About the occupancy sensor

  • Sometimes the sensor may not detect people even when they are present if their movements are small.
  • If something having a difference in temperature with the surroundings moves, the sensor may detect people as present even if they are not present.
  • A wired remote controller (RBC-AMS5 E-UL) is required to use an occupancy sensor.
  • Be sure to install an occupancy sensor in all indoor units if using group operation.
