifies the unit design without the need for redun- |
|
dant components. |
||
|
||
|
|
|
Rotary Compressor |
High efficiency rotary compressors are used on all Friedrich PTACs to maximize durability and efficiency. |
|
|
|
|
Auxiliary Fan Ready |
The Friedrich PTAC features a 24V AC terminal for connection to an auxiliary fan that may be used to transfer air to adjoining |
|
rooms. Auxiliary fans can provide conditioning to multiple rooms without the requirement of multiple PTAC units. |
||
|
||
|
|
|
Aluminum Endplates |
All Friedrich PTACs are built with .04" endplates made from aluminum as opposed to steel. The endplates are typically the most |
|
susceptible area for corrosion and aluminum is far more resistant to corrosion than even coated steel. |
||
|
||
|
|
|
Seacoast Protection |
Optional Seacoast protection is available to protect the outdoor coil from harsh environments. The Friedrich Seacoast process |
|
includes dipping the entire outdoor coil in a 7-step coating process that provides superior protection to only coating the fins of |
||
|
the coil. |
|
|
|
|
Top Mounted Anti- |
All Friedrich PTAC return air filters feature an anti-microbial element that has proven to prevent mold and bacterial growth in |
|
laboratory testing. PDXFT replacement filter kits feature the same anti-microbial agent. All filters are washable and reusable |
||
microbial Air Filters |
||
and are 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 70 CFM of outside air into the conditioned space. The outdoor air passes |
|
through a washable mesh filter to prevent debris from entering the airstream. |
