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.

1. Thermostat control
Thermostat is ON or OFF by difference between room temperature and set temperature.

2. Indoor fan speed control
(1) Indoor fan operates at the set speed by FAN SPEED CONTROL button.
In Auto the fan speed is as follows.
Set temperature minus room temperature: 3.6 degrees or more······································ High
Set temperature minus room temperature: Between 0.4 and 3.6 degrees ···················· Med.
Set temperature minus room temperature: less than 0.4 degrees···································· Low

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.
When thermostat OFF (compressor OFF) fan speed becomes Very Low.
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 it’s speed becomes the set speed.
