York S1-024-34769-000 Pressure Switch Els PW 17895 By providing high-accuracy air velocity

By providing high-accuracy air velocity measurement

maintaining original factory safety standards

It will open the circuit when the pressure reaches 600 PSI and will automatically close the circuit once the system pressure drops back down to 475 PSI

Once the system cools to the 210°F reset point

allowing it to interface with a wide range of DDC controllers

York S1-024-34769-000 Pressure Switch Els PW 17895 By providing high-accuracy air velocityThe York S1 024 34769 000 Pressure Switch is a high precision safety sensor specifically calibrated for York, Coleman, and Luxaire gas furnaces. This Normally Open (N O) differential switch monitors the vacuum created by the draft inducer motor to ensure proper combustion air flow before allowing ignition. With a factory calibrated 1. 60" WC set point and a 0. 4" WC reset, this component prevents the unit from operating under hazardous venting
