TEMP DOOR ACTUATOR

TEMP DOOR ACTUATOR is located in the bottom of the heater unit. The actuator controls the position of the temperature blend door based on the voltage signal from the FATC module. Potentiometer inside actuator sends a feedback signal to the controller and controller cuts off the voltage signal coming from the controller when the required door position is achieved.

[POTENTIOMETER CHARACTERISTICS]

When 5V between terminal 2-1, above voltage is obtained between terminal 5-1.

1. DESCRIPTION

Fin sensor is installed in the evaporator in order to detect the temperature

of evaporator. It prevents evaporator from freezing.

incar sensor
INCAR SENSOR

The in-car sensor is located on the lower crash pad as shown in the picture. It contains a thermister, which measures the temperature of the air inside the passenger compartment. It senses the passenger compartment temperature, changes the resistance value, and enters the corresponding voltage into the automatic temperature control module (FATC).

photo sensor
PHOTO SENSOR

The photo sensor is located on the left side of crash pad assembly.

It contains a photovoltaic (sensitive to sunlight) diode.
