Hello. I’m installing the Rachio 3. I’m OK with the single wires that go to Zones 1-5. However, I’m unclear about the Sen, C & P wires shown on photo from Hunter X-Core (the timer I’m replacing). It appears the master valve wires are brown in color. Looks like one is attached to to P and one to SEN, on the Hunter. However on the Rachio I only see a single M terminal for the Master. Humm…
Thanks in advance for guidance.
C is common, and will go to one of the C terminals on Rachio.
P is pump (or master valve), and will go to the M terminal. Make sure during set up you tell Rachio you have a master valve/pump.
Sensor wires, one wire will go to S1 terminal, the other will go to -24vac terminal.
Zones will go to their corresponding zone number.
Disregard the two yellow wires on the left, that is what powers the Xcore. Rachio uses the barrel plug.
