indoor units to be controlled
from the MA remote controller,
assign the smallest address to
the main indoor unit in the
group.
ΠIn an R2 or WR2 system with a
sub BC controller, make the
settings for the indoor units in
the following order.
(i) Indoor unit to be connected
to the main BC controller
(ii) Indoor unit to be connected
to sub BC controller 1
(iii) Indoor unit to be connected
to sub BC controller 2
Make the settings for the indoor
units in the way that the formula
"(i) < (ii) < (iii)" is true.
ΠEnter the indoor unit
group settings on the
system controller
(MELANS).
ΠPort number setting is
