–
The flow sensor

must be installed upstream of
the circulation pump when viewed in the direction
of flow.
–
The calming section

before and after the flow sen-
sor must not be removed.

Connect the primary circuit circulation pump elec-
trically
►
Connect the flow sensor electrically
6.5 Connect heating circuit
There are two options for connecting the heating circuit
line to the heat pump:
–
Inlet from the heat pump
bottom
, (from the con-
crete foundation) with the
connection set bottom
–
Inlet from the heat pump
bottom
, (from the con-
crete foundation) with the
connection set bottom
Both solutions are described in detail below.
!
CAUTION
- Due to the oscillating bearing of
the heat pump unit, the connection of the hea-
ting circuit must not be carried out as a rigid
connection.
!
CAUTION
- The connection of the heating cir-
cuit must not be carried out with stainless steel
corrugated pipes (material not suitable).
