5 Operating Modes
6 different operating modes can be selected using the button
(Modus). There is a time delay between switching modes. The
operating mode can be changed each time the button is pressed
in the order shown below.
NOTE
Heat pump operation block
The heat pump is blocked in the 2nd heat generator operating mode.
Heating operation and DHW preparation in mono energy systems is
carried out using electric heating elements. In the case of bivalent
systems, the 2nd heat generator is used.
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 Warmer/colder arrow buttons on the main display.
Increase the temperature with the ⇑button. The indicator bar in
the last line will move to the right.
Decrease the temperature with the ⇓button. The indicator bar in
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
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.
COOLING
Selectable only when the
cooling controller is
connected
(see Installation and
Start-up)
The system operates in cooling operation. The individual control functions are active. This
operating mode can only be activated if a cooling controller is connected to the heat pump
manager and the cooling function has been enabled in the preconfiguration.
SUMMER Only domestic hot water and swimming pool water are heated up in the SUMMER operating
mode. Space heating is not activated. Antifreeze (frost protection) is ensured.
AUTO The heat pump operates in automatic operation. Programmed lowering times, raising times and
shut-off-times for heating and DHW heating are activated automatically. DHW heating, heating
and swimming pool heating are activated according to priority. The heat pump and the 2nd heat
generator are switched on or off as required.
VACATION
(lower operation)
A lowering of the heating characteristic curves and a hot water block are activated in the
VACATION operating mode. Both functions are independent of any relevant timings, but the
lower values set for these functions still apply. The duration of the VACATION operating mode
can be set in the menu “1 Settings – Operation – Vacation mode”. After this time period has
elapsed, the system switches automatically back to automatic operation again.
PARTY
(daytime operation)
A programmed lowering of the heating characteristic curves is overridden in the PARTY operating
mode. The duration of the PARTY operating mode can be set in the menu “1 Settings –
Operation – Party mode”. After this time period has elapsed, the system switches automatically
back to automatic operation again.
2nd heat generator
(HG2)
The heat pump is switched off in this operating mode and the entire heat supply is provided by
the 2nd heat generator (HG2). This is the immersion heater in mono energy systems. In bivalent
systems it is the oil or gas heating. Time programs and heating curve settings remain active.

7.2
7 DHW Heating
The heat pump manager automatically calculates the maximum
possible hot water temperature in heat pump operation. The
desired 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.
Hot water cylinder without flange heater
If the hot water set temperature exceeds the maximum attainable
hot water temperature in heat pump operation, DHW 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.
7.1 Shut-Off times for DHW Preparation
In addition to 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“. No DHW heating is
carried out during this period.
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 utilized.
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
systems with hot water cylinders and integral flange heaters. The
thermal disinfection can be carried out for each day of the week.
The start time is selectable.

9.2 Fault Messages
Fault Messages on the display fall into three broad categories:
Heat pump fault
Plant fault and
Sensor fault
You only need to inform your after-sales service if there is a heat
pump fault (HP fault). Make a note of the error message and the
software version displayed in the operating data. After rectifying
the problem, press the Esc button to acknowledge the fault.
The following messages may appear on the display.
NOTE
Plant fault
In mono energy systems, the minimum return set temperature is set if a
heat pump or plant fault occurs. Antifreeze (frost protection) is ensured.
By manually switching to the 2nd heat generator operating mode, the
building is heated exclusively using the immersion heater.
