SC-- SPRINKLER CHALLENGED

We put in a sprinkler system last year for the yard--and mostly my garden. GREAT help with the watering chore. I HATE to admit it, but I seem to be Sprinkler Challenged when it comes to setting the automatic timer. It's supposed to be SO easy.....but I am about to throw in the towel! For some strange reason I have the days down and the time the system is on correct, BUT the system goes off MULTIPLE times on the nights it is programmed to water. I am a HIGH MAINTENANCE sleeper.....thus EACH AND EVERY time it cuts on it wakes me up....and I don't easily go back to sleep. Thankfully it is only 3 nights a week....but ironically it is the same nights that I don't have to get up at 4:45.....so ANOTHER interrupted night of sleep. ARRRRRRRGGGGGHHHHHH as Charlie Brown so well said!
