setting of indoor unit displayed the communication error among indoor units is 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
At this time, is the voltage
between lines spherical wave over
DC ±0.7V ?
YES
If address is no fault,
to exchange the indoor unit PCB after
communication line check.
After connecting again the communication line
connecting from outdoor unit to indoor unit,
to check this communication is reverse or not,
and if there is no fault, to find the indoor unit
preventing communication through connecting
indoor units each by each, and then
exchange the indoor unit PCB after line check
