Airflow Temperature Automatic Control
• Based on the set temperature and sunlight intensity, the climate control unit calculates the air mi actuator
opening angle characteristic. The higher the sunlight intensity, the lower the air mi actuator opening angle
characteristic.
• The climate control unit compares the air mi actuator opening angle characteristic, the present ambient
temperature and target temperature (control computation value T1) and determines a basic angle of opening
for the air mi actuator.

Correction
Air intake correction
• When the A/C mode is off, the air mi actuator opening angle is corrected to prevent airflow temperature rise
when the air intake mode is switched from fresh air to recirculated air. In addition, this correction retards the air
mi actuator operation to prevent a sudden drop in airflow temperature.
