connected indoor units has decreased.)
No signal can be sent to the indoor unit. (No communications from
outdoor unit to indoor unit)
There are multiple indoor units with the same address. (May also
be detected on the indoor unit)
The automatic indoor address operation has been performed
during automatic address setting of another line.
The automatic outdoor address operation has been performed
during indoor automatic address setting.
No data is received from the outdoor unit during automatic
address.
