We just moved into our new home in Arizona this year and we have no idea how to change the timer on our sprinkler system. The other people who lived here had a landscape company come in and do everything to the yard and he said he had no idea how to do it. I am attaching a picture hoping someone can help me. My trees and plants are turning brown, my sprinkler system is only coming on once a day. Someone please help!!! I do not want to call a landscaper out to show me how to change the timer on this system. Thank you!!!!
