Komfovent RH sensor + Belimo CO2 sensor in the extract air duct before the ventilation unit. It’s useful for not exceeding a certain CO2 threshold within the house.
Please note that you can have 1 or 2 RH sensors (extract, outdoor or both) or RH+AQ sensor. The firmware does not support two different types of AQ sensors, you must choose either CO2 or VOC.
