Program Dry Operation
Outline
Program dry operation removes humidity while preventing the room temperature from lowering.
Since the microcomputer controls both the temperature and airflow rate, the temperature
adjustment and
FAN
setting buttons are inoperable.
Details
The microcomputer automatically sets the temperature and airflow rate. The difference between
the room thermistor temperature at start-up and the target temperature is divided into two zones.
Then, the unit operates in an appropriate capacity for each zone to maintain the temperature and
humidity at a comfortable level.
