Summary: | The invention relates to an HVAC vent control system. There is a need for a mechanism by which an operator can easily adjust HVAC vent controls for vents remote from the operator. A roof panel forms a set of air vents and ports. A vent control unit includes left and right door units mounted for rotation on the panel. Each door unit has a louver door and a gear piece connected thereto. The louver doors are movable to control airflow through the ports. The gear pieces are in meshing engagement with the other so that the door units operate symmetrically with respect to each other. A control knob is coupled to the one of the gear pieces so that rotation of the knob causes rotation of the first and second gear pieces and corresponding movement of the left and right louver doors. |
