Auto Fan Speed during Heating operation.
Indoor fan will rotate in the range of SLo
→
Me according to the heat exchanger temperature.
(For A9PKD and A12PKD)
(For A18PKD, A24PKD and A28PKD)
13.5.3 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.
13.5.4 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.
13.6 Outdoor Fan Speed Control
•
There is only one speed for outdoor fan motor. (Applicable for CU-A9PK and CU-A12PK)
•
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-A18PK, CU-A24PK and CU-A28PK).
•
For Cooling and Soft Dry operation, when outdoor temperature reaches to 31°C (Hi-speed), 29°C (Lo-speed).
(Applicable for CU-A18PK and CU-A24PK).
•
For heating operation, when outdoor temperature reaches to 13.5°C (Hi-speed), 15.5°C (Lo-speed). (Applicable
for CU-A18PK, CU-A24PK and CU-A28PK).
•
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.
