SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

I have a Hunter ICC controller with 32 zones. Whenever there is power to the system, even if I have turned the system to "off", it will sprinkle its way through all 32 zones every day. Each zone sprinkles for a very short duration - nothing near the 20 - 30 minutes that are programmed for each zone - I haven't timed it - but maybe a minute or so. The programming is fine (one start time on the days it is supposed to sprinkle). I have even replaced the front panel and one module (which controls zones 1 - 8 which was determined (by the local distributor) to be bad . I have just replaced that first module again - 5 months later, under warranty, in case that helps (one valve ran whenever the system was on, we changed valves - then determined power was getting to it unless I flipped the circuit breaker to off.) My sprinkler man thought the transformer felt hot - and he thought that the voltage going into the system was too high? - he had me have the electrician check the incoming voltage - which the electrician stated was 124.5 volts - and he said was fine. The new module fixed the valve that was constantly running, but the momentary sprinkling of all valves continues... Does anyone have any ideas. I don't like my vegetation being sprinkled in the hot daytime sun. Thank you for any and all help.

I knew that was a possibility, so I had checked this and so did the distributor... So that is not the problem. Also, it does this "quick run through" sprinkling even when the system is turned to OFF. Circuit breaker must be switched off to stop this. Any other ideas? Thanks, again.

Yeah, when I got the new module yesterday, they informed me of the demise of the ICC. Back to the original problem - I think the controller is off when told to be off, since the scheduled waterings do not occur when I turn it to off - Just those darned "quick run through sprinklings" described. I know this situation sounds weird - the sprinkler man could not explain it - not the distributor - I'm just hoping someone here has some kind of explanation. Thanks again!

The controller is hard wired - so no washer plugged into same outlet. Tomorrow morning when it's light, I will go dismantle it all and see if that helps. I am aware of the test program, but am uncertain how it would begin on its own accord. I do understand this is strange - but I have been dealing with this for three years! Last year replaced the panel and the first module. First module again replaced two days ago. Will post what happens after I dismantle it. Of course, I will have to wait for the phantom quick sprinklings to occur. And I have to be watching out the window to catch it. So it may take me a couple of days.
Thanks to both of you who have posted.
