Abstract

A motorized venetian blind system (110) for covering a window of a space comprising a blind drive unit (118) having two motors (230, 240) to provide for independent control of a position of a bottom rail (116) via a lift cord (210) and a tilt angle of a plurality of slats (114) of the blind system. The blind drive unit has a headrail (114) with a side panel (216) and at least one of the motors is between between the side panel and the lift cord. The blind drive unit also has a spring-wrap brake. The blind drive unit is operable to adjust the position of the bottom rail to a preset position, and to adjust the tilt angle of the slats to a preset angle in response to receiving a single digital message (e.g., a preset command).
