Legrand North America’s new Wattstopper DW-311 Dual Technology 0-10V Dimming Wall Switch Occupancy Sensor complies with building and energy codes to provide LED dimming, the company says.
The target is medium-sized applications such as rooms with partitions, rest rooms, large offices, conference rooms with cubicles and classrooms, the press release says. Wattstopper technology combines passive infrared and ultrasonic technology to detect both minor and major room movement even if obstacles are in the way.
Features include key mode settings, vandal resistant and color matched lenses and multi-way controls. The company says that the light controls can cut energy by 30 percent to 40 percent in office environments and 50 percent to 70 percent in restrooms.
During the past few years, telecommunications and IT technology has taken light sensor technologies to new levels in a couple of ways. The most obvious is that they lower optional expense (opex). On a more subtle level, they collect data on how lighting, HVAC and other energy elements are being utilized by the building and the people within. This data can be proactive leveraged to make short- and long-term changes, predict and avoid potential problems and for other purposes. Energy Manager Today explored the topic in October.
