I have a RAIN DIAL RD900 EX A which controls 6 stations. This has been working fine since I bought the house 6 years ago - until today. I have been testing individual stations over the weekend before switching to the automatic system today. Each station worked OK but when I switch to the automatic system, which switches in each station in series 1 through 6, station 2 remains open with each of the other stations. So that 1 comes on ( as well as 2) with reduced pressure even if I set station 2 with zero minutes run time. This is repeated if I try to run 3,4,5 or 6. I have removed the control box, reseated the battery and reset all the controls and conditions but same results. My next thought is to change the battery but that seems a faint hope. Any ideas?
