1 Supply to heating circuit / domestic hot water
tank
2 Return sensor on hydraulic module
3 Supply from heat pump
4 Return to heat pump
Fasten return flow sensor (2) to the return (heat-
conducting pipe) to the heat pump (4) using cable ties
and thermal compound.
Hydraulic integration documents
The electrical connection between the heat pump and
hydraulic module is implemented via EVS or EVS8
(accessories). In dual variants, the lines (8 m) and
plugs are included in the scope of delivery.
The hydraulic module is connected on site to the sub-
distribution according to the following scheme:
5
1 Heat pump
2 Load Compressor
3 Bus (shielded)
4 Control voltage (for dual heat pump only)
5 Hydraulic module
6 Heating element load line
7 Control voltage
8 Load Compressor
9 Sub-distribution

NOTE
The control panel of the heating and heat
pump controller can be connected to a
computer or network using a suitable network
cable, enabling the heating and heat pump
controller to be controlled remotely from
there.
If such a connection is required, then install
a shielded network cable (category 6,
with RJ45 connector) during the electrical
connection work and connect it parallel to the
existing control cable of the heating and heat
pump controller.
NOTE
In units with integrated electric heating
element, the electric heating element is
connected at 9 kW (6kW) in the factory.
At contactor Q, it is possible to select 6 kW
(4kW) = 2 phase operation. Disconnect
Q5/6 for this. Or 3kW (2kW) = 1 phase
operation. Disconnect Q5/6 and Q5/4 for this.
The values in brackets are for the 6kW
heating element. Disconnected cables must
be furnished with screw terminals. Only the
phases cited above may be disconnected
(safety temperature limiter).
