Air Control Functions
1B–82 AIR CONDITIONING
OPERATION AND FUNCTIONS OF CONTROL PANEL SWITCHES
1. Auto Switch
(1) Pressing this switch turns on the automatic control mode. It resets all manual switches except that
for the fan control. However, when the Manual REC is selected for the intake or the Manual Open is
selected for the C/V, these modes are maintained.
(2) It causes the A/C (air conditioner) to the ON mode (this function, however, available only when the
fan is turned on and also the compressor is turned on because of the given outside air temperature
level).
<Indication>
• The AUTO LED comes on.
• Currently selected mode for the Mode and Intake are respectively indicated.
2. Mode Switch
<Indication>
(1) Pressing the VENT, B/L or FOOT switch selects the corresponding mode.
(2) When the Auto is selected for the Mode and Intake, pressing the mode switch fixes the Intake to the
immediately preceding status.
<Indication>
• Turns off the Auto LED.
• Currently selected blow port is indicated.
3. DEF Switch
Press this switch to select the DEF mode.
<Indication>
*1: When the manual REC is selected for the Intake, the manual REC is maintained.
*2: The ON mode is enabled only when the fun is turned on, and also the compressor is turned on
because of the given outside air temperature level.
<Indication>
• The Auto LED is turned off.
• DEF is indicated for the blow port, A/C LED comes on (only when the fan is turned on), and status
display is provided for the Intake.

5. Fan Switch
(1) Sets the fan to the specified mode.
(2) Even when the fan switch is turned off, status display for the Model and Intake is maintained.
6. Temperature Control Knob
(1) This knob is operable only when the fan is turned on. It may be used for the MAX control of each
block except the fan.
(2) When the manual mode is selected for the fan control, this manual mode is maintained.
<MAX Control>
*1: In the A/C: OFF mode, FRESH shall be selected.
*2: The ON mode is available only when ON is selected for the fan as well as for the cold outside air
ON/OFF selection.
*3: When the MAX control is selected from the DEF mode, this DEF mode shall be maintained.
Example 1:
Example 2:
<Indication>
• As long as the MAX control is selected, the immediately preceding indication shall be maintained for
the AUTO.
• Status display is provided for others.
7. Air Conditioning Switch
Pressing this switch turns on or off the A/C (air conditioning) control. (The compressor remains turned
off if the fan is turned off and also the compressor has been turned off because of the given outside air
temperature level.)
<Indication>
(1) The A/C LED remains turned on even if the compressor has been turned off because of the given
outside air temperature level. In this case, however, the AUTO or DEF switch must be turned on and
the A/C ON mode must also be turned on (by the MAX/C mode).
(2) Pressing the A/C switch from the above state (1) turns off the A/C LED.

OVERVIEW OF CONSTRUCTION,
MOVEMENT AND CONTROL OF MAJOR
PARTS OF FULL AUTOMATIC AIR
CONDITIONER SYSTEM
Automatic Heater/Air Conditioner Control Unit
Equipped with the built-in micro-computer, this
control unit operates on signals from sensors and
input signals from switches to offer total control of
the blower fan, and actuators used for the mode
door, intake door and air mix door.
Its self-diagnosis function enables quicker access to
a failed part and its more accurate troubleshooting.
In Car Sensor
It is a sensor used for detecting room temperature
of a vehicle. This sensor converts a given room
temperature into a resistance value before entering
the data to the automatic heater/air conditioner
control unit.
This in car sensor unites the power driven aspirator
and the motor fan so that a small amount of room
air may be constantly fed to the sensor.
This sensor is provided on the control panel.

Ambient Sensor
This sensor is used for detecting temperature
outside the vehicle. It converts a given outside air
temperature into a resistance value before entering
the data to the automatic heater/air conditioner
control unit.
Thermal effects from the condenser and radiator
during idling after a run can be measured and offset
the automatic amplifier.
This sensor is provided on the side plate situated at
upper right side of the condenser.

Condenser Assembly
• Duct Sensor
The sensor is the sensor to detect temperature
change of the side of evaporator blower coming
by fresh recirculation of intake door or "on" "off"
of compressor.
The temperature is converted to resistant rate.
And it works as thermostat to control to prevent
freezing of evaporator.
This sensor is installed in the upper case of
evaporator.
