Looking to install my gen 2 I just got but wanted help confirming wires before I unhooked my old controller.
Any help is appreciated. Searched and didn’t find this specific example.
@Teekso - welcome to the Rahcio community.
- The white wire in the C terminal will go to any C terminal on the Rachio (2 on the 8 zone or 4 on the 16 zone version).
- The blue wire in the P terminal will go to the M/P terminal on the rachio. Be sure to configure the Master Valve/Pump Start Relay option in the application.
- The red wires in terminals 1 - 6 will go to the Rachio terminals 1 - 6.
- The yellow wires on the 24VAC terminal are not needed. Trace those wires back to a transformer that can be unplugged so there won’t be a vampire sucking electricity.
- Looks like there is a rain gauge (wireless?) with the two red wires on the 24VAC and the white and brown wire on the SEN(sor) terminals. Do you want to use a local rain sensor (not absolutely needed) in addition to the internet based weather station. If so, I’d need some more specifics to make sure we hook it up correctly - I think one red goes to SP, another red goes to SC along with the white and the brown goes into a S(ensor) port like S1.
