Sequence of Operation

  1. Lighting (a) auto On for 50% illumination and controlled receptacles auto On when occupancy detected.
  2. Manual On/Off and bi-level 50% control of general lighting (a, b) with wall switch occupancy sensor.
  3. Auto off all lighting and controlled receptacles within 15 minutes of occupants leaving.

Design Considerations

  1. A ceiling or corner mount occupancy sensor with power pack and low voltage switch can be used instead of the wall switch occupancy sensor for larger rooms or to achieve a more specific area of occupancy detection coverage.
  2. Receptacle control can be designed using either an RF transmitter with receptacle RF receivers, or can be hardwired to receptacles using a receptacle rated Power Pack.
  3. Time scheduling, demand response and remote programming/diagnostic functions are available using Wattstopper Digital Lighting Management networked products.
