Description
The Johnson Controls P100AP-2 is a direct-mount encapsulated pressure control designed for reliable system protection in commercial and residential HVAC and refrigeration applications. With its open-construction design and automatic reset functionality, this SPST control provides dependable pressure-based switching to safeguard equipment from operating outside safe pressure ranges.
How It Works
The P100AP-2 operates on a pressure drop principle — the contacts open when system pressure falls to 35 PSIG and automatically close again once pressure recovers to 60 PSIG. This automatic reset feature eliminates the need for manual intervention after a pressure event, minimizing downtime and simplifying system maintenance.
