The new Zehnder CO2 sensor based on the latest technology, assures optimal accuracy and ventilation control, packed into a well-designed and user-friendly device. It responds to the highest demand control ventilation standards according to the Energy Performance of Buildings Directive (EPBD) from the EU. Using the new Zehnder CO2 sensor with Zehnder Comfortable ventilation systems leads to peace of mind thanks to well-being conditions and high indoor air quality through demand controlled ventilation. With its 2 different functions, the new CO2 sensor from Zehnder meets all requirements: As an installer, you can opt for the controller mode, that means the sensor controls and indicates the necessary air volume to the ventilation unit. Or you can select the sensor mode, whereas the ventilation unit automatically determines the optimal air flow based on the CO2 measurement from the sensor. Either way, you are always on the safe side as no mistakes are possible: the sensor is easy to adjust with limited options – and typically even runs fully automatically, unless temporary manual operation is desired. Easy to understand and to operate: the single button operation avoids confusion and allows to select automatic ventilation, as well as three increments of ventilation speeds on sensors that are in in control mode. High CO2 warnings are only given in case that the CO2 level is too high while increased ventilation cannot reduce it quickly enough. The 0-10 V version will be powered by the ventilation unit or the option box.
