Odd or Even day watering schedules are available on all Hunter controllers. This feature allows you to schedule your irrigation to occur on odd or even days of the month.

All Hunter controllers will also allow you to program non-water days. For example, if you mow the lawn on Saturday morning, you may not want the irrigation to come on that day. You can select even watering and Saturday as a non-water day. This way, the controller will water every even day but never on Saturday.
