5 wires 6 zones on previous controller

Troubleshooting Wiring

Hi, I’m trying to figure out how to wire my Rachio 3. On my previous controller there were only 5 wires but 6 zones. Not sure how to transfer this over. I’ve attached a picture of the previous wiring

@jermz - It looks like only 5 zones were in use as there is not a wire connected to zone 3. There are wire doubler devices that can split a zone off an existing wire due to a wiring break. Does any water come out of a sprinkler when zone 3 is run when sequentially stepping through all the zones?

Move the white wires to the Rachio C terminals and the zone wires to the corresponding Rachio terminal. Ignore the 24 VAC Power line and the loopback connector on the yellow terminal (probably rain sensor).

Hmm, you’re right, never paid attention, zone 3 doesn’t turn on during the cycle.

Thanks!
