Product description
This product is a domestic ventilation unit.
3.1
Role and function
Task
The product aerates and ventilates living spaces and en-
sures a constant exchange of air with heat recovery in the
building.
Furthermore, the product guarantees the hygienically ne-
cessary minimum air exchange and prevents damage to the
building caused by moisture and mould.

The product
(5)
is the central component in controlled room
ventilation. Fresh outside air
(4)
is guided to the living rooms
and bedrooms via air intake openings
(2)
. The used air from
the kitchen, bathroom and WC is guided outside
(1)
via the
exhaust air openings

The exhaust air
(2)
from the dwelling is guided to the
product. The filter for the exhaust air cleans the exhaust
air and guides the exhaust air to the heat exchanger. The
heat exchanger extracts the heat from the exhaust air (heat
recovery). The cooled air is guided outside as exit air
(4)
.
The outside air
(1)
is guided to the product from the outside.
The filter for the outside air cleans the outside air and guides
the outside air to the heat exchanger. The heat exchanger
transfers the heat from the exhaust air to the outside air. The
heated air is guided to the dwelling as supply air
(3)
.
On summer nights, the outside temperature is often lower
than the room temperature. Through the automatic bypass,
the cooler outside air is no longer preheated by the heat ex-
changer. The bypass guides the warmer exhaust air past the
heat exchanger directly outside. The frost protection function
reduces the supply air volume flow according to demand,
which leads to an increase in the exit air temperature. This
prevents the heat exchanger from freezing. If the reduction in
the supply air volume flow is no longer sufficient, the product
switches off.
The humidity sensor records the current moisture in the
exhaust air. If you operate the product in auto mode, the
current air volume flow is regulated according to demand
