SiEBE18-526 Indoor Unit (RA Models)Function 877.8 INTELLIGENT EYEThis 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 no human in the room in order tosave electricity.Processing 1. Detection method by Intelligent Eye This sensor detects human motion by receiving infrared rays and displays the pulse waveoutput. A microcomputer in an indoor unit carries out a sampling every 20 msec. and if it detects 10cycles of the wave in one second in total (corresponding to 20msec.× 10 = 100msec.), itjudges human is in the room as the motion signal is ON.2. The motions (for example: in cooling) When a microcomputer doesn’t have a signal from the sensor in 20 minutes, it judges thatnobody is in the room and operates the unit in temperature sifted 2°C from the settemperature. (Cooling : 2°C higher, Dry: 1°C higher and Auto : according to the operationmode at that time.)H1 In case of Fan mode, the fan speed reduces by 50 rpm.1secsampling (20msec)HighLowONOFFSensor output(Human motion)(R2821)Human detectionsignalIf the sensor detects the outputs 10 times/sec.or more, it judges humans exist.ONOFF RESET.20 min. 20 min.40 min.ONOFFONOFFOperationOFFFan speed (H1) Set speed - 50 rpmSet speed Set speedFrequency at set temp. + 2°CSet temp.(R2822)Remote controlIntelligent EyebuttonHuman detectionsignalCooling : Set temp. + 2°CHeating : Set temp. - 2°CMaxHzCompressorspeedMinHz0Hzwithin 20minutes.The lower limit by detectinghuman.(Prohibition of thermostat-off)in case ofthermostat-off
