With the Zehnder CO2 sensor, your ventilation system can operate demand-controlled ventilation. The sensor continuously measures the CO2 levels in the air, allowing for additional ventilation when needed. This ensures a healthy air quality in your home! The system connects via a wireless RF connection. This version is suitable for built-in installation and comes with a Zehnder cover frame. The Zehnder CO₂ control sensor wirelessly pairs with the unit but always requires a 230V power supply to function.
