When the system detects a \u003cstrong\u003efall in pressure to -0.45\" WC\u003c\/strong\u003e, the switch closes, completing the circuit. This functionality is critical for monitoring and protecting HVAC equipment from operating outside of safe pressure parameters.\u003c\/p\u003e\n\n\u003ch3\u003eApplication\u003c\/h3\u003e\n\u003cp\u003eThis component is an \u003cstrong\u003eOEM York replacement part\u003c\/strong\u003e intended for use in compatible York heating and cooling systems.
