Function description
Start the heat pump via the external temperature
sensor (B9). This works directly in the heating
circulation.
Depending upon the ambient temperature, the heat
pump is switched on and off via the return flow
temperature (B71). The machine has a starting delay in
order to prevent wobbling.
The integrated electric heating insert (K25) can be
used as emergency heating.
The condenser pump (Q9) is in operation during the
entire heating period.

Function description
Start the heat pump via the external temperature sensor
(B9). This works directly in the heating circulation. A buffer
storage is integrated in the return flow.
Depending upon the ambient temperature, the heat
pump is switched on and off via the return flow
temperature (B71). The machine has a starting delay in
order to prevent wobbling.
The integrated electric heating insert (K25) can be used
as emergency heating.
The condenser pump (Q9) is in operation during the entire
heating period.
The size of the built-in expansion vessel (EV) must be
controlled and depending upon the water content must
be supplemented with an external vessel.

Function description
Start the heat pump via the external temperature sensor (B9).
This works directly in the heating circulation.
Depending upon the ambient temperature, the heat pump is
switched on and off via the return flow temperature (B71). The
machine has a starting delay in order to prevent wobbling.
The integrated electric heating insert (K25) can be used as
emergency heating.
The condenser pump (Q9) is in operation during the entire
heating period.
DHW is charged according to the time program via the
temperature sensor (B3), the deflector valve (Q3) is thus
switched. The electrical insert (K6) in the DHW storage is
controlled by the heat pump controller.

Function description
As soon as the swimming pool pump is put into operation,
the heat pump for the swimming pool charging is
switched-on from outside by the swimming pool controller
via input H1.
The swimming pool pump is controlled by the swimming
pool controller.
The swimming pool temperature (control temperature) is
monitored with the swimming pool sensor (B13).
Attention:
The heat pump must not be enabled unless there is a flow
through the heat exchanger.
When operating the swimming pool charging with/without
buffer storage, the total heat pump output (B0/W35 or
W10/W35) must be accepted by the swimming pool heat
exchanger.
The swimming pool must be taken into consideration when
designing the soil sensor.

Free cooling, heating circuit/cooling circuit directly without buffer storage
Note: This additional sheet contains additional connection instructions for the electrical installation.
Function description
For passive cooling (free cooling), cooling is done
without operating the cryogenic unit. Heat is directly
returned to the connected source (soil sensor or
ground water).
The heat pump controller runs a cooling curve via the
ambient temperature (B9), this is controlled with the
connected mixer (Y1/Y2) and the flow temperature
(B1). For cooling requirement, the source circuit is
controlled by means of a deflector valve (Y21) via the
plate heat exchanger (PHE). For heating requirement,
the deflector valve is reset and the mixer is shut.
For available room thermostat valves, these must
be adaptable for the cooling as well as the
heating operation.

Free cooling, heating circuit/cooling circuit indirectly with buffer storage or combination storage
Note: This additional sheet contains additional connection instructions for the electrical installation.
Function description
For passive cooling (free cooling), cooling is done
without operating the cryogenic unit. Heat is directly
returned to the connected source (soil sensor or
ground water).
The heat pump controller runs a cooling curve via the
ambient temperature (B9), this is controlled with the
connected mixer (Y1/Y2) and the flow temperature
(B1). For cooling requirement, the source circuit is
controlled by means of a deflector valve (Y21) on both
sides via the plate heat exchanger (PHE).
For heating requirement, the deflector valve is set back
to the heating position. For a set discharge circuit
control, the mixing valve Y1/Y2 is integrated in the
controller.
For available room thermostat valves, these must be
adaptable for the cooling as well as the heating
operation.

Function description
The heat pumps are operated via the external sensor B9. This
works on the buffer storage.
Depending upon the ambient temperature, the heat pumps
are switched on and off via the
temperature sensor B4 or B41. The machine has a starting
delay in order to prevent wobbling.
If the common flow temperature B10 is not attained, based on
release limit, another heat producer is switched on
additionally.
If the currently switched on heat producer exceeds the
requested power requirement, the producer switches off with
the highest priority.
System-specific testing/adaptation:
- Primary side (brine, water intake), discharge circuit control
- Storage size depending upon the performance of the heat
producer
- Hydraulic integration
- Shut-off devices, control valves, check valves as per
requirement
- Design of expansion system
- Fit adequate dipping sleeves for sensors, thermostats
and thermometer
- Observe structural conditions (insertion, installation, ...)

Function description
The first slave machine is used for warm water charging,
wherein, even the appropriate components are connected. At
active charging, the heat pump is isolated hydraulically from
the system and is not available for the heating operation.
After complete charging, the heat pump is again available for
the heating operation.
The control regulates the domestic water temperature as per
time schedule program at the desired setpoint. Boiler charging
is started via drinking water sensor (B3). Once the sensor
(B31) attains the desired temperature, charging is stopped.
System-specific testing/adaptation:
- Primary side (brine, water intake), discharge circuit control
- Storage size depending upon the performance of the heat
producer
- Hydraulic integration
- Shut-off devices, control valves, check valves as per
requirement
- Design of expansion system
- Fit adequate dipping sleeves for sensors, thermostats
and thermometer
- Observe structural conditions (insertion, installation, ...)
