Its safeguard feature automatically shuts water off when the battery is low, and the Rain Delay feature pauses watering schedules to prevent unnecessary watering. Two AA batteries not included. Two year warranty from the manufacturer Gilmour. The Dual Outlet Electronic Water Timer is a great tool for reducing the amount of time spent irrigating, and it reduces water waste by delivering water where and when it is needed in just the right amounts.
