In mode 1 (and in default situation) you can read out some
information.
7‑segments display – Mode 1
You can read out the following information:
Setting
Value / Description
[1‑1]
Shows the status
of low noise
operation.
0
Unit is currently not operating under low
noise restrictions.
1
Unit is currently operating under low
noise restrictions.
Low noise operation reduces the sound
generated by the unit compared to nominal
operating conditions.
Low noise operation can be set in mode 2.
There are two methods to activate low noise
operation of the outdoor unit system.
▪ The first method is to enable an automatic 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 low noise
operation based on an external input. For this
operation an optional accessory is required.
[1‑2]
Shows the status
of power
consumption
limitation
operation.
0
Unit is currently not operating under
power consumption limitations.
1
Unit is currently operating under power
consumption limitation.
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.

position.
For more information, see setting [2‑9].
[1‑10]
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 recognised 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).
