When this value of relative humidity is exceeded, the
dehumidifier is started during the enable time of his
timing program.
When this value of relative humidity is exceeded, the

One-sided hysteresis around the switching threshold
(switch off point is by this value below DE4)

mand signal will be soonest after this delay time.
Dehumidification is also allowed outside of cooling
period (Y/N)
Maximum run time for dehumidifier
