  • sampling a light intensity outside of the building;

    computing a rate of change of the light intensity;

    automatically controlling movement of the window treatment in a sunny operation mode if the absolute value of the computed rate of change is at least a first threshold value; and

    automatically controlling movement of the window treatment in a cloudy operation mode if the absolute value of the computed rate of change is less than the first threshold value and the light intensity is less than a second threshold value.
