Orbit 3-Outlet Digital Hose End Timer

If you want the truly automated experience, a digital timer like the C013 is just what you need. With three built-in outlets, this timer will let you run three totally separate zones on different schedules without needing two separate timers! This item connects easily to a garden hose or spigot and sports hose thread ends, making it compatible with other basic system components like the A015 backflow preventer, F300 filter, PR204 pressure regulator, and LF003 swivel adapter.  Note that you will need a head assembly on each outlet for proper system operation.

This timer runs off of two AA batteries that last up to one year before needing to be replaced, and features two discrete programmable ports and an LCD screen. There's even a video explaining how the controller works and how to program it in plain English!
