A timing device for operating a valve assembly at a predetermined time on a given day or days. The device includes a timer dial and a pinion driven by separate gear trains from the same motor and constantly in operation. A valve assembly drive gear is connected to the pinion and rotated by it at said time through an actuator arm manipulated by the timer dial. The timer dial in addition includes means associated therewith to independently manipulate a selected portion of the valve assembly at a predetermined time on a given day or days.
