Thermostats connect to the HVAC system and control its functions to maintain a specific temperature or temperature range in a space or process system. Room thermostats regulate the HVAC system to maintain a desired temperature in residential and commercial applications. They sense the air temperature and switch the heating or cooling system on or off as the temperature varies. Process thermostats monitor and regulate the temperatures of air, liquids, or gases in manufacturing, commercial food service, or industrial processes. They provide precise control to ensure equipment and production run smoothly. Building automation thermostats allow for remote monitoring and temperature control by communicating with building automation systems and sensors and regulating the HVAC infrastructure.
