Description
The Supco SHL501 Gas Furnace Limit Thermostat is a bimetal protection control part used to control a chamber temperature in gas furnace HVAC systems. It has a calibration to 170F and 40F, helping prevent overheating conditions in the heat exchanger and ductwork. It is installed in the chamber or the heat assembly sections. It operates as a high-limit switch that interrupts burner operation when excessive temperature is detected. It is used to ensure thermal regulation and consistent shutdown protection in systems.
