• When the dehumidification operation is set by the remote controller, the intake air temperature is detected and the set-
ting temp. is automatically set according to the intake air temperature.
Intake air Temp.
26°C ≤ intake air temp.
24°C ≤ intake air temp.< 26°C
22°C ≤ intake air temp. < 24°C
18°C ≤ intake air temp. < 22°C
intake air temp. < 18°C
• When intake air temp. is 1 C above the setting temp., condition of compressor is same as in cooling mode operation.
• When intake air temperature reaches 1 C below the setting temp., compressor operates in step1~step3 and the indoor
fan speed again operates at low speed or comes to a stop.
