I’ve had a Rachio 3 installed for two years and it has worked flawlessly. This weekend it was raining off and on but I wanted to check some nozzle alignment so I tried to do a quick run. I could not get any of my six zones to manually run? If the rachio was on the rain skip due to weather or a day that I had deactivated irrigation, would this prevent a quick run? Today I tried it again and was able to run zones manually? How can I test this to see if it’s operating correctly? What should I try if does this again ?
What should the voltage between “C” and the Zone feed on the control box?
Thanks!
