[In case of 29 refrigerant lines or less (Includes No. of refrigerant lines at Multi side if mixed)]
After the system power supply has been turned on, all the line addresses are allocated to “1” by automatic
address setup except group control. Therefore change setup of the line address using the wired remote con-
troller for each refrigerant line.

In case of group control including twin, triple, double twin system, the automatic address does not normally work.
Set the automatic address again from the wireless remote controller manually.
∗ For change/setup method by wired remote controller, refer to “Address Setup/Change Method”. (Page 21)
∗ Allocating different numeral value for each refrigerant line, set up the line address so that it does not overlap
with other address No. (When controlling collectively VRF type units mixed with digital inverter air conditioner
unit, set up numeral value which also differs from line address at VRF type air conditioner side.)
