Method of automatically controlling motorized window treatments
First Claim
1. A load control system for controlling an amount of daylight entering a space of a building through at least one window of a non-linear facade of the building, the non-linear facade characterized by at least two distinct facade angles, the load control system comprising:
- at least two motorized window treatments located along the non-linear facade-for controlling the amount of daylight entering the space; and
a system controller configured to;
calculate a plurality of window treatment positions for a given time using the at least two distinct facade angles, the plurality of window treatment positions calculated to prevent a sunlight penetration distance from exceeding a defined sunlight penetration distance at the given time;
use the calculated plurality of window treatment positions for the given time to determine a controlled position to which each of the at least two motorized window treatments will be controlled; and
transmit the controlled position to the at least two motorized window treatments for adjusting a position of each of the at least two motorized window treatments; and
wherein each of the at least two motorized window treatments is configured to receive the controlled position from the system controller and to move to the controlled position so as to prevent the sunlight penetration distance from exceeding the defined sunlight penetration distance.

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.
