Indoor/Outdoor communication
circuit error
(Detected at outdoor side)
Duplicated indoor addresses
1. Indoor/outdoor communication end terminal
resistance setup error
2. Indoor/outdoor communication connection error
Indoor addresses are duplicated.
Is setup of end
terminal resistance 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
shortcircuited?
Is connection of
inter-unit wire between
indoor and outdoor
correct?
Is there no error on
power wire to outdoor
unit?
Is there noise source?
Is F400 (fuse) on I/F P.C.
board opened?
Correct setup of end terminal
resistance.
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

Replace
I/F P.C. board failure
* 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.
