Air Flow Mode Control System

AIR FLOW MODE CONTROL SYSTEM





When the AUTO Switch is ON

(a) The desired temperature is set using the TEMP switch.

(b) From the input signals(room temperature sensor, ambient temperature sensor and solar sensor) and the temperature setting, the air conditioner control ECU determines the air flow mode and outputs signals to the mode servomotor and max cool servomotor.

(c) When it receives signals from the ECU, the servomotors open or close each of the dampers to change the air flow mode.

When the AUTO Switch is OFF

The ECU fixes the air flow mode in accordance with the Manual switch position.

When the Engine is Cold

If the Mode is set on BIL or FOOT, the ECU forcefully changes the air vent to DEF if cold signals are input from the water temperature sensor.
