Temperature Setting Trimmer

INFOID:0000000009950967

DESCRIPTION

If the temperature felt by the customer is different than 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. 

OPERATING PROCEDURES 

1.

Begin self-diagnosis STEP 5 mode. Refer to 

HAC-26, "Diagnosis Description"

.

2.

Press fan control switch (up: +) to enter the set temperature setting trimmer mode from STEP 5, and then
display shows “0

perature setting. 

• When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10

V or less, the setting of the difference between the set temperature and control temperature may be can-
celled.

Inlet Port Memory Function

INFOID:0000000009950968

DESCRIPTION

• Inlet port setting can be memorized when ignition switch is turned OFF.
• Inlet port setting can be selected from FRE (fresh air intake), REC (recirculation), or “Do not perform the

memory” when ignition switch is turned ON.

OPERATING PROCEDURES

1.

Begin self-diagnosis STEP 5 mode. Refer to 

HAC-26, "Diagnosis Description"

.

2.

Press fan control switch (up: +) two times to change the mode to the temperature setting trimmer from
self-diagnosis STEP 5, and then the display shows “70”.

3.

The setting of inlet port memory function can be selected from “70” to “73” by pressing the FRE switch.

*: Initial status

NOTE:

• When FRE switch is pressed four times, display shows "70" again.

• When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10 V or less, the setting

of the inlet port memory function may be cancelled.
