I have been having problems with the #1 slot on the controller. I have seen this particular problem 3 times Once on a repair, and twice on systems that i have installed. the system works fine when i go through the final walk through and adjustments, but a few weeks to a month later, the #1 station Quits working. the master valve doesn't come on with the #1 station, at first i thought just wireing problems, or cloged valves, but the #1 wire works on any of the other slots. Question: has anyone had this problem with this particular controller, or am I maybe wiring the system incorrectly?
