Does anyone with an AQI sensor in their house actually use it to control HVAC equipment, or is it just for monitoring? In a commercial HVAC control system, if the AQI sensor (or CO2/NO2) reaches [setpoint], a make-up air unit and exhaust fan (or similar setup, could be an exhaust fan and outside air damper) will turn on until the AQI value is below the setpoint. Is anyone using an AQI sensor to energize a relay coil to turn on their furnace fan to try and correct PM2.5 and CO2 levels?
In Korea, they sell complete systems that do this. Basically sensor and HVAC and/or kitchen stove fan. These systems are built in high-end new apartments.
