AIR CONDITIONER FEATURES
This unit has many features. The servicer must be
familiar with these features in order to properly
service the unit.
● Compressor Restart Delay
This feature extends the overall life of the
compressor by preventing the short-cycling of the
air conditioner. When the compressor restarts, the
unit is designed to have a delay of at least three
minutes to have enough time to equalize the
refrigerant pressures for optimal cycling.
● Memory
The unit has memory. If power is lost, all of the
control settings (mode, fan speed, on/off and
configuration) are remembered. When power is
restored, the unit will start back up in the mode
(and configuration) it was in when power was lost.
● Automatic Evaporator Freeze Protection
To keep the evaporator from freezing when the
evaporator temperature is too low, the compressor
is automatically turned off and indoor fan is
turned on.
● Automatic Quick Warm-up
(For Heat Pump Models Only)
If the room temperature falls to 8ºF/4.5ºC below
the set point temperature, the reverse cycle heat
is shut off and the electric strip heat is turned on
for one cycle until heating is satisfied.
● LED Indicators and Buttons
The touch pad has buttons for MODE, FAN,
POWER, SETPOINT UP and SETPOINT DOWN.
It also has LEDs that correspond to the mode, fan
speed, power and setpoint operation to indicate
the unit’s status.
LEDs for HIGH, MED, and LOW indicate the fan
speed that is selected.
LEDs for FAN, COOL and HEAT indicate what
operating mode is active.
The LED for POWER indicates the unit’s
ON/OFF status.
- If the unit is in ON mode, the LED will be green.
- If the unit is OFF, the LED will be off.
Note: HEAT mode is for models with Cooling &
Heating functions only.
● High Temperature Protection in
Heating Operation
The compressor and/or electric heater will be
switched off to prevent damage where high indoor
air temperatures are present or if an error is
detected by the indoor temperature sensor. See
“HI” code on page 6.
● Unit Configuration - ºF or ºC
The unit can display in either ºF or ºC.
