Wiring Your Rachio 3 Controller

Last Update:Feb 18 2022 6:47pm


Summary

Now that you have your Rachio 3, let's wire it up. The terminals at the wiring bay can be compressed with just a fingertip, you can easily do it yourself! You can refer to a picture of your previous install to help you make sure that everything is at the right spot.




The wiring bay of the Rachio 3 includes terminals to house the common wire, wires for each zone, and advanced wiring components. It is one long, color-coded strip for easy wire and zone identification. Also, easy-press connectors in the wiring bay can be compressed with just a fingertip.

Rachio 3 has bigger wiring terminals to accommodate a wider range of wire gauges (14-22 AWG).



Features:

  • C - Common wires;
  • Zone wires (1-8 and 9-16);
  • M - Master Valve or Pump Relay wiring;
  • S1 Sensor 1 & S2 Sensor 2 (Rain or Flow);
  • 24 VAC+/-. The 24 VAC + and - terminals are used for extra wires from wireless sensors. These terminals replace and perform the same function as the SP and SC terminals from Generation 2.
