2. Low Operation
① Control Summary
(a) Dehumidifying operates continuously regardless of the humidity.
(b) The constant compressor, cool air and warm air fans operate continuously.
(c) By reducing the rank of the blower fan compared to high operation, the dehumidifi cation function is decreased
during operation.(Creating low noise)
Target part
