When I first installed the Yardian, I had just almost completed installing my sprinkler system and tested it with all three zones. It worked fine. Had to do some finishing touches and now it will not find the valves on scanning. I checked all of the wiring and everything is good. How do I receive a replacement for my defective controller?
