Split packaged air-cooled water chiller
4P508020-1A – 2018.01
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.
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
Fan high static pressure setting.
In order to increase the static pressure the outdoor unit fan is
delivering, this setting should be activated.
(default)
Deactivated.
Activated.
Automatic low noise setting and level during night time.
By changing this setting, you activate the automatic low noise
operation function of the unit and define the level of operation.
Depending on the chosen level, the noise level will be lowered.
(default)
Deactivated
Level 1
Level 3<Level 2<Level 1
Level 2
Level 3
Low noise operation level via the external control adaptor.
If the system needs to be running under low noise operation
conditions when an external signal is sent to the unit, this setting
defines the level of low noise that will be applied.
This setting will only be effective when the optional external control
adaptor (DTA104A62) is installed and setting [2‑12] was activated.
Level 1
Level 3<Level 2<Level 1

Level 2
Level 3
Power consumption limitation level via the external control adaptor
(DTA104A62)
If the system needs to be running under power consumption
limitation conditions when an external signal is sent to the unit, this
setting defines the level power consumption limitation that will be
applied. The level is according to the table.
Level 1
Level 3<Level 2<Level 1
(default)
Level 2
Level 3
Enable the low noise function and/or power consumption limitation
via the external control adaptor (DTA104A62).
If the system needs to be running under low noise operation or
under power consumption limitation conditions when an external
signal is sent to the unit, this setting should be changed. This
setting will only be effective when the optional external control
adaptor (DTA104A62) is installed in the indoor unit.
(default)
Deactivated.
Activated.
