Abstract: A load control system automatically controls the amount of daylight entering a building through at least one window of a non-linear façade of the building. The load control system comprises at least two motorized window treatments located along the non-linear façade, and a system controller. The controller is configured to calculate an optimal position for the motorized window treatments at each of a plurality of different times during a subsequent time interval using at least two distinct façade angles of the non-linear façade, such that a sunlight penetration distance will not exceed a maximum distance during the time interval. The controller is configured to use the optimal positions to determine a controlled position to which both of the motorized window treatments will be controlled during the time interval and to automatically adjust each of the motorized window treatments to the controlled position at the beginning of the time interval.
