# Code
[A.3.1.3.1] [9-09] Heating: required temperature
difference between entering and
leaving water.
In
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
difference is required for the good
operation of the heat emitters in cooling
mode.
Leaving water temperature: Modulation
# Code
[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
required capacity and results in less
start/stop cycles of the heat pump
and more economic operation.

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).

4 Configuration
Description
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.
Description
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.
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
equals which temperature under [A.
4.3.2.1]~[A.4.3.2.6]:
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.
