What happens if you have a pressuretrol with the " diff " setting higher than the main setting , and the diff is subtractive ?

    Haven't tried this

    but I'd think it would shut off on pressure, and not turn back on when the pressure drops.

    Gonna have to try it

    next time I go back to do a skim and purge on a system . My guess is it would cut back in at 0 psi , but that;s just a guess ..............
