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 adjustment buttons are inoperable in this mode.
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 the dry mode with an appropriate capacity for each zone to
maintain the temperature and humidity at a comfortable level.
temperature at start-up
59
The fan speed is controlled automatically within the following steps.
Cooling: L tap – MH tap (same as AUTOMATIC)
Heating: ML tap – M tap ~ MH tap (depending on the model)
