I have the Gen 1 for over five years now and it works great. A couple of weeks back when I was out of town, the sprinklers came on and remained on till I got called about street flooding. The controller had gone offline right after Zone 1 started, and stayed on for 6 hours till I had a neighbor go in and reset the controller - which resulted in the sprinkler going off. This is worrisome since I thought the program was run correctly even when the controller was offline. This morning I once again see that the controller was offline but it was after the cycle so no flooding this time. Any suggestions?
