The function is available only on models
equipped with a RH sensor. The function

according to the normal moisture load caused
by a person, for example, when a shower
adds extra moisture to the residence. If the
relative humidity of residence rises above 60%
over a longer period, the set airflows must be
increased, and the reason for the high level of
moisture investigated.
The function level can be set from Smart
shortcuts / Auto humidity control menu.
