New User, Wiring assistance Needed


Hello all. Glad to be a part of the awesome community. Looking forward to getting my system working. I’m replacing my Hunter XCore system with a Rachio Gen 2 system. My system was working great before installation but we wanted to upgrade to Rachio. I took pictures of my setup prior to attempting setup but have yet to find explanations for every wire that was used in my system.

In any case I tried to run my zones after install and nothing happens. It tells me my zone Is running but no sprinklers turn on. HELP!


Seems to me that you have a master valve/ pump. Make sure to connect blue wire to the M terminal and enable master valve or pump (depending on what you have) in the software.

You also seem to have a rain sensor on the red / black wire pair. You’ve got the red cable in the right place, but installed the white wire instead of the black. Remember to turn on the rain sensor within software on S1 input.

The second white wire should be connected to an available C terminal.

Help move from Hunter X-Core to Rachio 2nd Gen

@Gene thanks for the reply. Shortly after posting I realized the mistake with the Blue P wire and the system kicked on. I have it set as master but not sure if I need to set it as Pump just because it was a P wire. Especially since the rest of the system was wired so weird.
The rain sensor wiring was throwing me for a loop. So the red and black wires that were connected to the SEN terminals should connected where? And you say I should take the white currently in the SC and move it to a C terminal?
