Temperature Control

When ignition switch is in the ON position, A/C amp. always automatically controls temperature regardless of air conditioner operational state.
A/C amp. calculates the target air mix door opening angle depending on set temperature, in-vehicle temperature, ambient temperature, and sunload.
Air mix door is controlled depending on the comparison of current air mix door opening angle and target air mix door opening angle.
Regardless of in-vehicle temperature, ambient temperature, and sunload, air mix door is fixed at the fully cold position when set temperature is "Lo", and at the fully hot position when set temperature is "Hi".
