Mechanical ventilation systems
Mechanical ventilation systems provide controlled ven-
tilation of detached houses or apartments.
If your Viessmann system includes mechanical ventila-
tion, the central ventilation unit can be controlled and
operated by the heat pump control unit.
Ventilation operation adapts automatically to your
requirements via a time program. "Economy mode"
and the "Holiday program" help you to save energy.
With "Intensive operation", you increase the air
changes in the building and quickly expel odours and
moisture to the outside.
The following central ventilation units are supported:
Vitovent 200-C
Vitovent 200-C is suitable for detached houses or
apartments with up to 120 m
2
of living space.
Vitovent 200-C meets the requirements for passive
house use.
The ventilation unit can either be mounted on a wall or
installed on the ceiling.
As well as being controlled by the heat pump control
unit, ventilation can also be activated by a switch or
button (bathroom switch) connected to the ventilation
unit, e.g. if you need the highest ventilation level for a
short period.
Vitovent 200-W
Vitovent 200-W is suitable for detached houses or
apartments with up to 230 m
2
of living space.
This ventilation unit is mounted on a wall.
To prevent moisture damage to the building, the venti-
lation unit adjusts the air changes automatically,
depending on the relative humidity in your rooms
(accessories required).
Vitovent 300-C
Vitovent 300-C is suitable for detached houses or
apartments with up to 90 m
2
of living space.
Vitovent 300-C meets the requirements for passive
house use.
The ventilation unit can either be mounted on a wall or
installed on the ceiling.
To ensure good air quality in your building, the ventila-
tion unit adjusts the air changes automatically, depend-
ing on the relative humidity and/or carbon dioxide con-
centration in your rooms (accessories required).
Vitovent 300-F
Vitovent 300-F is suitable for detached houses or
apartments with up to 180 m
2
of living space.
Vitovent 300-F meets the requirements for passive
house use.
This ventilation unit is installed near the heat pump
control unit.
To ensure good air quality in your building, the ventila-
tion unit adjusts the air changes automatically, depend-
ing on the relative humidity and/or carbon dioxide con-
centration in your rooms (accessories required).
In addition to actual mechanical ventilation, your rooms
can also be supplied with heat from the heat pump via
the ventilation system. This method of heating the sup-
ply air can be used as the sole heat source in buildings
with very good thermal insulation. For supply air heat-
ing, your contractor will have connected the ventilation
unit to heating circuit HC1 of your heat pump. This
means heating circuit HC1 is then a ventilation heating
circuit.
Vitovent 300-W
Vitovent 300-W is suitable for detached houses or
apartments with up to 370 m
2
of living space.
