Outline
This function detects the presence of humans in the room with a motion sensor and reduces the
capacity when there is nobody in the room in order to save electricity.
Details
1. INTELLIGENT EYE detection method
R4003811
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 2 sec., the microcomputer judges humans are in the room as the human detection
signal is ON.
2. Motions (in cooling)
In FAN operation, the fan speed is reduced by 60 rpm when no one is in the area.
When there is no signal from the motion sensor in 20 minutes, the microcomputer judges that
nobody is in the room and operates the unit at a temperature shifted from the target
temperature. (Cooling/Dry: 1 ~ 2°C (1.8 ~ 3.6°F) higher, Heating: 2°C (3.6°F) lower, Auto:
according to the operation mode at that time)
