Mode 1 can be used to monitor the current situation of
the outdoor unit. Some field setting contents can be
monitored as well.
Mode 2 is used to change the field settings of the
system. Consulting the current field setting value and
changing the current field setting value is possible.
In general, normal operation can be resumed without
special intervention after changing field settings.
Some field settings are used for special operation (e.g., 1
time operation, recovery/vacuuming setting, manual
adding refrigerant setting, etc.). In such a case, it is
required to abort the special operation before normal
operation can restart. It will be indicated in below
explanations.
