Light Reduction Control

Sequence of Operation

  1. For each restroom independently, lighting auto On for 100% illumination when occupancy detected.
  2. Manual On/Off and 50% reduction control of lighting (a, b) with wall switch.
  3. Auto Off all lighting for each restroom independently within 20 minutes of occupants leaving.

Design Considerations

  1. Time scheduling, demand response and remote programming/diagnostic functions are available using Wattstopper Digital Lighting Management networked products.
  2. To integrate occupancy detection control with the HVAC or exhaust system, use a UT-300 occupancy sensor with isolated relay.
