It operates through a temperature-sensing element that opens or closes an electrical circuit when preset limits are reached. Mounted on heat exchangers or air handling units, it connects to control wiring inside furnaces, rooftop units, and ventilation assemblies in HVAC systems. It maintains stable cycling and supports equipment by reducing thermal load during continuous operation. It is used to ensure dependable shutdown response and consistent temperature protection in operating conditions.
