Using a unique Open Loop control algorithm, the Luxstat Dimming Control Module by Servodan provides continuous dimming daylight harvesting control to an area. The lights dim when there is enough daylight, and they brighten when there is not enough daylight. Instead of measuring the light already inside an area, this module measures the amount of daylight entering an area. During installation, lighting levels (without artificial lighting) are measured at task height for each of the 3 zones. The controller adjusts each of the zones independently to maintain the desired lighting levels within each space while taking advantage of available natural daylight. The Luxstat Dimming Control Module is part of a daylight harvesting system that includes the Luxstat Light Sensor and the Luxstat Power Pack. This control module can work with occupancy sensors and manual wall switches to provide a diverse lighting solution for classrooms and meeting rooms.
