shows whether the unit you check is a master, slave 1 or slave 2 unit.
No indication: undefined situation
0: outdoor unit is master unit
1: outdoor unit is slave 1 unit
2: outdoor unit is slave 2 unit
Master, slave 1 and slave 2 indications are relevant in multiple outdoor unit
system configurations. The allocation of which outdoor unit is master, slave 1
or slave 2 are decided by the unit's logic.
The master unit should be used to input field settings in mode 2.
shows the status of low night noise operation.
1: unit is currently operating under low noise restrictions
0: unit is currently not operating under low noise restrictions
Night-time low noise operation reduces the sound generated by the unit
compared to nominal operating conditions.
Night-time low noise operation can be set in mode 2. There are two methods
to activate night-time low noise operation of the outdoor unit system.
The first method is to enable an automatic night-time low noise operation
during night time by field setting. The unit will operate at the selected low
noise level during the selected time frames.
The second method is to enable night-time low noise operation based on an
external input. For this operation an optional accessory is required.
shows the status of power consumption limitation operation.
1: unit is currently operating under power consumption limitation
0: unit is currently not operating under power consumption limitations
Power consumption limitation reduces the power consumption of the unit
compared to nominal operating conditions.
Power consumption limitation can be set in mode 2.
There are two methods to activate power consumption limitation of the
outdoor unit system.
The first method is to enable a forced power consumption limitation by field
setting. The unit will always operate at the selected power consumption
limitation.
The second method is to enable power consumption limitation based on an
external input. For this operation an optional accessory is required.

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).
