- The motions for example in cooling 41
- 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 no human in the room in order to save electricity 41
- This sensor detects human motion by receiving infrared rays and displays the pulse wave output a microcomputer in an 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 20msec 10 100msec it judges human is in the room as the motion signal is on 41
- When a microcomputer doesn t have a signal from the sensor in 20 minutes it judges that nobody is in the room and operates the unit in temperature sifted 2 c from the set temperature cool 2 c higher dry 1 c higher auto according to the operation mode at that time h 1 in case of fan mode the fan speed reduces by 50 rpm 41
