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 benifit to the owner.
DIGITAL TEMPERATURE
READOUT
By digitally monitoring the desired room temperature, the room is controlled more precisely than con-
ventional systems. The large, easy-to-read LED display can show either the set point or actual room
temperature as selected by owner.
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 energiz-
ing 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 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.
Factory run-tested units reduce problems in the field.
ELECTRONIC
TEMPERATURE
LIMITING
By limiting the operating range, the property can save energy by eliminating “max cool” or “max heat” situ-
ations common with older uncontrolled systems. The new electronic control allows owners to set operat-
ing 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
5
0
°
F, the unit will cycle on the fan
(high) and the electric strip heat to raise the room temperature to
55
°
F, and then cycle off again. This
feature works regardless of the mode selected and can be turned off.
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 1
2
0 to 240 seconds.
CONDENSATE REMOVAL
SYSTEM
Condenser fan utilizes slinger ring technology to pick up condensate from the base pan and disperse it on
to the condenser coil where it evaporates. This helps to cool the coil and increase the energy ef
fi
ciency
of the unit.
