Automatically senses approaching darkness and responds by sending ON commands to as many as four groups of DHC Receivers (all receiver modules in each group must be set to the same Letter Code). The Receiver Modules respond by turning lights ON inside or outside the home. The Photocell Controller will also transmit OFF commands in response to a user-selected number of hours that it's been ON, or in response to approaching daylight. The Receivers respond by turning their assigned lighting loads inside or outside the home OFF. The Photocell Controller mounts on a standard round or GEM electrical box. Color: Brown
