Domestic ventilation system
The domestic ventilation system compri-
ses the central ventilation unit
Vitovent 300, an air duct system with
silencers for outdoor air/ventilation air
and extract air/exhaust air, as well as air
outlets for ventilation and extract air.
Fresh air enters the living rooms and
bedrooms via ventilation air apertures.
Stale air from rooms where moisture and
odours are created (e.g. kitchen, bath-
room, WC) is routed away via the extract
air apertures.
Heat recovery
The extract air is routed through a coun-
tercurrent heat exchanger for the pur-
pose of heat recovery. This preheats the
fresh outdoor air without coming into
direct contact with the stale extract air.
To ensure heat recovery is as effective
as possible, keep windows and doors
closed while heating. This also applies to
doors to ancillary and cellar rooms that
are not included in the domestic ventila-
tion scheme.
Bypass
Appliances with a maximum air flow rate
of 300 m3/h and 400 m3/h have an inte-
gral temperature-controlled, motorised
bypass damper.
Subject to the outside temperature, this
bypass switches automatically between
operation with and without heat recov-
ery.
In operation without heat recovery, all
the outdoor air is routed past the heat
exchanger, so that in summer the cool
outdoor air is not heated by the extract
air.
However, a bypass cannot achieve the
same efficiency as active cooling.
Frost protection circuit
With heat recovery, the extract air is
cooled in the countercurrent heat
exchanger, which creates condensate.
The frost protection prevents the extract
air side of the countercurrent heat
exchanger from icing up as a result of
this condensate.
With this frost protection, the outdoor air
flow rate is regulated subject to the out-
door air temperature and the pressure at
the heat exchanger. Initially, the outdoor
air flow rate is reduced to defrost the heat
exchanger.

Device description
5592 694 GB

7
Subject to the thickness of the ice, the
extract air flow can be stopped com-
pletely. At regularly decreasing intervals,
the appliance control unit checks
whether the ventilation air fan can be
switched back on again.
To prevent the frost protection from
responding, link an electric preheater
bank (accessory) or a geothermal heat
exchanger (on-site) into the domestic
ventilation system.
For a passive house, we generally rec-
ommend using a geothermal heat
exchanger.
Remote control
You can make all required settings at the
remote control.
The following operating programs are
available:
■ Constant reduced ventilation:
m
■ Constant normal ventilation:
s
■ Constant raised ventilation:
g
■ Operation according to time program:
"P1": Preset unchangeable time pro-
gram
"P2": Individually adjustable time pro-
gram
Display
The display either shows the current time
or the room temperature, the operating
program and messages (e.g. to change
the filter).
Commissioning
Commissioning and adjusting the
domestic ventilation system to suit local
conditions and the physical characteris-
tics of the building, plus instructions on
how to operate the system, must be car-
ried out by your heating contractor.

Example
From Monday to Friday and on Sunday,
you want to ventilate from 8:00 to
22:00 h and on Saturday from 9:00 to
23:00 h with the "normal" ventilation
stage. For the rest of the time, you want
to operate the system with the
"reduced" ventilation stage.
This requires the following control steps:
1. For Monday to Sunday ("DAILY"):
Setting the switching points 08:00 h
and 22:00 h
2. For the individual day, i.e. Saturday:
Deleting switching points 8:00 h and
22:00 h
3. For the individual day, i.e. Saturday:
