Heating: required temperature
difference between entering and
leaving water.
In case a minimum temperature
difference is required for the good
operation of the heat emitters in heating
mode.
[A.3.1.3.2]
[9-0A]
Cooling: required temperature
difference between entering and
leaving water.
In case a minimum temperature
difference is required for the good
operation of the heat emitters in cooling
mode.
Leaving water temperature: Modulation
#
Code
Description
[A.3.1.1.5]
[8-05]
Leaving water temperature modulation:
▪ 0 (No): Disabled
▪ 1 (Yes): Enabled. The leaving water
temperature is calculated according
to the difference between desired
and actual room temperature.
This allows better matching of the
heat pump capacity to actual
required capacity and results in less
start/stop cycles of the heat pump
and more economic operation.
Leaving water temperature: Emitter type

Reaction time of the system:
▪ 0: Quick. Example: Small water
volume and fan coils.
▪ 1: Slow. Example: Large water
volume, floor heating loops.
Depending on the system water volume
and the heat emitters type, the heat up
or cool down of a space can take
longer. This setting can compensate for
a slow or a quick heating/cooling
system by adjusting the unit capacity
during the heat up/cool down cycle.

#
Code
Description
[A.4.1]

Domestic hot water Setpoint mode:
▪ 0 (Reheat only): Only reheat operation
is allowed.
▪ 1 (Reheat + sched.): Same as 2, but
between the scheduled heatup cycles,
reheat operation is allowed.
▪ 2 (Scheduled only): The domestic hot
water tank can ONLY be heated
according to a schedule.
[A.4.3.1]
N/A
How has the tank temperature to be
displayed on the user interface?
▪ As temperature.
▪ As graphic: The temperature has to
displayed as available hot water for
x persons. If you choose this, you also
have to configure which number
equals which temperature under [A.
4.3.2.1]~[A.4.3.2.6]:
[A.4.5]
[6-0E]
The maximum temperature that users
can select for the domestic hot water.
You can use this setting to limit the
temperature at the hot water taps.
INFORMATION
It is recommended NOT to use the selection of ([6
‑
0D]=0,
[A.4.1] Domestic hot water Setpoint mode=Reheat only) in
case of a domestic hot water tank without internal booster
heater.
The risk of space heating (cooling) capacity shortage/
comfort problems is significant (in case of frequent
domestic hot water operation, frequent and long space
heating/cooling interruption will happen).
