Auto Fan Speed during Soft Dry operation.
1 Indoor fan will rotate alternately between off and Lo-.
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.
12.4.3 Manual 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.
12.4.4 Indoor 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.
12.5 Outdoor Fan Speed Control
There is only one speed for outdoor fan motor. (Applicable for CU-C9MK, CU-C12MK and CU-C18MK)
There is 2 speeds for outdoor fan motor. Outdoor fan speed can be changed to Hi or Lo according to outdoor
temperature. (Applicable for CU-C24MK and CU-C28MK).
For Cooling and Soft Dry operation, when outdoor temperature reaches to 31°C (Hi-speed), 29°C (Lo-speed).
(Applicable for CU-C24MK and CU-C28MK).
When air conditioner is turned on, the compressor and the outdoor fan will operate simultaneously.
Likewise, both compressor and outdoor fan will stop at the same time if the unit is turned off.
12.6 Vertical Airflow Direction Control
12.6.1 Auto
Control
When the vertical airflow direction is set to Auto using the remote control, the louver swings up and down as
shown in the diagram.
When stops operation using the remote control, the discharge vent is reset and stops at the closing position.
During Cooling operation or Soft Dry operation, indoor fan motor may stop to rotate at certain periods. At that
condition, the louver will stop swinging.
