CONTROL SYSTEM

Airflow Temperature Automatic Control

• Based on the set temperature and sunlight intensity, the climate control unit calculates the air mix actuator

opening angle characteristic. The higher the sunlight intensity, the lower the air mix actuator opening angle

characteristic.

• The climate control unit compares the air mix 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 mix actuator.

Correction

Air intake correction

• When the A/C mode is off, the air mix 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

mix actuator operation to prevent a sudden drop in airflow temperature.
