6 Adjustment of heating operation

During commissioning, the heating characteristic curve is
adjusted to suit the building and local conditions. This heating
characteristic curve can be adjusted to individual temperature
requirements using the hotter/colder arrow buttons on the main
display.

For heating circuits 2/3, make this setting in the menu

The set heating characteristic curves can be lowered or raised on
a time-controlled basis. For example, in poorly insulated
buildings the heating characteristic curve can be lowered or

7 Domestic hot water heating

The heat pump manager automatically calculates the maximum
possible hot water temperature in heat pump operation. The
desired domestic hot water temperature can be set in the menu
"Settings – Domestic hot water – Hot water set temp".
TIP
As domestic hot water preparation takes place with high flow
temperatures and can therefore result in high energy costs, it is advisable
to adapt the domestic hot water preparation to the user behaviour. This
can be achieved with domestic hot water temperatures optimally adapted
to the requirements, with corresponding domestic hot water blocks and
large hysteresis.
Hot water temperature - HP maximum
To attain the highest possible heat pump ratio during domestic
hot water preparation, the heat pump manager automatically
calculates the maximum hot water temperature in heat pump
operation based on the current heat source temperature. The
lower the heat source temperature (e.g. external temperature,
brine temperature), the higher the attainable hot water
temperature.

7.1 Shut-off times for domestic hot water preparation

Shut-off times for domestic water heating can also be
programmed in the menu item "Settings – Domestic hot water –
Domestic hot water block". Domestic hot water heating is carried
out with only a minimum temperature during this period.

7.2 Thermal disinfection

In the menu item "Settings – Domestic hot water – Therm.
disinfection", thermal disinfection up to a hot water temperature
of 85 °C can be carried out for bivalent systems or domestic hot

7.3 Circulation

The circulation pump control can be programmed in the menu
item "Settings – Domestic hot water circulation". A maximum of
two time periods can be defined. A maximum of two circulation
time periods can be assigned for each week day. Requests
which exceed this will be activated or deactivated at the end of
each day accordingly.

raised before the shut-off time to prevent significant cooling of
the heating surfaces.
If the raising and lowering operations overlap each other, the
raising operation has priority.

)
↵
For energy-efficient operation of the heat pump heating system, the
temperature level to be generated by the heat pump should be set as low
as possible.
In well insulated buildings, an even heating operation without lowering
times usually leads to reduced energy costs, as peaks with high flow
temperatures are avoided and the same level of comfort is achieved with
lower temperatures.
Shut-off times can be compensated with a raise which begins approx. one
hour before the shut-off time.
Domestic hot water preparation without a flange
heater
If the domestic hot water set temperature exceeds the maximum
hot water temperature attainable by the heat pump, domestic hot
water preparation is terminated as soon as the "HP maximum
temperature" is reached.
Domestic hot water preparation with flange heater
If the domestic hot water set temperature exceeds the maximum
hot water temperature attainable by the heat pump, domestic hot
water preparation is carried out by the integrated flange heater
above the "HP maximum temperature".
NOTE
Reheating with flange heater
After domestic hot water preparation with the heat pump, the water can
be heated to higher temperatures if the system is equipped with a flange
heater. Domestic hot water heating is not reactivated until the heat pump
temperature returns to below the HP maximum temperature. This ensures
that heat pump can provide basic heating.
If the cylinder is sufficiently large, we recommend heating or
reheating domestic hot water during the night to take advantage
of favourable low tariff periods.
water cylinders with an integrated flange heater. Thermal
disinfection can be carried out for each week day. The start time
is selectable.
TIP
A circulation pipe is a major energy consumer. To save on energy costs,
circulation should not be used. If circulation cannot be avoided, however,
it is advisable to adapt the time window to the optimal conditions. It is
best to let the circulation run for a specific period via an impulse. This
function is also possible with the heat pump manager.
