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-AMS5E*) is required to use an Occupancy sensor.
· Be sure to install an Occupancy sensor in all indoor units if using group operation.
