•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.
•Auto Fan Speed during Soft Dry operation.
1 Indoor fan will rotate alternately between off and
2 At the beginning of each compressor starts operation, indoor fan will increase fan speed gradually for deodorizing purpose.
3 When compressor turned off for 6 minutes, indoor fan will start at Lo- to circulate the air in the room. This is to obtain the actual reading of intake air temperature.
12.4.3Manual Fan Speed Control
•Manual fan speed adjustment can be carried out by using the Fan Speed selection button at the remote control.
•There are 3 types of fan speed settings: Lo, Me, Hi.
12.4.4Indoor Fan Motor rpm Abnormal Control
•Immediate after the fan motor is started, rpm abnormal control is performed every second.
•During fan motor on, if fan motor feedback ≥ 2550 rpm or < 50 rpm continuously for 10 seconds, the fan motor error counter increased; fan motor is then stopped and restarted. If the fan motor error counter increased to 7, then air conditioner will stop operation.
