    If you want to set up the cut-out pressure on your pump control, while leaving the 'cut-in' down where it is, you'll also get a longer 'off' cycle, but if you set the cut-out pressure too high, the pump will just run forever since it can't reach that high pressure. This is easy to figure out since if you set it too high the pump will just keep running.
