Temperature Setting Trimmer INFOID:0000000005490028
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.
USA models
Canada models
NOTE:
• When −3°C (−6°F) is corrected on the temperature setting set as 25°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-
celled.
