Application
This limit switch is a direct OEM replacement for Sterling HVAC heating systems. It is used to monitor heat exchanger and air plenum temperatures, cutting power to the burner or heating element if temperatures rise beyond the designed operating range. The auto-reset function restores normal operation once the unit cools down, making it ideal for commercial and industrial heating applications where continuous uptime is critical.
