REQUIREMENT
• When 2 or more refrigerant lines are controlled as a group, be sure to turn on all the indoor units in the
group before setting addresses.
• If you set the unit addresses of each line separately, each line's header indoor unit is set separately. In that
case, the Code No. "L03" (Indoor header unit overlap) is indicated as running starts. Change the group
address to make one unit the header unit using wired remote controller.
