FIG. 1 is a perspective view from above of an irrigation controller showing our new design;
FIG. 2 is a top plan view thereof;
FIG. 3 is a front elevational side view thereof;
FIG. 4 is a right side elevational view thereof; the left side elevational side view is not shown, and is a mirror image of the right side elevational view; and,
