6 Adjustment of Heating Operation

During start-up, 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.
Increase the temperature with the
the last line will move to the right.
Decrease the temperature with the
the last line will move to the left.
For heating circuits 2/3, make this setting in the "Heating circuit
2/ 3" 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 DHW 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".
Hot water temperature - HP maximum
To attain the highest possible heat pump ratio during DHW
preparation, the controller automatically calculates the maximum
possible 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.

If the hot water set temperature exceeds the maximum attainable
domestic hot water temperature in heat pump operation, DHW

7.1 Shut-off Times for DHW Preparation

Besides the hot water temperature, shut-off times for DHW
heating can also be programmed in the menu item "Settings –
Domestic hot water – 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.
Desinfection" it is possible to carry out a thermal disinfection
with hot water temperatures of up to 85 °C in bivalent systems or

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.
NOTE
Energy-efficient operation
For energy-efficient operation of the heat pump heating system, the
temperature level to be generated by the heat pump should be as low as
possible.
In well-insulated buildings, constant heating operation without lowering
times will normally result in lower energy costs. This is because power
peaks with high flow temperatures are avoided and the same degree of
comfort is attained at lower temperatures.
Shut-off times can be compensated for by a temperature rise that begins
1 hour before the shut-off time takes effect.
preparation is terminated once the so-called HP maximum
temperature is reached.
Hot water cylinder with flange heater
If the hot water set temperature exceeds the maximum attainable
hot water temperature in heat pump operation, DHW preparation
with the heat pump is terminated once the so-called HP
maximum temperature is reached, and the desired hot water
temperature is attained by reheating using the flange heater.
NOTE
Reheating with flange heater
After DHW preparation with the heat pump, the water can be further
heated to higher temperatures if the system is provided with a flange
heater. DHW heating does not take place again until the HP maximum
temperature is undershot. This ensures that basic heating can be carried
out by the heat pump.
If a sufficiently large cylinder is available, we recommend
carrying out DHW heating or reheating during the night-time
hours. This means that the more favourable low tariff periods
normally available can be utilised.
systems with hot water cylinders and integral flange heaters.
Thermal disinfection can be carried out for each day of the week.
