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 specically
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 benet to the owner.
Digital Temperature Readout
One-Touch Operation
Fan Speed Mode
Individual Mode and Fan Control Buttons
Quiet Start/Stop Fan Delay
Two-Speed Wall Thermostat Mode
Remote Thermostat Operation
By digitally monitoring desired room temperature the room is controlled more precisely than conventional systems. The large, easy to read LED display can show either set-point or 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
‘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.
The Friedrich PTAC/PTHP units feature two fan speeds and auto mode for the user to select from. This allows the
user to properly match the amount of airow for their comfort level and also deliver's quiet performance.
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.
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 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.
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. Requires the use of Friedrich remote thermostat RT6 or equivalent thermostat with two speed fan output.
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
Service Error Code Storage
Electronic Temperature Limiting
Room Freeze Protection
Random Compressor Restart
Digital Defrost Thermostat
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.
The self diagnosis program will also store error codes in memory if certain conditions occur and correct themselves such as extreme high or low operating conditions or activation of the room freeze protection feature. Storing error codes can help properties determine if the unit faced obscure conditions or if an error occurred and corrected itself.
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 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 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 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.
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.
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 operating costs. The digital thermostat allows maximization of heat pump run time.
20
Page 21
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
Separate Heat/Cool Fan Cycle Control
Emergency Heat Override
Desk Control Ready
Indoor Coil Frost Sensor
Ultra-Quiet Air System
High Efciency
The digital control monitors indoor conditions to ensure that the room temperature is within ve degrees of the setpoint.
If necessary the unit will cycle the electric heat to maintain the temperature. This feature ensures guest comfort by
delivering the heating benets of an electric heater while maintaining the efciency benets of a heat pump.
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.
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.
All Friedrich digital PTACs have low voltage terminals ready to connect a 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.
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.
The new Friedrich PD series units feature an indoor fan system design that reduces sound levels without lowering airow
and preventing proper air circulation.
The Friedrich PTAC benets from quality components and extensive development to ensure a quiet, efcient and
dependable unit.
Dual Motor
Rotary Compressor
Stainless Steel Endplates
Diamonblue Tec hn ology
Top Mounted Antimicrobial Air Filters
Filtered Fresh Air Intake
Friedrich's new dual motor design allows for the quietest and most efcient units yet.
High efciency rotary compressors are used on all Friedrich PTACs to maximize durability and efciency.
Outdoor coil endplates made from stainless steel reduce corrosion on the outdoor coil common with other coil designs.
Diamonblue (seacoast protection) protects the outdoor coil from harsh environments. Comes standard on all PTAC units.
All Friedrich PTAC return air lters feature an anti-microbial element that has proven to prevent mold and bacterial growth in laboratory testing. PDXRTA replacement lter kits feature the same anti-microbial agent. All lter are
washable and reusable and are easily accessed from the top of the unit without the removal of the front cover.
Friedrich PTAC units are capable of introducing up to 75 CFM of outside air into the conditioned space. The outdoor air passes through a mesh screen to prevent debris from entering the air stream.

The vent control lever is located on the left side of the unit, behind the front panel.
NOTE: The vent door shipping hardware must be removed before
using the vent control lever. See page 17, Figure 21, (Remove Shipping Screw from Vent Door if present).
When vent door is set to CLOSE, only the air inside the room is circulated
and ltered, See Figure 28.
When vent door is set to OPEN, some outdoor air will be drawn into room.
This may reduce heating or cooling efciency.

