Question
Jim,

Sometimes my zones will come on at the same time?
1 is set for off
2 is set for 10 min

howver, 1 and 2 are coming on at the same time.
Even if I run 2 on manual 1 goes on.

nothing has been changed at the box just turn certain ones off periodically by the timer.

somtimes it is a different zone that follows another like 9 and 10 at the same time.  

Answer
Hey Sean, I hope this helps. It sounds like one of two things, both having to do with the electrical side of things. Sometimes as the controller gets old, the terminal strip where the wires hook up, start to corrode, and the contacts touch each other. The other thing that it could be, is the field wires might be corroding out, and touching each other. The first thing to do, is un-hook the wire in the back of the controller marked #1 (field wire to zone/valve #1). Now turn on zone #2, and see if just zone #2 goes on. If just zone #2 goes on, then the short is in the controller, and it probably needs replaced. If both zones are still going on, (with the #1 zone wire un-hooked) then the short is somewhere between the controller, and your valves. You would need to either follow the wires to find the short, or replace the wires. Let me know if I can be of anymore help, thanks and have a great day.
