(monitoring
settings)
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
(field settings)
Mode2 is used to change the field settings of
the system. Consulting the current field setting
value and changing the current field setting

In general, normal operation can be resumed
without special intervention after changing field
settings.
Some field settings are used for special

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.
