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.
Detail
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.
