Hello! Brand New to the Rachio family and very excited about it!
I moved down to Florida from Ohio where we didn’t need to worry about sprinklers. My wife and I bought a house from 1980 and it appears our house has the same controller since the house was built or close to it.
Looking at our current Rain Bird EZ-1D we have 4 black wires, a yellow, red, blue, and white wire. I’m guessing the black are our zones which I’ll need to label. I believe the yellow is our Common wire. If that’s accurate I’m not sure what to do with our red and blue “hot” wire or the white.
Any assistance would be greatly appreciated! Let me know if you need more pictures. Thanks!
