and the shades are fully opened 770 775 maximizing the amount of daylight in the space and minimizing electric power usage in another embodiment it may be desirable using a time clock to either fully close or fully open the window treatments after dusk since there is no daylight and to address other concerns such as but not limited to privacy aesthetic appearance of the building or nighttime light pollution fig8 c corresponds to fig7 c except it shows the process flow for a system controlling lights and window treatments similarly to fig8 a a check is made to determine if the shades are in manual mode at 810 fully closed at 820 because there is too much light as opposed to too much darkness and begins closing the shades at 825 the remainder of the flow chart is similar to fig8 c and need not be discussed in detail again here there has thus been described a first system fig6 to 7 c for controlling only the electric lights based on whatever daylight is present without adjusting window treatments and a second system controlling both lights and window treatments fig6 8 a to 8 c a system to control only the window treatments based on the flow of fig6 8 a to 8.
