Mode 1 (and default situation): Monitoring
settings
In mode 1 (and in default situation) you can read out some
information.
7‑LEDs display – Default situation (H1P OFF)
You can read out the following information:
Value / Description
H6P
Shows the status of low noise operation.
OFF
Unit is currently not operating under low noise
restrictions.
ON
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.
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)
You can read out the following information:
Setting
(
)
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).
