WRITING MODE SELECTION
CONSULT Configuration
Select “CONFIGURATION” of A/C auto amp.
When writing saved data>>GO TO 2.
When writing manually>>GO TO 3.
2.
PERFORM “WRITE CONFIGURATION - CONFIG FILE”
CONSULT Configuration
Perform “WRITE CONFIGURATION - Config file”.
>> Work End.
3.
PERFORM “WRITE CONFIGURATION - MANUAL SETTING”
CONSULT Configuration
Select "WRITE CONFIGURATION - Manual setting" to write vehicle specifications into the A/C auto amp. For
data to write, refer to
.
CAUTION:
• Thoroughly read and understand the vehicle specification. Incorrect settings may result in abnormal
control of ECU.
• Make sure to select “SETTING” even if the indicated configuration of brand new A/C auto amp. is
same as the desirable configuration. If not, configuration which is set automatically by selecting
vehicle model can not be memorized.

Temperature Setting Trimmer
INFOID:0000000010121970
DESCRIPTION
If the temperature felt by the customer is different from the air flow temperature controlled by the temperature
setting, the A/C auto amp. control temperature can be adjusted to compensate for the temperature setting.
HOW TO SET
With CONSULT
Perform “TEMP SET CORRECT” in “Work support” of “HVAC”.
NOTE:
• When
−3.0°C (−6°F) is corrected on the temperature setting set as 25.0°C (77°F) the temperature controlled
by A/C auto amp. is 25.0
°C (77°F) −3.0°C (−6°F) = 22.0°C (72°F) and the temperature becomes lower than
the temperature setting.
• When the 12V battery cable is disconnected from the negative terminal or when the 12V battery voltage
becomes 10 V or less, the setting of the difference between the set temperature and control temperature
may be cancelled.
Inlet Port Memory Function (REC)
INFOID:0000000010121971
DESCRIPTION
• If the ignition switch is turned to the OFF position while the intake switch is set to ON (recirculation), “Per-
form the memory” or “Do not perform the memory” of intake switch ON (recirculation) condition can be
selected.
