Shows the status of power consumption limitation operation.
Power consumption limitation reduces the power consumption of the
unit compared to nominal operating conditions.

0 Unit is currently not operating under power
consumption limitations.
1 Unit is currently operating under power
consumption limitation.
Power consumption limitation can be set in mode 2. There are two
methods to activate power consumption limitation of the outside 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 outside units (in case of
multiple module system).
It can be convenient to check if the total number of outside units
which are installed matches the total number of outside units which
are recognized by the system. In case there is a mismatch, it is
recommended to check the communication wiring path between
outside and outside units (Q1/Q2 communication line).

Shows:
▪ [1-17]: The latest malfunction code.
▪ [1-18]: The 2nd last malfunction code.
▪ [1-19]: 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
"10.2 Solving problems based on error codes" on page 45, where
most relevant malfunction codes are explained. Detailed information
about malfunction codes can be consulted in the service manual of
this unit.
