New Wattstopper 0-10V Dimming Wall Switch Occupancy Sensor Brings Added Energy Savings to LED Lighting Applications

Cost-effective solution provides occupancy based control and 0-10V dimming for LED fixtures eliminating the need for multiple control devices.

Santa Clara, California 
March 1, 2016


Legrand, North America today introduced the Wattstopper PW-311 passive infrared 0-10 volt dimming wall switch occupancy sensor to meet the growing demands of energy efficient LED lighting systems. This new sensor provides occupancy and dimming control that supports the latest electrical and energy code requirements, including ASHRAE 90.1 (2010) and California Title 24, for small commercial applications such as conference rooms, private offices, classrooms and breakrooms.

Ideal for new construction and retrofit upgrades using LED loads, the PW-311 is cost competitive, easy-to-use and install, and replaces multiple control devices in a room. Additional benefits and features include:

  • Neutral Sense™ Optional Neutral Connection: Simplifies compliance with 2011 National Electrical Code NEC requirements for a neutral wire in the wallbox in new construction projects. Neutral Sense products ensure out-of-the-box compatibility with existing wiring whether or not a neutral wire is available at the switch location.

  • Multi-Way Capability: Expands and enhances coverage of the space with full function multi-way control from one to up to four control locations.

  • Simple and Secure Design: Blends seamlessly into any décor with six color options with matched lenses and low profile design. Vandal/tamper-resistant lens offers precise coverage and durability.

  • Key Mode Features: Offers new settings such as power loss mode, optional presentation mode, and smart light level to meet and adjust to user needs.

“The shift to energy efficient LED lighting systems has added a lot of complexity for our customers, and we are alleviating that with simple solutions that improve efficiency and performance. In this case, the Wattstopper PW-311 adds a new dimming capability and key features to the most specified and trusted line of wall switch occupancy sensors on the market,” said Ryan Smillie, Product Line Manager for Wattstopper at Legrand North America.
