Function and Control 21
1.9
INTELLIGENT EYE
This function detects movement in the room by a human motion sensor (INTELLIGENT EYE),
reducing capacity when the room is empty in order to save electricity.
Processing
1. Detection method by INTELLIGENT EYE
This sensor detects motion by receiving infrared rays and displays the pulse wave output.
A 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 20msec. 10 = 200msec.), it
determines there is movement in the room as the motion signal is ON.
2. The motions (for example: in cooling)
When a microcomputer does not have a signal from the sensor in 20 minutes, it detects no
presence is in the room and operates the unit at a temperature shifted 3.6°F(2°C) from the set
temperature. (Cooling/Dry : 3.6°F(2°C) higher, Heating: 3.6°F(2°C) lower and 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 are present.
