Abstract
A control system for a top down/bottom up covering for an architectural opening includes a common drive shaft for raising and lowering a middle rail and a bottom rail between which a flexible shade material extends. A control element operates a spool lift system and a roller lift system, with the spool lift system being associated with the middle rail and the roller lift system being associated with the bottom rail. The lift systems are sequentially operated when the drive shaft is driven in either direction by the control element.
