Difference between room temperature and set temper- ature during operation

2-2. DRY ( ) OPERATION

Set temperature is as shown on the right chart.

The system for dry operation uses the same refrigerant circuit as the cooling circuit.

The compressor and the indoor fan are controlled by the room tem- perature.

By such controls, indoor flow amounts will be reduced in order to lower humidity without much room temperature decrease.

2.Indoor fan speed control

Indoor fan operates at the set speed by FAN SPEED CONTROL button. When thermostat OFF (compressor OFF) fan speed becomes Very Low.

In AUTO the fan speed is as follows.
