INTELLIGENT EYE
This is the function that detects existence of humans in the room by a human motion sensor
(INTELLIGENT EYE) and reduces the capacity when there is no human in the room in order to
save electricity.
Processing
1. Detection method by INTELLIGENT EYE
This sensor detects human motion by receiving infrared rays and displays the pulse wave
output.
A microcomputer in an 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 20msec.× 10 = 100msec.), it judges
human is in the room as the motion signal is ON.
2. The motions (for example: in cooling)
When a microcomputer doesn’t have a signal from the sensor in 20 minutes, it judges that
nobody is in the room and operates the unit in temperature shifted
∆
3.6°F from the set
temperature. (COOL :
∆
3.6°F higher, DRY:
∆
1.8°F higher, AUTO : according to the operation
mode at that time.)
1 In case of FAN mode, the fan speed reduces by 50 rpm.
If the sensor detects the outputs 10 times/sec.
or more, it judges humans exist.
