Sequence of Operation

  1. For each restroom independently, lighting auto On to 100% illumination when occupancy detected.
  2. Manual On/Off lighting 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.
