Press ON/OFF button.
The OPERATION indicator lamp goes out.
The microcomputer functions determining the
appropriate room temperature and humidity, and the
operating cycles of the external compressor and
interior fan, which allow maintaining these levels
based on the ambient temperature and humidity at the
time of switching on this function.
Note:
The PROGRAM DRY function is designed primarily
for dehumidification and not for lowering room
temperature – but remember a dehumidified room will
always “feel” cooler than a humid one.
PROGRAM DRY operation is not possible in ambient
below 18°C.
There is no need to set the THERMOSTAT SETTING
selector or FAN SPEED selector as PROGRAM DRY
operates independently of them.
