ADDRESS SETUP
When address setup has finished in all the systems, turn
off SW30-2 on the interface P.C. boards of the lines
connected to the identical central control except a line
with least line address number.
(Terminator resistors of the wires in the central control
line of indoor/outdoor are unified.)
Connect the relay connector between [U1U2] and [U3U4]
terminals of the outdoor 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.)
