After a move back to sunny northern California, we have a rental with what may be the oldest controller that I’ve seen in years. I can’t find a model number, manual, or anything for it. The property owner has given us the OK to replace it with a Rachio 3. It seems to only have two working zones. We haven’t tested the controller itself because nobody knows how and randomly pushing buttons achieved nothing. The sprinkler valves are right out front and if we turn them on by hand, the sprinklers work.
Has anybody ever seen this controller before? The plan is to just replace it. Does the wiring look ok?
