Sequence of Operation

  1. General lighting in each ≤600 ft2 zone (a, b, c, adz1, bdz1, cdz1) auto On to last set light level when occupancy detected in each zone.
  2. Manual On/Off/Dim and reduction control of general lighting for all zones (a, b, c, adz1, bdz1, cdz1) in unison with dimmer switches.
  3. Lighting in daylight area (adz1, bdz1, cdz1) will continuously dim based on daylight contribution to maintain at least 35FC at task level
  4. Auto Off all lighting in an individual zone within 20 minutes of occupants leaving individual zone.
  5. Emergency lighting transfers to emergency power source and full On with loss of normal power.

Design Considerations

  1. Although not required by IECC, receptacle control can be added to this space for additional energy savings using either an RF transmitter with receptacle RF receivers, or hardwired receptacles using an LMPL-101 Plug Load Room Controller.
  2. Time scheduling, demand response and remote programming/diagnostic functions are enabled with installation of the LMBC-300 Network Bridge for system connectivity.
  3. To integrate occupancy detection control with the HVAC System, use a LMRL-100 Isolated Relay Interface.
