  • Pressuretrol Wiring Question

    In my steam system, the pressuretrol relay is wired to interrupt power to a single zone switching relay (Taco SR501) that supplies power to a thermostat and controls the oil burner. Whenever the pressuretrol trips, the thermostat looses power. My proposed solution to keep the thermostat powered at all times is to rewire the pressuretrol relay in series with the thermostat, and to permanently wire AC power to the Taco relay board. This way, the pressuretrol can still override the thermostat without interrupting the power to it.

    Any problems with my solution?

    Thanks,
