When you connect your product for the first time, the CO2 sensor will use the first 14 days (or less) of operation to calibrate itself to local background levels. You should not be concerned if readings on the sensors appear unusually high or low, or if a lack of agreement between sensors is found.
Using CO2 sensors in HVAC (heating, ventilation, and air conditioning) systems ensures that optimal levels of indoor air quality are achieved. Furthermore, by facilitating DCV (demandcontrolled ventilation), carbon dioxide sensors lead to an increase in the energy efficiency of HVAC systems as well as significant savings on energy bills.
CO2 Sensor becomes more accurate. When you connect your product for the first time, the CO2 sensor will use the first 14 days (or less) of operation to calibrate itself to local background levels. You should not be concerned if readings on the sensors appear unusually high or low, or if a lack of agreement between sensors is found.
