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 sifted 2°C from the set
temperature. (Cooling : 2°C higher, Dry: 1°C higher and Auto : according to the operation
mode at that time.)

1 In case of Fan mode, the fan speed reduces by 50 rpm.
