8.5.2. Automatic Fan Speed Control
• When set to Auto Fan Speed, the fan speed is adjusted between maximum and minimum setting as shown in the table.
− Fan speed rotates in the range of Hi, Me and Lo-.
− Deodorizing Control will be activated.
− Auto Fan Speed during cooling operation:
1. Indoor fan will rotate alternately between off and on as shown in below diagram.
2. At the beginning of each compressor start operation, indoor fan will increase fan speed gradually for deodorizing
purpose.
3. For the first time the compressor operate, indoor fan will be switched to Hi fan speed from Lo- after 70 seconds from the
start of compressor. This cause the room temperature to achieve the setting temperature quickly.
4. During compressor stop, indoor fan will operate at Lo- for the beginning 20 seconds to prevent higher volume of
refrigerant in liquid form returning to the compressor.
5. After the compressor at turn off condition for 3 minutes, indoor fan will start to operate at Lo- to circulate the air in the
room. This is to obtain the actual reading of the intake air temperature.
6. When the compressor resume operation, indoor fan will operate at Me fan speed (after 70 seconds from the restart of
compressor) to provide comfort and lesser noise environment.
