I replaced an old dial controller with a Gen 2 Rachio a few months ago. I verified all zones as running, but still needed to tweak advanced settings to get reasonable watering times.
Then… we had to dig a new electrical trench in the process. The machine severed the entire bundle of control wires as well as several pipes, a few of which were in the same area. We hired the original irrigation installer to make repairs, and he does not use Rachio.
The installer spliced wires and pipes, and left confident that the system was working.
Knowing that the zones would now be different, and given that I had not spent much time setting up zones, I reset the controller.
All seven zones are working. HOWEVER, I now have multiple zones running simultaneously.
My initial thought was that I have not properly identified the control wire. I’ve swapped that a few times, and the result was that no zones turn on. Alternatively, I guess it could be a problem with pipe splices.
Before paying the installer to return, I thought I would ask the community if this sounds like a piping issue or wiring issue. I appreciate any advice!
