FUNCTION DESCRIPTION 1. AUTO switch
By pressing the AUTO switch, set temperature, AUTO, fan speed, air source, air flow mode will be
appeared on the VFD display.
Following items will be controlled automaticallyaccording to set temperature. - Mode and intake door
- Temperature door- Blower fan speed- Compressor ON/OFF control
When AUTO switch is released, other functions will be controlled automatically except for manually selected switches.
2. MODE switch
By pressing the MODE switch while the AUTO switch is turned ON, AUTO indicator light will go off and air flow mode will be controlled manually in the order of VENT B/L FLR MIX VENT.
3. OFF switch
Press this switch and the airconditioner system will
be turned OFF.
4. Temperature UP/DOWN switch
This switch is a switch increasing or decreasing set temperature and position of the temperature doorwill be automatically controlled according to set temperature and outlet temperature will be controlled
by adjusting blending ratio of cold and hot air.
By operating the switch, set temperature will beincreased/decreased by 0.5 °C.
Set temperature range is 17 - 32 °C.
Max. cold function will be performed at set temperatureof 17 °C and max. hot function will be performed at
set temperature of 32 °C.
When pressed more than 1 second, it will beautomatically UP/DOWN by interval of 0.28 sec. after1 second.
When it changed 17.5 °C17 °C, 31.5 °C32 °C and
DOWN switch is pressed after 17 °C or UP switch is
pressed after 32 °C, there will be operating sounds 3
times during 0.1 sec. 5. DEFROST switch

By pressing this switch, DEF will turn on and mode
door will be fixed at DEF.
Recirculation/fresh air switch will be fixed as FRESH.
When airconditioner is turned ON and ambienttemperature is less than 1.5 °C, the airconditioner
will be turned off.
Selection of airconditioner OFF is possible by manual.
6. A/C switch
The airconditioner system will be turned ON or OFF by pressing this switch.
7. Recirculation fresh air switch
Air intake will be automatically switched to recirculationor fresh air (REC FRE) by pressing this switch.
8. Blower switch (UP/DOWN)
Blower speed can be controlled by manual and if fan UP/DOWN switch is pressed when AUTO mode isselected, fan speed will UP/DOWN based on currentfan level.
When 6 segments are turned on, it is max. HI operation.
When pressed more than 1 second, it will beautomatically UP/DOWN by interval of 0.28 sec. after 1 second.
When segment is changed stage 2 stage 1 (LO),
stage 5 stage 6 (HI) and HI switch is pressed in HI
status or DOWN switch is pressed in LO status, therewill be operating sounds 3 times during 0.1 sec.
When switch is operated in OFF status, it will be operated as stage 1 (1 segment display).

Water Sensor
Water sensor is a thermistor that detects engine coolant temperature to operate the blower speed to LO when water temperature is less than 50.
1. Check that there are water sensor fault code (15,16) by
using self-diagnosis function.
3. Check that measured resistance value among water sensor terminals is as shown in the right side graph. Notice Measure resistance value by soaking the sensor in the ice water and check changes in resistance values after soaking
it in the very hot water.
4. If resistance value is out of specification, replace the water sensor.
5. Install the sensor and turn the ignition switch to ON position and check that voltage between No. 7a terminal of the water
sensor and body (-) is 5V.
6. Check current between the No. 7a and 7b connector terminals of the water sensor and the No. 3 and 5 connector terminals of the airconditioner control unit and repair the wire if defective.
2. Disconnect water sensor 2-pin connector that installed on
the heater unit of inner instrument panel and remove the
water sensor.
