AIR CONDITIONER FEATURES
Compressor Restart Delay
This feature extends the overall life of compre-
ssor by preventing the short-cycling of the air
conditioner.When the compressor restarts,the
unit is designed to give a minimum of three
minutes to have a time of equalizing the refrig-
erant pressures for optimizing cycling.
Memory
The unit has memory .If power is lost,all of the
control settings(mode,fan speed,on/off and
configuration) are remembered.So 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
Automatically to keep the evaporator from
freezing,the compressor is tuuned off and the
indoor fan is turned on when the evaporator
temperature is too lower.If the evaporator
temperature is not too lower this function is off.
Automatic Quick Warm-up (for heat pump
models only)

If the room temperature falls to 4.5 C/8 F
