Function 121
7.3 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.
