13 Protection Control
13.1. Freeze Prevention Control
• After compressor starts operation for 4 minutes, the outdoor unit will stop its operation if indoor pipe temperature falls below 2ºC
for 6 minutes.
• After 3 minutes stops, compressor restarts operation if indoor pipe temperature is 3ºC or more.
• This phenomenon is to protect the indoor heat exchanger from freezing and to prevent higher volume of refrigerant in liquid from
returning to the compressor.
13.2. Dew Form Prevention Control
• During Cooling Operation, dew form prevention control activates if:
• Indoor temperature falls between 24ºC and 30ºC.
• Compressor and thermostat is ON.
• Indoor fan speed is Low speed.
• Setting temperature is less than 25ºC.
• During dew form prevention control, the louver is fixed at 30º.
• Fan speed and angle of horizontal louver (vertical airflow angle) will be adjusted accordingly in this control.
- Fan speed will be increased slowly if the unit is in quiet mode but no change in normal cooling mode.
- The angle of horizontal louver will be changed as below figure.
Note:
A = Normal operation angle of rotation
B = Dew prevention angle of rotation
Horizontal Louver Angle
During dew prevention, the horizontal louver angle in Auto-control are as below figure.
During dew prevention, the horizontal louver angle in Manual are as below figure.
• Dew prevention control will be cancel when:
- Any one of the condition above does not comply.
