A number of important conditions must
be met to ensure the ventilation system
functions properly:
■Do not place objects such as for
example cabinets in front of the control
unit.
■Ensure a sufficient supply of air. For
example, open a small window or any
trickle vent in a window, window frame
or sliding door.
■If the home is fitted with non-lockable
air openings, such as trickle vents above
the windows or gaps under doors, then
leave these open. Do not cover or block
them.
■Ensure that there is no powered
extractor hood connected to the
ventilation system.
4.1 Setting ventilation level
A manual ventilation mode cannot be set on
all control units. This is only possible on a
control unit set by the installer as the main
control unit or as a CO2controller.
In manual ventilation mode,
ventilation is not controlled on the
basis of the CO2levels.
A manual ventilation mode
remains active for up to 12 hours.

bright, high, medium, low, warning, off.
