What Is the Ideal CO2 Setpoint for Demand Control ...

14/08/2019· The first option is more accurate, but the second is more affordable because there is no outdoor sensor. In both cases, CO2 levels are reduced well below the guideline values published by regulating bodies. When the CO2 accumulation difference exceeds 700 ppm, it means the ventilation system must increase the outdoor airflow (OA). There is an extra control requirement if the HVAC …
