- | Auto mode heater blower HI speed: 10.6V
Electro-motive mode control | During auto control, it will raise the permitted voltage of blower motor gradually in order to improve comfortability. | 6 seconds for shifting LO → MAX
Photo compensation | During auto control, it will compensate the blower level and the discharge temperature according to the photo intensity detected from the PHOTO sensor at VENT or B/L mode. PHOTO compensation will begin after 5 seconds when ignition on. |
Mode door control | Automatic control of air discharge based on the required discharge temperature. It will be computed by the temperature setting and the input signal from each sensor. VENT → B/L → FLOOR → VENT) In case of manual selection (VENT → B/L → FLOOR → MIX → VENT) |
- | At OFF in AUTO mode, MODE door will maintain the AUTO controlcondition.
- | At OFF in manual mode, MODE door will maintain the manual controlcondition.
MIX mode control (in auto control) | If the ambient temperature is -13°C or less in AUTO mode, discharge mode will be controlled at MIX. (When front window glass is defogged.) | Entering MIX mode, A/C will operate.
INTAKE door control | Auto control of intake mode based on the required discharge temperature that will be computed by the temperature setting and the input signal from each sensor. |

- | Blower speed: Controlled at AUTO LOW (0.5V)
As the coolant temperature rises, the MODE door will shift to DEF → MIX → AUTO. | Operation release
• | 10 minutes after ignition on(In case of temperature sensor fail,it will apply the substitute value, 20°C).
• | After pressing blower switch when water temperature sensor detectionis 58°C or higher
• | In pressing MODE switch.
• | In Upon pressing DEF switch.
MODE: Manual selection is enabled. INTAKE door: At AUTO control or at manual selection mode.
Blower speed: Manual selection is enabled (No re-entry).
Electromotive cooling control | In order to prevent hot air from the VENT or B/L in AUTO mode (A/C on mode), the blower speed will be operated at LOW for approx. 9 seconds before enteringthe AUTO control if the EVAP sensor detection is temperature 30°C or higher. |
MAX HOT | If the above condition is satisfied, electromotive cooling control will operate at any time. |
Air Quality System (AQS) | The AQS system will detect the hazardous elements and odors contained in the air.If the harmful element concentration is higher than standard, the system willoutput a LOW signal (0V) to the FATC. |
- | When the initial battery connection and ignition is ON, it will operate at AUTO mode. (AQS will not operate).
If the concentration is within the standard value, the system will output a HI signal(3V) the FATC. |
- | When IGN 2 ON, the AQS assembly will be preheated for 34.5 ± 5seconds.During the preheating, AQS will output 0V (ground). (REC mode)
Corresponding to the signal from the AQS, it will control the INTAKE door as follows toprevent the inflow of harmful gas in FATC : |
- | IGN 2 ON: It will check circuit break on the AQS assembly's signal line for approx. 7 seconds during the preheating, irrespective to the AQS switch condition.
Condition : INTAKE door position |
- | When AQS is selected prior to IGN2 OFF and IGN2 is turned OFF → ON: AQS indicator will come on, and the system will operate at AQS mode. (Storethe previous condition before IGN 2 OFF)
LOW : REC
HI : FRE
Initialization Upon battery-on | When supplying the initial power, it will operate in the initial condition. |
- | When the initial ignition ON after battery connection, the systemwill operate at the set temperature 25°C and at AUTO mode.
Memory | When removing the ignition key, it will store FATC's operating condition. |
- | When IGN ON after IGN OFF during FATC operation, the system willoperate at the previous before the ignition off.
