    if you disconnect the only common from the controller and the zone still runs
    automatically,
    one of my service guys has a total control controller at a commercial site. he had a ticket saying the rain sensor was not working. after getting in to it he pulled the common out while the zone was running and it still runs until he cuts it off with the dial.

    best i could tell him was common maybe skimmed somewhere helping it ground out since the solenoid is in, it does not take much to hold it in?
    i will keep ya'll updated*trucewhiteflag*

    I don't think a AC system like our timers would work with just a earth ground.

    I could be wrong. I would venture that the timer as a internal short before thinking that the valve was grounding to earth and still running.

    I break the common in the valve box or in the timer.
