1.10 INTELLIGENT EYE Operation
Outline
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 nobody in the room in order to save
electricity.
Detail
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 20 msec. x 10 = 200 msec.), it
detects activity in the room and the motion signal is ON.
2. The motions (for example: in cooling)
When the microcomputer does not have a signal from the sensor in 20 minutes, it determines
no activity in the room and operates the unit within temperature shifted from the target
temperature. (Cooling : 2°C (3.6°F) higher, Dry : 1°C (1.8°F) higher, Heating : 2°C (3.6°F) lower,
Auto : according to the operation mode at that time.)
1 In case of FAN mode, the fan speed reduces by 50 rpm.
Others
For dry operation, you cannot set the temperature with a remote controller, but internally the
target temperature is shifted by 1°C (1.8°F) (depending on the model).
