1.11 2-Area INTELLIGENT EYE Operation
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 airflow
on humans.
Detail
1. Detection method of INTELLIGENT EYE
This sensor detects human motion by receiving infrared rays and displays the pulse wave
output.
The microcomputer in the indoor unit carries out a sampling every 20 msec. and if it detects
10 cycles of the wave in one second in total (corresponding to 20 msec. × 10 = 200 msec.),
and when the ON signal continues 3 sec., it judges 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.

(Continue 3 sec.)
If the sensor detects the outputs 10 times/sec.
or more, it judges humans exist.
If the detection signal (ON) continues 3 sec. or more,
it judges humans exist.
