Hi,
I am switching from Irritrol KD2 to Rachio 3 4zone controller. There are two zones currently on KD2 and two solenoids outside that are dedicated for front and back. On KD2, there are common wires going to one slot, two green wires and two red wires going into station slots. I did the exact same wiring on rachio but both zones turn on with zone 1 and zone two does not sprinkle any water. I also tried inserting common wires to two C slots on rachio but it is same result. Here is the KD2 wiring picture. Please suggest how should I wire rachio
Could you please post a picture of how you wired Rachio? And one of a solenoid and its wires?
Something is odd here, only one cable makes it to the valves, right? Where is the second going?
The wiring is simple, and should only need one cable.
At the controller:
COM - white wire
Zone 1 - green wire
Zone 2 - red wire
At the solenoids:
Solenoid zone 1 wired to white and green
Solenoid zone 2 wired to white and red
Polarity at solenoid does not matter, alternative current.
You should not need the second cable, but you need to figure out which of the two reaches the valves
