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 compressor unit and heat
exchanger unit.
▪ 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.

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 compressor
unit.
▪ 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.

It can be convenient to check if the total number
of units which are installed (heat exchanger unit
+ indoor units) match the total number of units
which are recognised by the system. In case
there is a mismatch, it is advised to check the
communication wiring path between compressor
unit and heat exchanger unit, and between
compressor unit and indoor units (F1/F2
communication line).
