The York International S1-025-29041-002 Auto Limit Switch 120-150°F controls temperature-based operation within the heating system by monitoring heat levels and switching the circuit when the set temperature set point is reached. It responds to temperature changes through its internal sensing process to control electrical flow between connected sections. It's placed inside the heating system near the airflow or heat exchange area & the switch connects with wiring terminals for signal transfer. Its optimum configuration allows for temperature control, maintains proper system response, and ensures the heating equipment operates smoothly during regular heating.
