Migrating from 446PRI Contoller

Hi…after ~30 years the old 446PRI Contoller finally died and I am moving to Rachio. Unfortunately the wiring is beyond me and having read on this support page a little more complex than expected. Would anyone be able to take a moment and help me map the existing wiring to the new Rachio? For reference, I’ve uploaded pictures here. Thank you very much!

@Sparro - simple

  1. First two brown wires - ignore, replaced by the Rachio power supply jack.

  2. Red, Blue, Green and Yellow go to Rachio 1, 2, 3 and 4 terminals - these are the zone wires.

  3. White goes to Rachio C - this is the valve common.


Thank you. Got it all done in minutes. Really helpful!
