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 increase +40 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

a)Control 1

•During anti-dew formation control, compressor operates at frequency shift as shown below when indoor fan speed is less than Me.

•This control is cancelled after started for 420 minutes, or remote control setting temperature or fan speed setting is changed.

b)Control 2

•When the following conditions occurs for 20 minutes continuously, anti-dew formation is controlled and air vane change Horizontal vane shift to 2nd position and Vertical vane shift to center position.

1.Indoor intake air temperature is 25°C or above and less than 29°C.

2.Outdoor air temperature is less than 30°C.

3.Air vane control: Manual Horizontal Airflow and Manual Vertical Airflow.

4.Fan speed is quiet Lo.
