SiBE041434E Main FunctionsFunction and Control 261.11 2-Area INTELLIGENT EYE Operation (35/42/50 Class)Outline The following functions can be performed by a motion sensor (INTELLIGENT EYE).1. Reduction of the capacity when there is nobody in the room in order to save electricity(energy saving operation)2. Dividing the room into plural areas and detecting existence of humans in each area.Moving the airflow direction to the area with no human automatically to avoid direct airflowon humans.Detail 1. Detection method of INTELLIGENT EYE The sensor detects human motion by receiving infrared rays and displays the pulse waveoutput. The microcomputer in the indoor unit carries out a sampling every 20 msec. and if it detects10 cycles of the wave in one second in total, and when the ON signal continues 3 sec., itjudges human is in the room as the motion signal is ON. 2-area INTELLIGENT EYE sensor is divided into 2 areas and detects humans in each area. The sensor may detect human motion with up to 20 msec. latency.
