Question
I have a Rain Jet, RJC-66 controller on my lawn irrigation system. The display flashes '6A' then '6C' . What is the meaning of those codes?

Answer
Hey Bob, I'm not real familiar with Rain jet products because they are not considered a "professional" brand. I can tell you however, that if it is flashing 6A and 6C, it could be that you have time on zone #6 in both the A program and the C program. This controller does not display any kind of "codes". Good luck and have a great day.
