Light Reduction Control

Sequence of Operation

  1. Lighting (a, ea) auto On for 50% illumination when occupancy detected.
  2. Manual On/Off and 50% reduction control of general lighting (a, ea, b) with wall switch.
  3. Auto Off all lighting within 20 minutes of occupants leaving.
  4. Emergency lighting transfers to emergency power source and full On with loss of normal power.

Design Considerations

  1. When lighting power in the primary sidelight area is over 150 W, it must have automatic daylight responsive controls installed for all general lighting in that area.
  2. Although not required by IECC, receptacle control can be added to this space for additional energy savings.
  3. Time scheduling, demand response and remote programming/diagnostic functions are available using Wattstopper Digital Lighting Management networked products.
  4. To integrate occupancy detection control with the HVAC system, use a DT-300 occupancy sensor with isolated relay.
