Circulation pumps
Important
Always note the unit model.
do not use controlled circulation pumps.
Heating circuit and domestic hot water
circulation pumps must be designed as constant
speed pumps.
note:
The minimum heating water, heat source flow
rate must be ensured!
note:
When dimensioning the circulation pump of the
heat sources the viscosity of the brine liquid
must be taken into account!
note:
A motor protection switch for the pump is
integrated in the heat pump!
An external motor protection switch must
be installed if a stronger groundwater pump is
required.

Electrics.
For details of the minimum heating circuit/heat
source flow rate, refer to the “Technical data/
scope of delivery overview, “Heating circuit”
“heat source” section for the respective type.
Domestic water heating
domestic water heating with the heat pump requires an
additional heating water circuit (parallel) to the heating
circuit. When connecting, make sure that the domestic
hot water charge is not fed through the buffer tank of
the heating circuit.
“Hydraulic connection” documents.
Buffer tank
The hydraulic integration of the heat pump requires a
buffer tank in the heating circuit. The necessary volume
of the buffer tank is given by the following formula:
v
buffer tank
=
minimum throughput heating circuit flow rate / hour
