• 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 SLo after 70 seconds from the
start of compressor. This cause the room temperture to achieve the setting temperature quickly.
4. During compressor stop, indoor fan will operate at SLo 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 SLo 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.
• Auto Fan Speed during Soft Dry operation:
1. Indoor fan will rotate alternately between off and Lo-.
2. At the beginning of each compressor start operation, indoor fan will increase fan speed gradually for deodorizing purpose.
3. When compressor at turn off condition for 6 minutes, indoor fan will start fan speed at Lo- to circulate the air in the room.
This is to obtain the actual reading of intake air temperature.
• Auto Fan Speed during Heating operation.
1. Indoor fan will rotate in the range of SLo → Me according to the heat exchanger temperature.
