guests rated Friedrich digital ptac
the quietest. here’s why–
DIGITAL TEMPERATURE
READOUT |
Room temperature is digitally monitored, providing for more precise control 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. |
|
|
REMOTE CONTROL
OPERATION |
All 2008 “D” model PTAC units can be controlled by a wireless hand held remote control. The remote
control places all of the controls of the PTAC unit conveniently in the palm of your guest’s hands. The
remote can operate from distances up to 25 feet away. The remote is sold seperately as accessory PDXRC. |
|
|
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 energizing
or stopping immediately. Upon call for cooling or heating, the unit fan will run for fi 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 new 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. |
|
|
CONSTANT COMFORT
ROOM MONITORING |
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 benefi ts to a remote mounted thermostat without the complication or cost of a wallmounted
thermostat. |
|
|
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 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 fi 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. |
|
|
DIAMONBLUE
ANTICORROSION
PROTECTION |
Diamonblue corrosion protection comes standard on all models. Diamonblue protects the outdoor
coil against deterioration, and extends the life of the unit. |
|
|
DIGITAL DEFROST
THERMOSTAT |
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 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 fi 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 benefi ts of an electric heater while maintaining the effi
ciency benefi ts of a heat pump. |
|
|
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
constantly circulates the air while 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 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 airfl 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 |
Friedrich PD series units feature an indoor fan system design that reduces sound levels without lowering
airfl 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. |
|
|
SINGLE MOTOR |
Friedrich’s single-motor design allows for enhanced outdoor airfl ow and simplifi es the unit design without
the need for redundant components. |
|
|
ROTARY COMPRESSOR |
High effi ciency rotary compressors are used on all Friedrich PTACs to maximize durability and effi ciency. |
|
|
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 need for
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. |
|
|
TOP-MOUNTED
ANTIMICROBIAL
AIR FILTERS |
All Friedrich PTAC return air fi lters feature an antimicrobial element that has proven to prevent mold
and bacterial growth in laboratory testing. PDXFT replacement fi lter kits feature the same antimicrobial
agent. All fi 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 70 CFM of outside air into the conditioned space. The
outdoor air passes through a washable mesh fi lter to prevent debris from entering the airstream. |
