Indoor/Outdoor communication
circuit trouble
(Detected at outdoor side)
Duplicated indoor addresses
1. Indoor/outdoor communication terminator resistor
setup trouble
2. Indoor/outdoor communication connection trouble
Indoor addresses are duplicated.
Is setup of
terminator resistor of
outdoor unit normal?
Is wire connection to
communication line
normal?
Is not communication
line connected to the
different outdoor
unit?
Is indoor unit quantity
connected to outdoor
unit correct?
Is inter-unit wire
(U1, U2) between indoor
and outdoor short-
circuited?
Is connection of
inter-unit wire between
indoor and outdoor
correct?
Is there no trouble on
power wire to outdoor
unit?
Is there noise source?
Is F400 (fuse) on I/F P.C.
board opened?
Correct setup of terminator
resistor
Correct wire connection.
Correct communication line.
Set up indoor address again.
Correct communication line.
Correct power wire.
Turn on power to start operation.
Eliminate noise.
Outdoor I/F P.C. board failure
Replace
I/F P.C. board failure
However an emergent operation is
available by inserting connector to
be connected to CN01 to CN33.
* Check conduction with tester.
Correct short-circuit.
Using a wired remote controller (RBC-AMT32UL), check the setup CODE
No. (DN code) 12, 13, and 14.
When there is no address duplication, check to the following flowchart.
