The CO
2
control system only works when the Air 70 is set to ventilation mode 1 or 2. If the CO
2
sensor measures
an increase of the CO
2
value, the ventilation capacity is automatically increased. When the CO
2
value decreases,
the ventilation capacity will automatically be reduced again (see pictures). The factory setting (default) of the ven-
tilation modes and the CO
2
value can be changed with the aid of the Brink service tool, see §13.1.
