John, the cut in pressure is often in the area of 80-90 PSI and the cut out pressure is usually in the 120 PSI range.

The system should have a PRV installed, which will open if the pressure switch fails on the cut out, and the pressure in the system continues to rise past the normal cut out pressure.

Look under the pressure switch cap for wiring information, or contact Speedaire for wiring details. Or, if someone out there can advise on wiring for John, please post.

Cheers,

Bill
