How to Program a Dual Star and Dual Program Sprinkler Timer

Replace the batteries with fresh batteries for best results. Dual Star timers take 9-volt batteries or AA batteries. Hit the “reset” button on the back of the timer after installing new batteries.

Set "Program A" first. Move the dial to the time and date section. Set the correct time, date and year on the digital face of the timer by pressing the buttons on the side.

Turn the dial to the start time section. This procedure is the same for sprinklers or regular timers. Set the desired start times with the buttons. Turn the dial to the appropriate sections on the dial and set the duration of time you want the lights or sprinklers on and the desired days for the timer to come on.

Push the button for "Program B." Turn the dial to the "interval" setting. Choose the desired watering interval for program B. This program will follow all of the directions of the initial settings. Push the "Start" or "Enter" button to save the data.

Turn the dial so that the “Auto” or “Start” label on the dial faces up. Repeat these instructions every time you want to change the starting times, days or duration that you want the timer to be activated.
