8.2.2.3. Anti-Freezing Control
1. When indoor heat exchanger temperature is lower than 2°C continuously for six minutes, compressor will stop operating.
2. Compressor will resume its operation three minutes after the indoor heat exchanger is higher than 10°C.
3. At the same time, indoor fan speed in20 rpm compared to its normal operation.
4. If indoor heat exchanger temperature is higher than 10°C for five minutes, the fan speed will return to its normal operation.
8.2.2.4. Anti-Dew Formation Control
1. When indoor fan speed is set at Me- or slower, the compressor operating frequency is regulated by operation time to prevent
fog discharged from indoor as shown in below table.

2. After 420 minutes, the operation restarts again from the beginning.
3. The operation will restart the above control whenever remote controller setting temperature or fan speed setting is changed.
8.2.3. Protection Control For Heating Operation
8.2.3.1. Intake Air Temperature Control
Compressor will operate at Max freq 67 Hz if either one of the below conditions occur:
1. When the indoor intake air temperature is less than 20°C and remote control setting fan speed is lower Me-.
2. When the indoor intake air temperature is 30°C or above.
