  • Method and system for identifying indoor air quality (IAQ) monitor installation location
    Patent number: 12104813
    Abstract: A method of monitoring a heating, ventilation, and air conditioning (HVAC) system to detect installation location of at least one indoor air quality (IAQ) monitor. The method includes monitoring, by a controller, operation of the HVAC system, determining, by the controller, whether power exists at a duct terminal of the at least one IAQ monitor and responsive to a determination that the power exists at the duct terminal of the at least one IAQ monitor, configuring, the at least one IAQ monitor as being installed within a ductwork.
