Zone issues
Hi Folks,
Need some troubleshooting help.
This is a three zone system, and it is operated manually from the controller and has been for years. Zone one is started and it then cycles through zones 1-3.
New problem at start up this spring.
When zone two is supposed to start, it wont, but zone three does (and controller indicates zone two). When zone three is supposed to start, it does (and controller indicates zone 3.)
All three zones can be manually started in the valve box. There have been no wiring changes and connections are clean and tight in the box and the controller.
Any ideas?
Thanks!
