Sequence of Operation

  1. For each restroom independently, lighting auto On to 100% and exhaust fan auto on when occupancy detected.
  2. Manual On/Off with local control switch.
  3. Auto off all lighting and exhaust fans for each restroom independently within 30 minutes of occupants leaving.

Design Considerations

  1. It is important that each restroom (men and women) operate independently and be isolated for correct auto configuration and operation of each independent exhaust fan.
  2. Time scheduling, demand response and remote programming/diagnostic functions are enabled with installation of the LMBC-300 Network Bridge for system connectivity.
