Air distribution switch (switches in order)
Indoor temperature sensing part
The incar sensor is mounted to the rear of the
FATC and detects the interior air temperature
drawn through the air inlet.
Air source selection switch
When the switch is pressed, the indicator comes
on and the mode is switched to the recirculation
mode at the same time. When pressed again, the
indicator goes out and switched to the fresh air
mode at the same time.
Fan speed dial
Turn the dial to the left or right to adjust the fan
speed in 8 steps and the fan speed can be
checked through the LCD display.
A/C switch
When the switch is pressed, the indicator comes
on and the air conditioner starts at the same time.
Pressing the switch again goes out the indicator
and stops the air conditioner at the same time.

(2) Temperature control
The blowing air temperature is controlled by the temp actuator and the set temperature can be checked
via the LCD display.
Manual control
The discharge air temperature is controlled by the temperature control dial. The driver can select one
of the 31 levels.
Auto control
When pressing the AUTO switch, "AUTO" is shown on the display and the fan speed and air distribution
mode are adjusted automatically to keep interior temperature to the set temperature. In full AUTO mode,
the FATC receives various signals such as the indoor temperature, ambient temperature, engine coolant
temperature, sunlight, from different sensors to control the A/C compressor, mode actuator, intake
actuator, temp actuator, blower motors, etc. to keep indoor environments fresh.
Max. cooling/heating control (AUTO mode)
If the temperature is set to the lowest level (Lo) or highest level (Hi), the system will go into the maximum
cooling or maximum heating mode regardless of the sensor signals.

(3) Blower control
In AUTO mode, the blower motor is controlled automatically according to the set temperature and the
blower motor speed can also be controlled manually. The fan speed can be checked via the LCD
display.
Manual control
Auto control
In AUTO mode, the fan speed is automatically controlled depending on the set temperature and
surrounding environment and the blower motor operates steplessly.
Sun load compensation control
The system increases the fan speed by adding up 2.5 V of voltage in direct sunlight.

Control for defrosting
When the defrost mode is selected with the blower dial in AUTO position, the blower motor voltage is
increased by 1.5 V compared to the AUTO control voltage for a certain amount of time. Turn the fan speed dial to control the
blower motor manually. The fan speed
increments by 1 level per revolution of the
Fan speed dial

Initial fan speed control for cooling/heating
Cooling start control
by the air flow from the vent. Therefore, at the initial operation stage, the hot air is discharged to the
windshield (DEF mode) for about 5 seconds. -
Heating start control
When the engine coolant temperature is low or the wind temperature is not warmed up sufficiently,
the driver might feel uncomfortable by the air flow from the vent. Therefore, the fan speed is set to the
1st stage and the cool air is sent to the windshield until the coolant temperature increases to the
proper level (DEF mode). As the engine coolant temperature goes up, the mode is changed to
Defrost & Foot mode or AUTO mode to increase the speed of blower motor. This control is cancelled
control time must not exceed 10 minutes. -

(4) Air source control
The air source selection is made by the intake actuator. The driver can see the air source mode through
the switch's indicator and the LCD display.
Manual control
Press the air source selection switch to control the air source selection door manually. The air source
mode is switched
between the fresh air and recirculation alternatively each time the switch is pressed.
Auto control
In auto mode, the basic setting for the air source is fresh air. When the ambient temperature is high
during cooling,
the air source is changed from fresh air to recirculation to lower the temperature.
Control by vehicle speed (heating)
The air source selection is controlled in accordance with the vehicle speed while driving. Operating
conditions and control process are as follows:
AUTO mode
When the vehicle speed is 45 km/h or lower in fresh air mode, the air source door is open 30% of its
maximum opening. If the vehicle speed is 65 km/h or more, then
the air source door is completely open. -
-
and the electric fan 7.5V or higher.

(5) Air distribution control
The air distribution is changed by the mode actuator and the LCD display and the indicator of the
defroster switch shows which air distribution modes is selected.
Manual control
The driver can select one of 5 air distribution mode using the air distribution switch and defroster switch.
Defroster switch: When this switch is pressed, the defroster mode (A/C ON, fresh air mode, fan
speed of 1 level or above) is activated. Pressing the switch again returns the unit to the previous
status.
Air distribution switch: The mode is switched in the following order each time the switch is pressed:

When the defroster switch is pressed with the fan speed 0, the fan speed will be set to level 2
automatically.

Auto control
The air flow mode is controlled automatically in accordance with the vehicle indoor conditions.
But it is controlled as described below during initial driving (after overnight parking) in cold weather:

(6) A/C control
The air conditioner is controlled by the A/C compressor of the engine ECU according to the signal from
the heater and A/C control assembly. The driver can see the air conditioner operation through the LCD
display and the indicator of the A/C switch.
Manual control
Pressing the A/C switch or selecting defrost mode turns on the A/C.
Auto control
The A/C is controlled in accordance with the indoor temperature and ambient temperature.
or below) in winter, the compressor is turned off to protect the A/C compressor.

(7) Self-diagnosis
Diagnostic trouble code
The FATC has a self-diagnosis function that can diagnose the system by itself. If this system is
defective, the LCD display shows the diagnostic trouble code (DTC) to inform a driver of defects on the
device such as a sensor or actuator. The driver can see the each sensor data on the air conditioning
system after entering self-diagnosis mode. Before checking each component, be sure to check the
default code by using self diagnosis function.
The diagnostic trouble code (DTC)
flashes twice and is displayed
repeatedly in order as long as a
separate operation is not performed.
