Carrier spec for the 24ACC636 is around 590 PSI if I remember right. If it’s tripping at 445 the switch is definitely faulty or has drifted way off spec.

Supply water jumps, zones overreact, then everything calms down again.
Rotation works on paper, but the transition itself feels rougher than it should be.
