a. Anti-Freezing Control
•
When the temperature of the indoor heat exchanger becomes low, the compressor operating frequency is reduced and
stopped when the temperature falls to lower than 2°C continuously for 6 minutes. This is to prevent freezing of indoor heat
exchanger. When the temperature rises to 10°C or above, the compressor restarts with 3 minutes. The compressor
operating frequency will resume to normal when the temperature reaches 14°C.

operating frequency will resume to normal when the temperature reaches 14°C.
•
Indoor fan speed will increase when the temperature falls and it will resume to original speed when the temperature
increases to 14°C for 5 minutes continuously.
increases to 14°C for 5 minutes continuously.
Note: The above phenomenon occurs when the fan is running at Me+ or below.
b. Anti-Dew Formation Control
•
When the following conditions occurs for 20 minutes continuously, anti-dew formation is controlled:
1. Indoor intake air temperature is 24°C or above.
2. Outdoor air temperature is less than 30°C.
3. Remote control setting temperature is less than 25°C.
•
During anti-dew formation control, compressor operates at 36 Hz (CS-G95KE) or 44 Hz (CS-G125KE) and airflow direction
vane move slightly (as shown in Airflow Direction Control). Indoor fan speed will shift as below:

After 420 minutes from the start of operation, the operation timer counting is restarted from “0”.
d. High Pressure Control at Minimum Frequency Control
•
When the outdoor air temperature increases to 38.6°C, compressor operating frequency reduces to minimum of 31 Hz.
Compressor operating frequency will resume to normal when outdoor air temperature decreases to 37.8°C.
Compressor operating frequency will resume to normal when outdoor air temperature decreases to 37.8°C.
