Question

Good Day, I hope you can assist me. I just moved into my house and for some strange reason we are having issues setting the timer to come on and go off on the outside of the house. One day we came home and it was on that means it was on all day. We have the one with the green and red sticks. Not sure how to set it. Please assist. Thanks, Ty Parris
