(Noise level: Level 1 > Level 2 > Level 3)
- Auto mode : General and silent modes switch to each other automatically for day and night.
- External contact : Configure this option if using an interface module (MIM-B14).
Silent mode turns on if the external contact is on.
▪ Control specifications in detail
- The maximum compressor frequency and outdoor fan RPM decrease according to the specified level.
- Silent mode automatically turns on according to the day/night temperature pattern if Auto mode is on.
If External contact is configured, silent mode turns on when the contact is on.
▪ Notes
