Whether you choose wall-mounted room sensors or duct sensors and connect them to a ventilation unit or window opening system, you can start ventilating efficiently right away. The unit will simply start only when the air is really dirty. This means you don’t waste money on energy costs.
The choice of sensor depends on what is the primary source of indoor pollution. As a primary indicator, if human pollution is prevalent, carbon dioxide concentration is the most effective pollution indicator.
Another major pollutant is so-called volatile organic compounds, which are exhaled from furniture, carpets, paints, cleaning products or even cooking and frying. Where CO2 concentrations can be low, VOCs can be high.
As already mentioned in the first point, the unit switches on and off, or influences the ventilation intensity, thanks to sensors completely independently. You don’t have to think about when to turn the unit on and off, when to increase or decrease the power, or the exact on/off time.
