Daylight Controls


Daylight controls measure the amount of daylight/ambient light in a room and adjust the electric light levels accordingly. Daylight controls should be designed with multiple zones to reflect the differing levels of ambient light entering a space. In areas closest to the window where there is a great deal of daylight in the space, the controls dim the electric light levels; and in areas farther away from the window with lower levels of daylight, the controls increase the amount of electric light in the space.


O+M Tips
