9.1 Cooling Operation

Cooling Operation can be set using remote control.

This operation is applied to cool down the room temperature to the setting temperature set on the
remote control.

The remote control setting temperature, which takes the reading of intake air temperature sensor, can
be adjusted from 16

℃

to 30

℃

During cooling operation, the compressor will stop and restart as shown in figure below:
