When address setup has finished in all the lines, turn off
SW30-2 on the interface P.C. boards of the header units
of the lines connected to the identical central control
except a line with least address marker.
(The end terminal resistances of the wires in the central
control system of indoor/outdoor are unified.)
Connect the relay connector between [U1U2] and [U3U4]
of the header unit for each refrigerant line.
Then set up the central control address.
(For the central control address setup, refer to the Instal-
lation manual of the central control devices.)
