Hunter SRC to Rachio 3 - Wiring

[s_ranga108]

Hi Thomas

Perhaps this is the solution

If you look at my photographs,

Wires Marked 1, 2 and 3 will have to go to S1, -24V and C. I just have to do a trial and error to determine what goes where

I wish my contractor had used colored wires. Would have made it much easier.

Need help wiring Rachio 3 from old Hunter system

@blakeyoung - my guess is the pink wire is going to the former rain sensor. I’d try the system with the pink wire disconnected and see if it still works. If the system still works, I’d leave the pink wire disconnected. The reason is that there is 24 VAC going somewhere - and if it was where the wire was cut in the yard, I’d hate for it to short against something and pull too much current through the Rachio and maybe burn out a component. Just my $0.02.
