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 starts operation, indoor fan speed increases gradually for deodorizing
purpose.
3 For the first time the compressor operates, 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 stops, 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 turned off 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 For the resume of compressor operation, indoor fan will operate at Me fan speed to provide comfort and
lesser noise environment, after 70 seconds from the restarts of compressor.
