Vort HRW 20 HCS
This model features a relative humidity sensing circuit that
is factory set at 70%; when relative humidity exceeds this
value, the appliance starts automatically.
The installer can choose from 4 alternative values for the
humidity threshold (using the slide-switch shown in fig.41):
60%, 70%, 80%, 90%.
When the sensor starts the appliance it runs in extractor
mode at maximum speed until room humidity level falls
below the threshold value. Once humidity is below the thre-
shold value the appliance resumes its previous operating
mode.
The sensor is active also when the appliance is on stand-
by, i.e. with the speed selector set to 0
