The temperature sensors to be connected to the heat pump
manager must correspond to the sensor characteristic curve
illustrated in Fig.7.2 on pag. 9. The only exception is the external
temperature sensor included in the scope of supply of the heat
pump (see Fig.7.3 on pag. 9)

7.4.2 Mounting the external temperature
sensor
The temperature sensor must be mounted in such a way that all
weather conditions are taken into consideration and the
measured value is not falsified.
 Mount on the external wall on the north or north-west side
where possible
Do not install in a "sheltered position" (e.g. in a wall niche or

under a balcony)
Not in the vicinity of windows, doors, exhaust air vents,

external lighting or heat pumps
 Not to be exposed to direct sunlight at any time of year

7.4.3 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.
Mounting as a pipe-mounted sensor
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.

7.4.4 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 hot water cylinder. A compact system is used to
55 60
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, or should be
installed in the immersion sleeve. The remaining empty space
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 return sensor, this
must be installed in the immersion sleeve of the dual differential
pressureless manifold.
