It looks like you have a rain sensor and no master valve. It is hard to tell on some of this, but it seems like the following based upon your picture and LIT-185RevE (hunterindustries.com):
- The black wires going to 24 VAC are the power supply wires (input) and should not be hooked up to the Rachio. Instead, you should use the Rachio supplied power supply.
- The red, white, & blue wires to power and ‘R’ are for a remote controller, which would not be used with the Rachio as its remote is an app on your phone.
- You already know the zones’ red wires.
- The tricky one might end of being the white wires to ‘RS’ and ‘C’. The ‘C’ and one of the ‘RS’ wires are for a rain/weather sensor. The other ‘RS’ wire is a common for the valves. If you can tell which one, that should be hooked to ‘C’ on Rachio. If you cannot, you should be able to tell with trial & error or else with a multimeter if you have one. We can help you as needed there. I personally would not suggest hooking up the rain/weather sensor at this time. It gets hooked up differently on the Rachio and with the localize weather, you might not need that. Please let us know your thoughts.
