Operation
Cooling mode operation
• 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.

Healthy Dehumidification mode operation
• 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 s1.0°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.
