My unit continues to run, going thru all zones and then start over again with zone 1. I have not been able to stop it.
Do the lights on the controller show it running the zones? If you remove power from the controller, do the zones stop running? When you plug the controller back in, does it boot up ok? Do the zones start running again?
Do you have any automation platform set up that may be causing the runs?
What schedules do you have enabled?
