OFF temperature is the setting temperature minus 0.5°C.
• When the room temperature rises over the compressor ON temperature, the operation mode is switched to the
cooling mode.
• When the room temperature falls between the compressor ON temperature and OFF temperature, the opera-
tion mode is switched to the Soft Dry Operation.
In this temperature range, 10min. Dry Operation, 7min operation OFF. During 10min Dry operation, if the room
temperature falls below compressor OFF temperature, Compressor OFF.
• In micom dehumidify mode, control of fan speed is as following.
