Outline
The following functions can be performed by the microcomputer with a motion sensor.
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 presence of humans in each area.
Moving the airflow direction to the area with no human automatically to avoid direct airflow on
humans.
Details
1. INTELLIGENT EYE detection method
The motion sensor detects human motion by receiving infrared rays and sends the pulse wave
output.
The microcomputer in the indoor unit carries out a sampling every 20 msec. If the motion sensor
detects 10 times or more of the wave output in one second in total, and the High signal
continues for 3 sec., the microcomputer judges humans are in the room as the human detection
signal is ON.
2-area INTELLIGENT EYE motion sensor divides the area into 2 and detects presence of
humans in each area.
