    Jandy system coming on by itself (update)

    Ok, so this has been going on for a few months.

    My pool or spa will randomly come on.....usually once every week or two.

    So I did some googling, and it sounded like my main board is going out. So I bought the latest iAqualink RS upgrade kit and installed it last Sunday. Great, problem solved.

    Or so I thought......the pool came on this morning by itself.....and then the spa came on by itself this afternoon.

    Argh!!!

    I'm baffled......these are the only things I can come up with:

    1) Random relay activations (doesn't really make sense....especially in "Spa" mode, since that requires Jandy auto valve switching also).
    2) Neighbor with competing PDA system. (I'm still using my old PDA/radio also, as an on/off). I walked around my neighbors with my PDA and it didn't pick anything up.....but that may not mean much. I may just unplug my PDA radio and be done with the PDA. At least I remove a potential source.
    3) Other random radio signals (doesn't really make sense, since it is not just a simple signal, but perhaps.....)
    4) Main power spike (wouldn't make sense, unless jandy has a really really bad circuit board design across many years)

    That's all I can come up with. Since I replaced the main board, it can't be that. PDA interference seems to be the only plausible idea.

    Any other ideas?

    Mike

    Update: I disconnected the PDA radio from the control board....all quiet so far.

    Do you have a wired spa side remote?
