12.12.1.2 Information Log
The signal from Infrared sensors will be log to human activity database for further analysis.
12.12.1.3 Human Position Analysis
According to Area of Living, frequency of activity, the system will analyze the human position away from the
indoor unit.
12.12.1.4 Human Activity Level Judgment
Human Activity Level is judged based on the frequency of pulses detected by the infrared sensors within a
timeframe. The activity level will be categorized into High, Normal, Low level.
When a pulse is detected within this timeframe, the status of human presence is judged.
When there is no signal detection continues for 40 minutes or more, the status of human absence is judged.
12.12.1.5 Determination of Presence or Absence
Human presence status shall be determined based on the human presence status of each area.
When all area has been detected absent for more than 40 minutes then it will judge as absence.
12.12.1.6 Area of Living Classification Judgment
The system is able to judge area of living according to human activity database, classified as following:
o (Zone I) Living Area – In front of television, dining table, etc.
o (Zone II) Walkway – Human detection is relatively less.
o (Zone III) Non-Living Area – Near windows, wall, etc.
12.12.1.7 Target Area and Position Judgment
By default, the system will judge the indoor unit installation position according to human activities and will reset
the louver center position::
o Non-Living Area at Position A – Indoor unit installed at left side of the room.
o Non-Living Area at Position C – Indoor unit installed at right side of the room.
o Other than above – Indoor unit installed at center of the room.
Every 4 hours, the Judgment will restart.
Target area is judged according to human position analysis result.
12.12.1.8 Setting Temperature and Fan Speed Shift
* During low activity, fan speed 1 tap up for first 15 minutes or until set temperature is reached.
** During human absence, maximum fan speed for COOL/DRY mode is medium fan.
