We had a guy come out and aerate our lawn.
I was gone, but my wife tells me that the guy must have turned on the sprinkler to test one area.
Well, hours later I get home, and it is still going.
My wife had gone to the panel and turned everything off, and even unplugged it.
I had to go out and turn off the water at the valve.
I don't think he did anything to the control panel.
Is there something someone can do outside that will turn on one zone, and not turn it off?
