Zone w/mind of its own

We started our system up for the season, when we turned the water on to the system, one of the zone’s immediately started running. I was able to cycle through all the zones, however, that one particular zone continued to run as well. That only way to turn that zone off is to shut the water off to the system. Any thoughts?


You will need to take a look at the control valve for that zone.
