ICC weirdness - ideas?

    I had just finished a repair job and as I was walking across the lawn to my truck, zone 7 popped up and sprayed me for like 2 seconds. I stopped and turned around thinking the customer was messing with me, but no. After a couple of minutes #7 popped up again for a couple seconds and shut down.

    I walked over to the clock (Hunter ICC) and everything looked fine. Time of day, start times, ohms at 22 and voltage at the transformer is 28.9. I manually turned 7 on and off a couple times, worked fine.

    I shut the water off and pull the solenoid thinking. "Hey maybe there is some trash under the plunger". While the solenoid is in my hand it buzzes for a couple seconds and stops. Now I know it's the clock, but what the heck?

    Anyone see this before? I haven't.

    You probably need to bleed the blinker fluid lines; got air in 'em!

    I have no idea. Had a similar thing happen two years ago with two WM1800's SL. After speaking to tech support it was concluded that it was the internal clock malfunctioning. Kept the time, date, and programming correctly.
     
  5. I'd swap the plate out.
    Having said that at a wire trblshtng class the instructor told a story of a phantom short burst turn on. By sheer accident they discovered it was happening when they used the office phone. turned out the phone company had damaged the wires a little and they were drawing current somehow from the phone line. If I see the guy at the IA show I'll get him to repeat it to get better details.

    You either have a bad face plate or a module shorting out - I've seen it several times before.

    Either can be caused by insect damage (in my case fire ants nesting in the cabinet), a power surge from a malfunctioning gfi circuit or in one case a homeowner who had a stuck valve and tried closing the circuit breaker when the controller was incorrectly programmed. When that didn't do it (closed the wrong breaker)he pulled the ribbon strip out of the face plate - instead of just turning the selector to off. Well it closed the valve but when he saw some dry grass later in the week he plugged the strip back in and shorted across the module which had the section that was programmed to run as well as screwing up the face plate.

    Kill the power to the controller, pull the modules and look for signs of a short - if that isn't it than the face plate has crapped out.

    You can try a hard reset of the face plate first although I think the damage has already occurred.

    I've had several metal cabinet icc's do this. I changed everything out on them.

    Maybe on some products but the PGP is only two years. :hammerhead:

    I think the ICC is five.

    Replace the friggin controller with a Rainbird ESM... Never did like Hunter controllers.
