This switching relay features a 30A resistive load rating at 60Hz

this kit is designed for 120V solenoid assemblies

Can I mount this horizontally if my thermostat is vertical

or the control board flashing a code for "low flame signal" despite a visible burner flame

whereas a safety valve is typically a "pop-action" device used for compressible fluids like steam or air

York S1-025-22273-003 Limit Switch This switching relay features aThe York S1 025 22273 003 Limit Switch is a critical OEM safety component engineered for precise thermal monitoring in high performance HVAC systems. This SPST automatic reset limit switch is calibrated to open the electrical circuit at 160F, effectively halting operation to prevent heat exchanger damage or unsafe conditions. Once the induction or blower housing temperature stabilizes and drops to the 120F close setpoint, the switch automatically
