Front shutter [1.1], can be
hinged down for filter
changing. The front cover
is re-moved completely
for maintenance work.
For simple opening and
closing of the front
shutter.
W1 and W2: For power
connection and room air
control. Ready-cabled in
the ventilation unit. W3:
Connection for external
component, e.g. CO
2
sensor or external
operating display.
Ventilation unit can be
hung from the wall
bracket. Includes rubber
buffer [4.1].
Bypass connection
cover.
Filters coarse dirt out of
the outside air and
exhaust air.
Filters the smallest dirt out
of the outside air, e.g.
pollen.
The heat transfer between
the exhaust air and supply
air flows happens in the
heat exchanger.
Conveys fresh air
into the living area.
Connection for drain
hose. For dispersing the
condensation that has
collected in the heat
exchanger.
Measures the tempe-
rature of the outgoing air
directly after the heat
exchanger.

parameter.
Sensor for detecting
carbon dioxide "CO " The
2
supply of fresh air is done
dependant on the level of
CO -present in the room.
2
Hygrostat for detecting
the relative humidity. The
supply of fresh air is done
dependant on the level of
relative humidity in the
room.
Ventilation unit switches
off when the front shut-ter
[1.1] is hinged down.
Bypass can
be adjusted
manually.
Cassette is a summer
substitute for heat
exchanger [8].
