3.2.3
Installing the strap-on sensor
It is only necessary to mount the strap-on sensors if they are
included in the scope of supply of the heat pump but have not yet
been installed.
The strap-on sensors can be fitted as pipe-mounted sensors or
installed in the immersion sleeve of the compact manifold.
Remove paint, rust and scale from heating pipe.
Coat the cleaned surface with heat transfer compound
(apply sparingly).
Attach the sensor with a hose clip (tighten firmly, as loose
sensors can cause malfunctions) and thermally insulate.
3.2.4
Hydraulic distribution system
The compact manifold and the dual differential pressureless
manifold function as an interface between the heat pump, the
heating distribution system, the buffer tank and, in some cases,
even the domestic hot water cylinder. A compact system is used
to simplify the installation process, so that a lot of different
components do not have to be installed individually. Further
information can be found in the relevant installation instructions.
Compact manifold
The return sensor can remain in the heat pump. Depending on
the integration, the demand sensor R2.2 may have to be installed
in the immersion sleeve. The empty space still present between
the sensor and the immersion sleeve must be filled completely
with heat transfer compound.
Dual differential pressureless manifold
In order for the heating circuit pumps of the generator and
consumer circuits to supply the flow to the demand sensor R2.2,
the demand sensor must be installed in the immersion sleeve of
the dual differential pressureless manifold.
