    • RB-122E, Electronic, 120V Low Water Cut-Off - (Water)

      Q:

      Looking at this to pair with a Peerless PF-110. The PF-110 has a built in service switch, so it seems that a separate shutoff switch is not needed. But the RB-122E schematic calls for it to be wired into an external switch. Is there a way to wire it on the PF-110, or does a separate power switch need to be added?
      Thanks!

        A:

        Doesn't the PF-110 have it's own sensor to detect a lack of supply water?
        The RB-122E is intended to be tied into the "Burner Shutoff switch" which
        is usually located outside the boiler room or at the top of the basement
        stairs when the oiler is in the basement. I might guess your PF-110 would
        still require a Burner Shutoff Switch beyond the unit's internal power
        switch.
        Good luck.

        A:

        The RB-122 is power by 120vac and the dry contacts get connected to the terminal board labeled for LWCO so if you take the source from the TB you have a switch controlling it from the equipment
