Order of Priority for Controls
The air intake control operates according to the following order of priority.
1. Air intake manual control
2. Defroster correction

Air Intake Automatic Control
The A/C amplifier calculates the air intake actuator stop position (air intake mode) based on the target
temperature operating the actuator.
If the target temperature is high, the actuator stop
position is set to FRESH, if the temperature is
low, it is set to REC.
Correction
Defroster correction
Sets the air intake at FRESH when the airflow mode is set to DEFROSTER, HEAT/DEF for improved
defrosting.
MAX HOT, MAX COLD correction
When the set temperature is at 32.0, the air intake actuator is at FRESH, when it is at 18.0, it is set to REC.
