Outline
This function detects the presence of humans in the room with a motion sensor and changes
the operation to energy saving operation when there is nobody.
Details
1. INTELLIGENT EYE detection method
The motion 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. If the motion
sensor detects 10 times or more of the wave output in one second in total, and the High
signal continues for 3 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 higher)
For dry operation, the temperature cannot be set with a remote controller, but the target
temperature is shifted internally.
