Description
The York S1-02517620014 Pressure Control is a high-pressure sensing switch designed to monitor refrigerant line conditions and respond by opening or closing an electrical circuit at set thresholds of 380 PSI open and 300 PSI close. In HVAC systems used in chillers, rooftop units, and refrigeration equipment, it is installed on the high-pressure side to detect pressure rise and initiate protective system response. The control helps regulate operating conditions by signaling when pressure exceeds safe limits and restoring circuit continuity after pressure reduction. Its supports stable operation across load changes in cooling cycles.
