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.
