Step 1
Push
SET
,
CL
and
TEST
buttons on the remote controller simultaneously for more than 4 seconds.
∗
In the group control operation, the unit No. displayed for the first time is the header unit No.
At this time, the CODE No. (DN) shows “
”. Also, the fan of the indoor unit selected starts its operation
and the swing operation starts if it has the louvers.
(The unit No. “
” is displayed if the auto-address setting mode is interrupted in [2] step 2 a))
Step 2
Every time when
UNIT LOUVER
button is pushed, the indoor unit No. in the group control operation are displayed
in order.
