3. Appliance description
3.1
Function description
subject to demand, the humid, odorous air is transported out
of the bathroom and wC to the outdoors or into central extract
air shafts. This creates slight negative pressure in the apart-
ment. due to this negative pressure, fresh, filtered air flows in
of its own accord through air apertures in the external walls of
living spaces and bedrooms. overflow apertures in the doors
create an air connection between the supply and extract air
areas.
depending on the airtightness of the building, decentralised
external wall apertures in supply air areas are not essential. In
some cases, natural infiltration due to the permeability of the
building envelope provides sufficient fresh air.
Appliance with humidity sensor
when the humidity sensor detects a demand or when you
change to full load with a switch, the appliance changes to
the maximum possible air flow rate.
