Abstract
A motorized venetian blind system for covering a window of a space comprising a blind drive unit having two motors to provide for independent control of a position of a bottom rail and a tilt angle of a plurality of slats of the blind system. 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). The blind drive unit is operable to automatically adjust the position of the bottom rail and the tilt angle of the slats to limit a direct sunlight penetration distance in the space to a maximum direct sunlight penetration distance, and to maximum a reflected sunlight penetration distance on a ceiling of the space, while minimizing occupant distractions.
