When the room temperature reaches the desired temperature, the high-frequency noise and the noise from the outdoor unit are reduced.
■ Solution or Settings
■ Summary
- If the difference between the room temperature and the desired temperature is high, it increases the motor speed and the rotating speed of the compressor
at rapid speed, which may generate a fine high-frequency noise during the initial operation.
When the room temperature reaches the desired temperature, the high-frequency noise and the noise from the outdoor unit are reduced.
