You set up the watering zones by plugging the hand-held controller into the watering head. Then, using the keys on the controller, you give the zone a name, like "ROSES" or "FRONT LAWN". Using the arrow keys, you direct a stream of water around the outline of the zone you want to water. Set points around the zone by pressing a key on the controller. The watering head remembers the points (called "Dots") that define the zone.

You can use from 3 to 24 dots to define a zone of almost any shape. The zone can be any size up to the range of the watering head, which is a 60-foot (18 m) diameter circle.
