hardie RD 900 irrigation system


Question
I disconnected my sprinkler system to hang some peg board in my garage and lost to rewiring diagram I had made.  Could you e-mail me the color coded wiring diagram please?

Answer
Hey Louis, I hope this helps. Depending on the installer, there is no set way that every controller gets wired. What I would suggest, is first go out to your valves, and see what colored wire all the valves are hooked to, this would be considered your common wire. On the controller, this terminal will be marked with a C (common). Then once you have figured your common wire out, then turn on a station/valve manually, lets say station #1, and touch another wire (a hot field wire to the different valves) and you can determine what valve comes on. By touching the different wires one at a time to terminal #1, while the station is running, each valve should turn on one at a time, and then you can determine what sequence you want the valves to run. Just hook the hot wire to the terminal # you want it to be. Let me know if I can be of anymore help, thanks and have a great day.
