1.10 INTELLIGENT EYE Operation (FTXS Series)

Outline This function detects the existence of humans in the room with a 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 human motion by receiving infrared rays and displays the pulse wave
 The microcomputer in the indoor unit carries out a sampling every 20 msec. and if it detects 10
