Last year my system (9 station system) started going crazy. It was set to come on at 5 am each day and each station had a specific time to run through 8 stations. It would shut off until the next morning. Out of the blue it started coming on but instead of each individual station coming on one at a time more than one stations would come on which means that area of lawn would not have sufficient pressure to reach that area because too many heads were on. We shut everything off, reprogrammed and it is still doing it. If I hit manual button the system will come on correctly starting with station 1 and go through the program correctly. This is bad for me because now we cannot leave the property when it is hot because the system wont come on by itself. HELP!
