I've done more research one my problem. It looks like a valve controlling on of my six zones won't close. It stay's open spraying water. I can manually advance thru the other zones, but this one will continue to stay open. I don't believe it's the controler. I've reset my controller. I've even disconnected the wire at the controller for the bad zone and the water still sprays. This makes me think it's mechanical in the valve; not electrical in the controller? Do I unscrew the value head and see if there is a damaged diaphragm? Maybe freeze damage from not being winterized properly? Any ideas? thanks,
