7.5.4 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 in-
formation 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.

7.6 Electrical connection

7.6.1 General
All electrical installation 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 to N1-J20; N1-J23 to N1-J26 and the terminal
strips X3. If, due to a wiring error, the line voltage is mistakenly
connected to these terminals, the heat pump manager will be
destroyed.
NOTE
For installation work on the switch box, ensure that the mains
cable and signal cables are inserted separately into the switch
box. The specially arranged switch box inlets must be used for
this purpose (see Fig.7.3 on pag. 8).
The mains cables and signal cables must also always be laid
separately in the switch box during wiring work.
