Abstract

A damper control arrangement wherein a damper blade opens and closes a flow-through orifice in response to selective moving means, the selective moving means moving the damper blade a preselected distance from the orifice opening to vary the opening of the orifice for a predetermined period of time prior to moving the damper blade to a fully open position. .
