Question
I have a Toro Greenkeeper 212 timer due to watering restrictions I can only water 3 days a week so I was starting the sprinklers manually ( instead of resetting the timer ) now they will not start at all I checked the fuse and it looks good I turned the timer from rain delay to run and they ran ok so I turned them off to wait for the next watering day but they restarted the next day even though the timer was in the off position I had to unplug the unit to get them to stop any ideas thanks

Answer
Hey Greg, what is happening, is that the switch is not making proper contact anymore, and the controller does not recognize that the switch is in the off position. Probably time for a new controller. Let me know if you have anymore questions, thanks and have a great day.
