Basic Fan Speed can be manually adjusted (Lo, Hi) by using the Fan Speed Selection Button/Pad at Remote Control or
Main Unit (Touch Control Panel).
7.2
Cooling Mode Operation
•
Cooling in operation according to Remote Control or Main Unit ( Touch Control Panel) setting.
7.2.1 Time delay Safety Control ( 3 Minute)
•
When the compressor is stopped by Operation Switch at the Remote Control or Main Unit (Touch Control Panel), it restart
after 3 minutes when the Operation Switch at the remote Control or Main Unit (Touch Control Panel) is turned ON.
•
When the setting temperature is reached during cooling operation, the compresor stops and it will not startfor 3 minutes.
•
Protection of compressor to balance the pressure in the refrigeration cycle for 3 minutes.
7.2.2 7 minutes Time Saved Control
•
The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is between the
compressor On temperature and OFF temperature.
7.2.3 Starting Current Control
•
When the compressor and fan motor are simultaneously started, the fan motor will operate 1.6 second later.
7.2.4 Freeze Prevention Control
If the temperature of the indoor heat exchanger falls con-
tinuously below 1
tinuously below 1
