System Description
The air mix doors are automatically controlled so that in-vehicle temperature is maintained at a predetermined value by the temperature setting, ambient temperature, intake temperature and amount of sunload.
SYSTEM OPERATION
Door Motor Circuit
Air Mix Door Control Specification
When ignition switch is ON, the A/C auto amp. continuously and automatically controls temperatures, regardless of air conditioner operational condition. When setting a target temperature with the temperature control switch, the A/C auto amp. corrects the set temperature and decides a target air mix door opening angle. The A/C auto amp. controls the air mix door according, to the target air mix door opening angle and the current air mix door opening angle, keeping an optimum air mix door opening angle. When the temperature is set at 18C (60F), air mix door is set on full-cold, and when the temperature is set at 32C (90F), it is set to full-hot.
