communication error among indoor units are
overlapped or not.
(If the indoor unit address is overlapped, the
communication error is occurred.)
- In this case, the communication error is
occurred to over two indoor units set
wrong.
No
When tracking, is there any
indoor answer from display part?
Yes
Measure the 2 lines of outdoor side
by scope after removing the
communication line connecting from
outdoor unit to indoor unit.
If address is not fault
exchange the indoor unit PCB after
communication line check.
At this time, is the voltage
between lines rectangular wave over DC±0.7V
like below figure?
No
Yes
Replace PCB after checking
the outdoor unit communication line
and connector
After connecting again the communication
line connecting from outdoor unit to indoor unit,
remove the communication
connector on indoor unit PCB, and find the
indoor unit preventing communication
through connecting the communication
connectors each by each, and then replace
the indoor unit PCB after line check.
