Address setup procedure 2
1. Using SW13 and 14 on the interface P.C. board of the header
outdoor unit in each system, set up the line (system) address
for each system.
(At shipment from factory: Set to Address 1)
Note) Be careful not to duplicate with other refrigerant system.

: Is not used for setup of line address. (Do not change setup.)
2. Check that the relay connectors between [U1U2] and
[U3U4] terminals are disconnected in all the header
outdoor units to which the central control is connected.
(At shipment from factory: No connection of connector)
3. Turn on power of indoor/outdoor.
(In order of indoor → → → → → outdoor)
4. After approx. 1 minute, check that 7-segment display is
U.1.L08 (U.1. flash) on the interface P.C. board of the
header outdoor unit.
5. Push SW15 and start setup the automatic address.
(Max. 10 minutes for 1 refrigerant system
(Usually, approx. 5 minutes))
6. When the count Auto 1 → → → → → Auto 2 → → → → → Auto 3 is
displayed in 7-segment display section, and it changes
from
U. 1. - - - (U. 1. flash) to U. 1. - - - (U. 1. light) , the
setup finished.
7. Procedure 4. to 6. are repeated in other refrigerant
systems.
8. How to set up terminator resistor (SW30)
When all the address setups have finished in the same
refrigerant system, put the terminator resistor (SW30)
in the same central control line into one.
• Remain only SW30-2 of the header outdoor unit with
the least line address number as it is ON.
(With terminator resistor)
• Set up SW30-2 of the other header outdoor units to
OFF. (Without terminator resistor)
9. Connect the relay connector between [U1U2] and
[U3U4] of the header outdoor unit for each refrigerant
system.
