7.4.2 Mounting the outside temperature
sensor
The temperature sensor must be mounted in such a way that all
weather conditions are taken into consideration and the meas-
ured value is not falsified.
 On the external wall of a heated room used as living space,
if possible on the north or north-west side of the building
 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, ex-
ternal 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 in-
cluded 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 (ap-
ply 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 domestic hot water cylinder. A compact system is used
to simplify the installation process, so that a lot of different com-
ponents do not have to be installed individually. Further informa-
tion can be found in the relevant installation instructions.
Compact manifold
The return sensor can remain in the heat pump, or should be in-
stalled in the immersion sleeve. The remaining empty space be-
tween the sensor and the immersion sleeve must be filled com-
pletely with heat transfer compound.
Dual differential pressureless manifold
In order for the heating circuit pumps of the generator and con-
sumer circuits to supply the flow to the return sensor, this must
be installed in the immersion sleeve of the dual differential pres-
sureless manifold.
