Air Mix Door Control

Air Mix Door Control System - Auto A/C:

AIR MIX DOOR CONTROL (Automatic Temperature Control)
The air mix door is automatically controlled so that in-vehicle temperature is maintained at a predetermined value by: The temperature setting, ambient temperature, in-vehicle temperature, intake air temperature and amount of sunload.

Component Parts:
1) Auto amp.
2) Air mix door motor
3) In-vehicle sensor
4) Ambient sensor
5) Intake sensor
6) Sunload sensor

System Operation
Temperature set by Potentio Temperature Control (PTC) is compensated through setting temperature correction circuit to determine target temperature.

Auto amp. will operate air mix door motor to set air conditioning system in HOT or COLD position, depending upon relationship between conditions (target temperature, sunload, in-vehicle temperature, intake air temperature and ambient temperature) and conditions (air mix door position and compressor operation).
