• Operating frequency of compressor depend on the difference of the temperature.

(= intake air Temp.- Compressor off Temp.

• Compressor off temp.= setting temp. -0.5°C

on temp. = setting temp. +0.5°C

• If compressor operates at some operating frequency, the operating frequency of compressor cannot be

changed within 30 seconds.

• Condition of compressor turned off

- When intake air temperature stay at the temperature between setting temp. -0.5°C and setting temp. 

-1.0°C for 3 minutes continuously.

- When intake air temperature reaches below the temperature of setting temp. -1.0°C.

• Compressor 2 minutes delay

- The compressor can restart minimum 2 minutes later after compressor off.

• When the dehumidification operation is set by the remote controller the intake air temperature is detected and

the setting temp. is automatically set according to the intake air temperature.

• When intake air temp reaches above the temp of setting +1.0°C, condition of compressor same as cooling

mode operation.

• When intake air temperature reaches bolow the temp of setting –1.0°C, compressor operate step1~step3 and

indoor fan speed repeatly operate low or stop.
