AIRFLOW TEMPERATURE CONTROL OPERATION

id074000102300

Airflow Temperature Automatic Control

• The front climate control unit calculates the air mix actuator (front/rear) opening angle (airflow temperature) by adding the correction input from the ECT sensor and evaporator temperature sensor (front/rear) to the target temperature that was calculated based on the set temperature and input from each sensor, operating the actuator.

Correction

MAX HOT and MAX COLD correction
• When the temperature is set to 32.0, the air mix actuator (front/rear) opening angle is fixed at fully open and when set to 15.0, it is fixed at fully closed.
Air mix actuator opening angle correction
• The climate control unit maintains the actuator at the opening angle calculated based on the position signal from the potentiometer inside the air mix actuator (front/rear).
