SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

This helped me too, thanks a *ton*. By the way it's near the top of Google results for the 'PR OFF' error code on this line of models, so given their popularity w/builders it's probably helped a lot more people than us.

I had the same problem with the PR OFF error. I googled the problem and thankfully found this site. Even though the original post was from 2006, everything mentioned pertained to my problem today. I replaced the battery, fuses and it still didn't work. I read further and someone mentioned replacing the transformer (plug) and it immediately started to work. Once again, thank you for everyone's input
