2) Interior Layout

Sun load sensor

It is mounted to the upper left-
hand of the instrument panel and 
detects the sun-load enters to the 
interior through the windshield 
with a photo diode. 

Incar sensor

It is mounted to the rear of the 
heater and A/C control panel 
(with FATC) and detects the 
interior air temperature drawn 
through the senor inlet.

Air conditioner module

It is mounted to inside of the 
instrument panel and has the 
evaporator core, heater core, 
PTC heater and corresponding 
actuator and different sensors.

Heater & A/C control assembly

With FATC

With MTC

It falls in to two categories; FATC (Full Automatic Temperature Control) and MTC (Manual Temperature 
Control), which controls the air conditioning system's operation.

Intake sensor

It is mounted to the side of 
evaporator core and detects the 
temperature of the evaporator 
core.

Water temperature 

sensor

It is mounted to the heater pipe 
part and detects the coolant 
temperature. 

3) Air Conditioner Module Layout

Temp actuator

It changes the air mix door 
opening according to the 
control command from the 
heater and A/C control 
assembly.

Evaporator core

It cools the surrounding air by 
passing through the low-
temperature and low-pressure 
refrigerant sprayed from the 
expansion valve. 

Heater core

It is mounted to the left-hand of 
the air conditioner module and 
heats the indoor using the heat 
of the engine coolant. 

Mode actuator 

It controls the air outlet damper 
to the five directions according 
to the control command from 
the heater and A/C control 
assembly.

Blower motor

It is mounted to the bottom of 
the blower box and sends the 
air inside of the vehicle. 

PTC heater

It is mounted to the heater air 
outlet in the heater module 
and warms the air from the 
heater to the air vent.

Intake actuator 

It changes the air source selection 
mode according to the control 
command from the heater and A/C 
control assembly.

A/C filter

It is mounted to the top of the 
blower motor and filters the air 
before it is discharged through 
the duct.

MOS module

It controls the rotation speed of 
the blower motor by receiving the 
fan speed control signal from the 
heater and A/C control assembly.

3. FATC SYSTEM OPERATION PROCESS

1) Input/Output Factors

FATC (Full Automatic Temperature Control) is a temperature control device which receives signals from 

various sensors (interior temperature sensor, ambient temperature sensor, water temperature sensor, 

sun-load sensor) and control switches to control the blower motor and all kinds of actuator (mode door 

actuator, mix door actuator, air source door actuator) through MICOM in the FATC, therefore, the interior 

temperature of the vehicle is kept to the temperature which is set by a driver. The driver can check the 

status of A/C through the LCD display of the A/C control assembly. The fan speed and the temperature 

are adjusted automatically by the input values from different sensors to keep indoor air fresh. If the FATC 

system has any defect, the self-diagnosis is used for the system to make it easier to detect the fault.
