6 Configuration
Value / Description
H7P Shows the status of power consumption limitation operation.
OFF
Unit is currently not operating under power
consumption limitations.
ON
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.

Value / Description
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).
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
"8.1 Solving problems based on
error codes" on page 28, where
most relevant malfunction codes
are explained. Detailed
information about malfunction
codes can be consulted in the
service manual of this unit.
To obtain more detailed

operation.
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.
