The definition of a vav control box is a device that monitors, controls, and regulates airflow within a heating, ventilation, and air conditioning (HVAC) system. It is typically installed in a space such as a commercial or industrial building, and serves to maintain the desired temperature and air quality levels. The vav control box will monitor the temperature and air quality of the environment by measuring air pressure, air speed, and air temperature. It will then automatically adjust components such as dampers and fans, to ensure the desired temperature and air quality levels are maintained. The vav control box also features an adjustable temperature setpoint, and adjustable airflow settings, so that the user can customize the environment to their preference. Additionally, the vav control box will typically be connected to a Building Automation System (BAS) to provide automated, intelligent control of the HVAC system. Ultimately, the vav control box is a device that helps to maintain a comfortable environment, while keeping
