Perfect Aire 2PTC12A-3.0, User Manual

Page: 3 / 16

High Pressure Protection
:
The unit will shut off
automatically when the pressure in the system is over
638 psi and within 10 minutes, after the compressor
turns off, the unit will restart when the pressure turns
back below 551 psi. This protection can effectively
avoid the burst and leakage of pipes, lessen the
system failures and prolong the service life.
Failure Tolerance
:
If the unit is in protection mode
less than 4 times in one hour, the accumulation times
will reset to avoid system failure. Only when the unit
enters protection mode more than 4 times in one hour,
the system will fail to restart automatically and need
manual restart.
Standard Physical Dimensions
:
42" wide x 16" high x 13-3/4" deep
Replacement of older units is made easy.
Weather
-
Protected Electrical Components
:
Vital
electrical components are protected from the weather
by locating them on the indoor side of the weather
barrier.
Highly Featured Microprocessor Controls
:
Microprocessor controls are programmed to the
interface with temperature sensors to maximize
comfort conditions for the room's occupant and
provide outstanding features.
Thermistors are used to sense small changes in
temperature to give excellent room control and allow
the microprocessor to monitor and react to changing
conditions.
Automatic Emergency Heat on Heat Pump Units
:
Automatically uses electric resistance heat if the heat
pump fails
.
High-Temperature Heat Pump Operation
Protection
: Automatically protects the compressor if
heat pump is operated with high indoor coil
temperatures. Power to the outdoor fan and the
compressor are turned off if the indoor coil gets too
hot during heat pump operation to prevent damage to
the compressor.
UNIT FEATURES
This unit has many features which are different than
those found on conventional PTAC units. The servicer
must be familiar with these features in order to properly
handle the following:
LCDI Cords
:
Underwriters Laboratories and the
National Electric Code (NEC) require power cords
that sense current leakage and can open the
electrical circuit to the unit on units rated at 250 volts
or less. In the event that unit does not operate, check
the reset button located on or near the head of the
power cord as part of the normal troubleshooting
procedure.
LCDI power Cord
Automatic 3-minute compressor lockout
:
After
the compressor cycles off, it will not restart for three
minutes.
Random restart delay
:
To help eliminate power
surges after a power outage, the unit is equipped with
a two to four minute random restart delay feature.
Whenever the unit is plugged in with the master
switch turned on and the mode switch set in the cool
or heat mode, a random restart will occur. A random
restart condition can be avoided by setting the mode
switch in the fan only or off position before applying
power to the unit.
Indication LEDs
:
The control panel has LEDs that
correspond to fan operation and to indicate unit
status. The LEDs next to the selections
ON
/ OFF, FAN , COOL, and HEAT indicate
the
operation.
