mer

INFOID:0000000003884687

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. 

HOW TO SET

Using CONSULT-III, perform “TEMP SET CORRECT” on “WORK SUPPORT” of HVAC. 

NOTE:
• When the temperature setting is set to 25.0
