Direct Compatibility: Engineered as a drop-in replacement for PCBFM131S and PCBFM103
mounting with the coil upright is recommended to prevent sediment buildup in the pilot orifice
Precise Sensing: High-accuracy NTC thermistor assembly ensures the controller accurately tracks boiler temperature for safety limit and circulator control
indicating whether the supply or branch line is active or inactive based on pressure thresholds
York 024-39397-001 Flow Switch 30067439-890 Direct Compatibility: Engineered as aThe York 024 39397 001 Flow Switch is a mission critical differential water pressure (DWP) control designed for high performance HVAC and chiller systems. Engineered as a 24V flow switch, this component monitors real time fluid movement to protect downstream equipment from dry run conditions, pump cavitation, and thermal overload. Rated for a 150# DWP (150 PSI) maximum operating pressure, it provides the robust durability required for industrial and
