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 meas-
ured 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, 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
(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 sim-
plify the installation process, so that a lot of different compo-
nents 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
pressureless manifold.

7.5 Electrical connection

7.5.1 General
All electrical connection work must be carried out by a trained
electrician or a specialist for the specified tasks in accordance
with the
installation and operating instructions,

country-specific installation regulations (e.g. VDE 0100),

technical connection conditions of the energy suppliers

and supply grid operators (e.g. TAB) and
 local conditions.
To ensure that the frost protection function of the heat pump
works properly, the heat pump manager must remain con-
nected to the power supply and the flow must be maintained
through the heat pump at all times.
The switching contacts of the output relay are interference-
suppressed. Therefore, depending on the internal resistance of
the measuring instrument, a voltage can also be measured
when the contacts are open. However, this will be much lower
than the line voltage.
Extra-low voltage is connected to controller terminals N1-J1 to
N1-J11; N1-J19; N1-J20; N1-J23 to N1-J26 and terminal strip
X3; X5.1. If, due to a wiring error, the line voltage is mistakenly
connected to these terminals, the heat pump manager will be
destroyed
7.5.2 Electrical installation
1) The supply electric cable for the output section of the heat
pump (up to 4-core) is fed from the electricity meter of the
heat pump via the utility blocking contactor (if required)
into the heat pump Connection of the mains cable to the
control panel of the heat pump via terminal X1: L1/L2/L3/
PE.
An all-pole disconnecting device with a contact gap of at
least 3 mm (e.g. utility blocking contactor or power contac-
tor) and an all-pole circuit breaker with common tripping
for all external conductors must be installed in the power
supply for the heat pump (tripping current and characteris-
tic in compliance with the device information).
