How It Works
This limit switch monitors supply air or heat exchanger temperatures within the HVAC system. When temperatures rise to the 125°F fixed open threshold, the SPST normally closed contacts open, interrupting the circuit to protect the equipment from overheating. Once temperatures drop back to 115°F, the auto-reset function automatically closes the contacts and restores normal system operation — no manual intervention required.
