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 different ways, namely based on CO
2
measurements or
based on a time program. Two different 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.
