sensor(s) on and off , select the right setting at step number 6.1 in the
settings menu ; in order to set the minimum and maximum PPM value of the CO
2

11.5 Demand-driven ventilation 2.0
Demand-driven ventilation allows the ventilation need to be matched to the air quality. Matching the ventilation need
with demand-driven ventilation can be done in two diff erent ways, namely based on CO
2
measurements or based
on a time program. Two diff erent sets are available for this.
Manual operation with the aid of an extra connected multiple switch of course remains a possibility as well.
For further information regarding setting, operating and connecting demand-driven ventilation 2.0, refer to the
installation instructions supplied with the demand-driven device.
