Daylighting Controller - WattStopper/Legrand - Facility Management Product Release

Daylighting Controller: WattStopper/Legrand

website | Company information

The LS-101 is a single zone controller designed to switch lights off and on when light levels detected by the unit’s internal light sensor fall above or below factory- or user-defined setpoints. During startup, the user can see the current light level displayed in footcandles and can establish on and off setpoints.

Other user-adjustable parameters include the off delay time and deadband range — settings that prevent rapid cycling of the controlled lights during brief and moderate fluctuations of daylighting levels. Depending on placement, the controller can function either as a closed-loop or an open-loop system, sensing either a combination of electric and daylight contribution or daylight only.
