providing the thermal resistance required for continuous high-firing rate applications in hydronic heating systems
York S1-025-22273-001 Limit Switch 321894-708 Enhanced Safety: Integrated Energy CutThe York S1 025 22273 001 Limit Switch is a critical OEM safety component designed for precise thermal management within HVAC furnace systems. This SPST (Single Pole Single Throw) fixed temperature control operates on an auto reset logic, ensuring the burner circuit opens when temperatures reach the 150F trip point and automatically closes once the system cools to 110F. Engineered for York, Coleman, and Luxaire gas furnaces, this high limit switch
