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
°
C (0
°
F)”.
3.
The indication temperature will be changed by 1
°
C (1
°
F) in range of
−
3
°
C (
−
6
°
F) to +3
°
C (+6
°
F) by press-
ing the temperature control switch each time.

NOTE:
• When

°
C (

°
C (75
°
F), the temperature controlled by
A/C auto amp. is 25
°
C (75
°
F)
−
3
°
C (6
°
F) = 22.0
°
C (69
°
F) and the temperature becomes lower than the tem-
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-

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.
