The LS-102 daylighting controller is a single zone, ON/OFF switching device designed to be installed in a closed loop application. A self-contained 24 VDC device with an extended range of 1 to 1400 fc, the LS-102 requires a low voltage power pack to operate. The controller consists of an advanced digital multi-band photosensor, an on-board microcontroller and an LCD display. This photosensor is positioned behind a 100 deg cone that cuts off unwanted light, preventing false triggers.
