Patent ID: 8508169

Claim:
A method of automatically controlling a position of a motorized window treatment while minimizing occupant distractions, the motorized window treatment adapted to control the amount of sunlight entering a space of a building through a window located in a façade of the building to control a sunlight penetration distance in the space, the method comprising: building a timeclock schedule having a start time and an end time, the timeclock schedule including at least first and second consecutive timeclock events having respective first and second event times spaced apart by at least a desired minimum time period that may occur between any two consecutive timeclock events; calculating optimal positions of the motorized window treatment at a plurality of different times between the start time and the end time that will ensure that the sunlight penetration distance will not exceed a desired maximum sunlight penetration distance at the plurality of different times between the start time and the end time; using the optimal positions to determine, for the first timeclock event, a first event position to which the motorized window treatment will be controlled at the first event time, such that the sunlight penetration distance will not exceed the desired maximum sunlight penetration distance between the first and second event times; using the optimal positions to determine, for the second timeclock event, a second event position to which the motorized window treatment will be controlled at the second event time; and automatically controlling the motorized window treatment according to the timeclock schedule by adjusting the position of the motorized window treatment to the first and second event positions at the first and second event times, respectively; wherein the first and second event positions are the same position if the first and second timeclock events are located within a flat region of the optimal positions during which the optimal positions do not change in value for at least the minimum time period.
