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.

3.Coil frost prevention

Coil frost prevention is as same as COOL mode. (2-1.3.)

The indoor fan maintains the actual speed of the moment. However ,when coil frost prevention works while the compressor is not operating, its speed becomes the set speed.

4.Low outside temperature operation

Low outside temperature operation is as same as COOL mode. (2-1.4.)
