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
-
First two brown wires - ignore, replaced by the Rachio power supply jack.
-
Red, Blue, Green and Yellow go to Rachio 1, 2, 3 and 4 terminals - these are the zone wires.
-
White goes to Rachio C - this is the valve common.
