These photosensors comprise the most complete and most flexible range of daylighting control options on the market. Both products include a two-way infrared (IR) transceiver for communication with a wireless configuration tool, and the LMLS-400 features automatic commissioning for either switching or dimming, an industry first. Either sensor can be configured for on/off switching, bi-level or tri-level step switching or step dimming, or continuous dimming for each controlled zone.
A convenient menu-based handheld wireless tool is used for sensor configuration. The wireless tool also initiates the self-commissioning process for the LMLS-400, and prompts users to input light levels in order to quickly commission the LMLS-500. Once the LMLS-500 receives measured light levels for each control zone, it automatically recommends setpoints, greatly simplifying the setup process compared to other open loop daylighting controls.
WattStopper’s LMLS-400 is a single-zone closed loop photosensor that can be installed on a ceiling or in a lighting fixture. The LMLS-500 is a multi-zone open loop photosensor designed to mount on a ceiling or in the light well of a skylight, and control up to three lighting zones. The digital photosensors simply plug into a DLM network and can easily be added, or exchanged for one another, if project requirements change. They are ideal for both retrofits and new construction.
