    Wiring so SWG is powered only when the pump is on?

    What is the advantage of wiring the Autopilot so that the SWG is powered only when the pump is on?

    If the SWG runs while the pump is off hydrogen gas will accumulate and could possibly explode. The flow switch should prevent this from happening, but flow switches are not all that reliable, so it is nice to be completely sure by powering down the SWG while the pump is off.

    Agreed. I noticed that our's was not turning of when the pump was off (not too big a deal since we run the pump on low 24 hrs per day). I did want it corrected and the PB sent the electrician back over to twist a few things together in the panel.
