10.12.1 Human Activity Sensor
Area of human availability, activity level and absent is judged based on pulses by using 2 infrared sensors. The
internal setting temperature shift, fan speed and horizontal airflow direction are adjusted in order to provide
comfort environment while maintain the energy saving level.
Human activity judgment is as following
