Abstract
An air control device includes a housing having an inlet and an outlet with fixed and movable plates extending across the inlet that both have indentically configured and spaced openings. The movable plate is moved by a room temperature-sensing device to control the amount of air flow. The outlet has a flow-directing vane for controlling the direction of air flow into a room.
