Air Conditioner Features
This unit has many features. The user must be familiar with these features in order to properly
service the unit.
Compressor Restart Delay
This feature extends the overall life of compressor by preventing the short-cycling of the air
conditioner. When the compressor restarts, the unit is designed to give a minimum of 3 minutes to
equalize the refrigerant pressures for optimizing cycling.
Memory
If power is lost, all of the control settings (mode, fan speed, on/off and configuration) are stored.
When power is restored, the unit will start back up in the mode and configuration it was in before
power was lost.
Automatic Evaporator Freeze Protection
To keep the evaporator from freezing, the compressor is turned off and the indoor fan is turned
on when the evaporator temperature is too low. If the evaporator temperature is not too low, this
function is off.
Automatic Quick Warm-up
(heat pump models only)
If the room temperature falls to 8
°
F/4.5
°
C below the setpoint temperature, the reverse cycle heat is
shut off and the electric strip heat is turned on for one cycle, until the setpoint is reached.
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. LED for POWER is the unit ON/OFF status
LED. If the unit is in ON mode, the LED will be green. If the unit is OFF, the LED will be off.
High Temperature Protection In Heating Operation
The compressor and/or electric heater will be switched off to prevent damage if the indoor
temperatures are too high or the indoor temperature sensor fails.
