I just purchased a Rachio 3 and connected it 2 new water valve before setting up my irrigation system. I wanted to make sure the controller can operate the solenoid before actually installing it in the system.
I have prepared 2 new solenoid valves to connect to Rachio. The very first time I tired, Zone 1 worked. But then when I tried to see if the other valve could worked too, I got this red light. And after that, it never worked again. I always get the red light for both of the valves indicating that there is a zone fault. I can hear a sound and feel the movement from the solenoid but still I get the error message in the app saying there is a wiring issue. I have changed the solenoids to different zones and the result are all the same.
I do not have a master valve and I have turned that off in the app.
The controller firmware is up to date.
I live in Taiwan, the power voltage is 110 here. And I have a stranded cable instead of a solid cable for the solenoid.
Please let me know if anyone has run into the same issue and how can I fix this, thanks!
