The Energy Saving Smart Operation

When the target relative humidity is reached, the unit will operate only the fan in low speed for 1 minute, then will stop for 15 minutes. The fan will then run for 1 minute to check the relative humidity.

If the relative humidity has risen above the target humidity (HS)+3%, the Kullhaus Qualis will start operating again. If the relative humidity remains below the target level, Kullhaus Qualis will fall back to sleep for an additional fan works in low speed for about 1 minute, then stop for 15 minutes.
