York S1-025-33335-000 Control 320074-702 flame rectification sensingMaintain precise refrigerant regulation in low ambient conditions with the York S1 025 33335 000 Head Pressure Control. Specifically engineered to manage condensing pressure, this HVAC head pressure switch functions within a pre set operating range of 170 to 230 PSIG. By cycling the condenser fan or modulating flow, it prevents the system from operating below critical thresholds during outdoor temperature drops, which ensures a consistent refrigerant
