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

Hi, I am hoping someone here can assist me. I moved into a house that has an Irritrol Total Control sprinkler system already in place. Unfortunately, the previous owner didn't leave the manual.

Still, I was able to use it every other day on the "manual program" setting in which it will turn on each of the 6 zones for a specified number of minutes in sequence. I was content with that since i am lost when it comes to this sort of stuff. However, my young son got into the controller (which is mounted outside) while I was putting something away and now it won't even do that. There is also a new message on the display that wasn't there before: "<i>master valve</i>." Most perplexing is that it has 4 different programs A through D. I stuck to "Program A" when turning on the sprinkler manually (and sequentially). I never dealt with the other programs. The setting was on Program D when i discovered my son mauling it. Now, when i try to turn it on as usual, instead of starting up when i turn the dial to "Run", it merely flashes "A" and "D" at me as if I were never pressing the "ON" button to begin the manual sequence.

I do hope this makes sense and someone can help me. Here is a link to what the controller looks like:

thanks.

ps- did I mention that the sprinkler now turns on at odd times more than once a day (!) and I cannot figure out how to stop it? Please save my pocketbook.
