will cycle on and off too rapidly, and therefore cannot control
humidity as well.
3. Clean the filter frequently (See Routine Maintenance, Page 27).
4.
Do not block the air flow to and from the unit.
5. A dirty filter or improperly set controls can affect the cooling
ability of the unit.
6. If cooling is weak and you have verified that the filter is clean
7.
Keep blinds, shades and drapes closed on the sunny side of the
room being cooled to reduce radiant heat.
8. Proper insulation helps your unit maintain the desired inside
temperature.
9. Whenever possible, shade south and west facing windows.
10. Keep window coverings away from the unit to provide free air flow.

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.
20
Digital Temperature
Readout
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.
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.
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
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 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 for “free cooling” by utilizing the already cool indoor coil to its maximum
capacity by running for 30 seconds after the compressor.
Two-Speed Wall
Thermostat Mode
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.
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
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.
Electronic
Temperature Limiting
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.
Room Freeze
Protection
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 fixtures.
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.
Digital Defrost
Thermostat
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.
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 to ensure that the room temperature is within five 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 benefits of an electric heater while maintaining the efficiency benefits of a heat pump.
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
airflow 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 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 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.
Ultra-Quiet Air
System
The new Friedrich PD series units feature an indoor fan system design that reduces sound levels without lowering airflow
and preventing proper air circulation.
High Efficiency
The Friedrich PTAC benefits from quality components and extensive development to ensure a quiet, efficient and
dependable unit.
Dual Motor
Friedrich's new dual motor design allows for the quietest and most efficient units yet.
Rotary Compressor
High efficiency rotary compressors are used on all Friedrich PTACs to maximize durability and efficiency.
Stainless Steel Endplates
Outdoor coil endplates made from stainless steel reduce corrosion on the outdoor coil common with other coil designs.
Diamonblue
Technology
Diamonblue (seacoast protection) protects the outdoor coil from harsh environments. Comes standard on all
PTAC units.
Top Mounted
Antimicrobial
Air Filters
All Friedrich PTAC return air filters feature an anti-microbial element that has proven to prevent mold and bacterial
growth in laboratory testing. PDXRTA replacement filter kits feature the same anti-microbial agent. All filter are
washable and reusable 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 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 unit is factory configured 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.
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.
Cooling Mode
Emergency Heat Operation
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 Fan Mode for fan cycle control.
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.
Heating Mode
All units are shipped with fan mode set to continuous for cooling and cycle
for heating.
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 efficiently 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
Fan Mode
Fan Only Mode
Pressing the ‘Fan’ button will run the fan to allow for air circulation in the
room without operating the compressor or heater regardless of the room
or set temperature. The fan speed selection is made by pressing either
the ‘High Fan’, ‘Med Fan’ or ‘Low Fan’ button.
Cycle/Continuous
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 airflow 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. Dip switch 3-4 controls the fan
mode, see page 23 for setting.

monthly, and more frequently if conditions warrant. The unit must be turned
off before the filters are cleaned.
To remove the air filters, grasp the top of the filter and lift out of the front
cabinet. Reverse the procedure to reinstall the filters.
Clean the filters with a mild detergent in warm water, and allow them to dry
thoroughly before reinstalling.

28
CAUSE
●●
COMPLAINT
Unit does not cool/heat room sufficiently, or cycles
on and off too frequently
CAUSE
●●
The air conditioner has insufficient
heating capacity to match the heat
loss of the room.
●●
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.
●●
This may be due to an excessive heat
load in the room.
●●
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 cooking 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 efficiency 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 efficient, model. The actual energy usage, however, will be significantly 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 efficiency ratio (EER) and cooling
rating (Btu/h) listed on the unit's rating plate
are both agency certified.
●●
Unit runs too much
SOLUTION
This may be normal for higher efficiency (EER) air conditioners.
