How do I get the well pump to cut in at 40 PSI instead of 25 PSI? Turn clockwise to increase pressure, counterclockwise to decrease. Apparently, there is no way to adjust only the cut in pressure? The intersection at point B lies outside . Normally Closed (NC) switches break the circuit when the pressure crosses the upper limit. The article above explains how to make pressure control switch adjustments more completely and accurately than if I try to make it up again here. c.
