Background: I draw water from a lake for my sprinkler system. The system works great except Zone 9 is always on when the system is running.
What ever time is set for Zone 1-8 is the same amount of time Zone 9 is on.
When Zone 9 runs BY ITSELF it runs for the amount of time programmed into the controller.
I can provide a digital picture, controller brand and model number this afternoon, or any other information you may need to help me solve this problem.
Of course I would like to STOP Zone 9 from running when Zone 1-8 is running. Diverts water and water pressure!
Perhaps zone 9 is a master valve?
