1.4 Programme Dry Function
Programme dry function removes humidity while preventing the room temperature from lowering.
Since the microcomputer controls both the temperature and air flow volume, the temperature
adjustment and fan adjustment buttons are inoperable in this mode.
In Case of
Inverter Units
The microcomputer automatically sets the temperature and fan settings. The difference between
the room temperature at startup and the temperature set by the microcomputer 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.
