VRV IV compressor unit for indoor installation
4P499900-1B – 2021.12
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.
7‑LEDs display – Mode 1 (H1P flashing)

Value / Description
[1‑5]
Shows the total number of
connected units (heat exchanger
unit + indoor units).
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).
[1‑14]
Shows the latest 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
"19.1 Solving problems based on
error codes"
38], 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
information about the malfunction
code, press BS2 up to 3 times.

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 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.
[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 compressor
unit.
▪ The first method is to enable a forced power