°F vs. °C Display
The unit is factory congured to display all temperatures in degrees
Fahrenheit (° F). To switch to degrees Celsius press the ‘Fan Only’ and ‘Low Fan’ buttons simultaneously for three seconds. The display will show a ‘C’ as acknowledgement of the change. To revert back to ° F press the ‘Fan Only’ and ‘Low Fan’ buttons simultaneously for three seconds. The display will show an ‘F’ as acknowledgement of the change.
Cooling Mode
Pressing the ‘Cool’ button while the unit is in any mode, including off,
will put the unit into cooling mode. Adjust the temperature readout to the
desired room temperature and the unit will cycle the compressor on and off to maintain a comfortable room. The compressor will come on anytime that the room temperature is 1.8° F above the desired temperature. The fan operation is dependent on the fan mode selected, either continuous or cycling. See Constant Fan Mode.
Heating Mode
Pressing the ‘Heat’ button while the unit is in any mode, including off, will put the unit into heating mode.
Heat Pump Models (PDH)
When the ‘Heat’ button is pressed initially the unit will energize the electric
resistance heat to quickly bring the room to the set temperature. When the
desired room temperature falls 1.8° F below the desired set temperature the unit will cycle the compressor on and operate as a heat pump to maintain
the room temperature while running more efciently than resistance heat
only models. If the room temperature should fall more than 5° F from the set temperature the unit will run the resistance heater. The fan operation is dependent on the fan mode selected, either continuous or cycling. Dip switch 3 controls the fan mode, see page 23 for setting.
When the outdoor coil temperature falls below 30° F for more than 2 min­utes the unit will operate the resistance heaters and not the compressor. When the outdoor coil temperature reaches 45° F the compressor will be allowed to operate again.
24
Heat /Cool Models (PDE)
After pressing the ‘Heat’ button, adjust the temperature readout to the
desired room temperature and the unit will cycle the resistance heat on and off to maintain a comfortable room. The heater will come on anytime that the room temperature is 1.8° F below the desired temperature. The fan operation is dependent on the fan mode selected, either continuous or cycling. Dip switch 3 controls the fan mode, see page 23 for setting.
Emergency Heat Operation
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. Dip switch 1 controls the emergency heat setting, see page 23.
Constant Fan Mode
Pressing the Constant fan mode button will provide constant fan operation in cooling or heating modes. The fan speed selection is made by pressing
either "High" or "Low" fan speed button.
Cycle/Continuous (Factory Default)
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 heat mode + cycle mode). Cycle fan will conserve energy by only operating the fan when the call for cooling
or heating is required.

nance) or remove obstruction.
● Clean the coils, (See Recommended Mainte- nance) or remove obstruction.
● Allow additional time too cool a very hot room
● Do not try to operate your air conditioner in the cooling in the cooling mode when the outside temperature is below 60º F. The unit will not cool properly, and the unit may be damaged.
● Since the fan does not circulate the room air continuously at this setting, the room air does not mix as well and hot (or cold) spots may result. Using the continuous fan setting is recommended to obtain optimum comfort levels.
● Check the cooling capacity of your unit to en- sure it is properly sized for the room in which it is installed. Room air conditioners are not designed to cool multiple rooms.

COMPLAINT CAUSE SOLUTION
Unit does not cool/heat room sufciently, or cycles
on and off too frequently
COMPLAINT CAUSE SOLUTION
Unit runs too much
● The air conditioner has insufcient heating capacity to match the heat loss of the room.
● This may be due to an excessive heat load in the room.
● This may be normal for higher ef-
ciency (EER) air conditioners.
● Check the heating capacity of your unit. Air conditioners are sized to meet the cooling load and heater size is then selected to meet the heating load. In extreme, northern cli­mates, room air conditioners may not be able to be used as a primary source of heat.
● If there are heat product appliances in use in the room, or if the room is heavily occupied, the unit will need to run loner to remove the additional heat.
● Be sure to use exhaust vent fans while cook- ing or bathing and, if possible, try not to use heat producing appliances during the hottest part of the day. It may also be due to an improperly sized unit.
● Depending upon the size of the room being cooled, a higher capacity air conditioner may be necessary
● The use of higher efciency components in your new air conditioner may result in the unit running longer than you feel it should . This may be more apparent, if it replaced an older,
less efcient, model. The actual energy us­age, however, will be signicantly less when
compared to older models.
● Likewise, you may notice that the discharge air temperature of your new air conditioner may not seem as cold as you may be ac­customed to from older units. This does not, however, indicate a reduction in the cooling capacity of the unit
● The energy efciency ratio (EER) and cooling rating (Btu/h) listed on the unit's rating plate
are both agency certied.
