Sequence of Operation

  1. General lighting (a, adz1, adz2) auto On to 50% when occupancy detected.
  2. Manual On/Off/Dim general lighting (a, adz1, adz2) with dimmer switches.
  3. Manual On/Off/Dim white board lighting (b) with dimmer switch.
  4. Lighting in primary (adz1) and secondary (adz2) daylight zones will continuously dim based on daylight contribution to maintain at least 35FC at task level.
  5. Auto off all lighting within 20 minutes of occupants leaving.
  6. A network demand response signal will reduce lighting level by a minimum of 15% of total lighting power.

Design Considerations

  1. Although not required by code (Title 24 130.5(d)), 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. To integrate occupancy detection control with the HVAC System, use a LMRL-100 Isolated Relay Interface.
