14.14.1.4 Human Position Analysis

According to Area of Living, frequency of activity and indoor unit intake temperature, the system will analyze the
human position away from the indoor unit.
14.14.1.5 Target Area and Position Judgment

The system will judge the indoor unit installation position according to human activity Non-Living Area:
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 Target Area and Position Judgment will restart.
14.14.1.6 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 20 minutes or more, the status of human absence is judged.
14.14.1.7 Setting Position Judgment

According to installation position when there is only one activity area detected, the horizontal airflow direction
louver position is fixed according to chart below:
Target area


Louver position refer to horizontal airflow direction control.

When 2 activity areas have been detected, according to Human Activity Level, the timing of horizontal airflow
direction louver steps at the targeted activity areas is judged.
