17.2.1 Mode 1 and Monitoring mode
Mode 1 can be used to define some setting parameters. Monitor
mode can monitor the current situation of the outdoor unit / system.
Some field setting contents can be monitored as well.
Below the monitor mode parameters and settings in mode 1 are
explained.
Monitor mode (H1P is blinking)
[M-5]= shows the total number of connected indoor units
It can be convenient to check if the total number of
indoor units which are installed match the total number
of indoor units which are recognized by the system. In
case there is a mismatch, it is advised to check the
communication wiring path between outdoor and indoor
units (F1/F2 communication line).
[M-6]= shows the total number of BS boxes connected to the
outdoor unit (only in case of system use as heat
recovery)
[M-8]= shows the total number of connected outdoor units (in
case of multi outdoor unit system)
It can be convenient to check if the total number of
outdoor units which are installed matches the total
number of outdoor units which are recognized by the
system. In case there is a mismatch, it is advised to
check the communication wiring path between outdoor
and outdoor units (Q1/Q2 communication line).
[M-14]= shows the latest malfunction code
[M-15]= shows the 2nd last malfunction code
[M-16]= shows the 3rd last malfunction code
When the latest malfunction codes were reset by
accident on an indoor unit user interface, they can be
checked again through this monitoring settings. For the
content or reason behind the malfunction code see
"18.2. Malfunction code list" on page
relevant malfunction codes are explained. Detailed
information about malfunction codes can be consulted

17.3. Mode 2

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., one time
operation for performing specific checks, recovery/vacuuming
setting, 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.
