Got a call today that two controllers at a site had fired last night when both were on "rain off" and have been since last Wednesday. I've never seen one controller do this let alone two. I made the remark that if two controllers fired while off then I'm buying a Lotto ticket because the chances of winning are greater than this happening. I have noted heavy dew lately with gopher mounds and other dirt areas showing moisture in the morning. Heck... happened to me last Friday morning. Went out to continue a project and at first glance looked like someone had turned the backflow on and fired the sprinklers.
