Adjusting the air volume
The air flow rate of the Vitovent 300 is
preset at the factory to the following
values:
Version: 180 m
3
/h 300 m
3
/h 400 m
3
/h
Reduced mode:
(Display "1") 75 m
3
/h 100 m
3
/h 100 m
3
/h
Standard mode:
(Display "2"- basic air change) 100 m
3
/h 150 m
3
/h 200 m
3
/h
Demand-dependent mode:
(Display "3") 150 m
3
/h 225 m
3
/h 300 m
3
/h
These settings can be adjusted to suit
the local conditions.
For this observe that the setting for
reduced mode must always be lower
than the setting for standard mode,
which in turn must be lower than the
setting for the demand mode.
The air flow rate of the higher operat-
ing mode will be selected automati-
cally if one of these conditions is not
met during the setting process. Note
The air flow rates that the Vitovent
can actually achieve are subject to
the layout of the air duct system and
the pressure drop (cleanliness) of the
filters.
To maintain the selected air volume
(on the ventilation and the extract air
sides) irrespective of the system pres-
sure drop, the speed of both fans is
automatically adapted.
