During operation. The speed of the fan is controlled in order to optimise product
operation.
This is the case immediately after the main power supply switch is turned on and
means that the user interface is in normal condition. This continues for 1 minute.
This is to prevent refrigerant from remaining in the compressor. The unit will stop
