Integrate the hot water tank in the heat pump system
as shown in the hydraulic diagram for your system.
22 Electrical connection work
The following applies to all work to be done:
DANGER
Risk of fatal electric shock!
All electrical connection work must be
carried out by qualified electricians only.
Before opening the unit, disconnect the
system from the power supply - wait for
90 seconds = residual voltage at inverter -
and prevent it from being switched back on
again!
WARNING
Note and follow the relevant EN, VDE and/or
local safety regulations during installation
and when carrying out electrical work.
Comply with technical connection require-
ments of the responsible power supply
company (if required by the latter)!
NOTE
All live cables must be stripped before they
are laid in the cable duct of the switch box!
Power connection
1. If the unit is connected, open the lower facing
panels on the operating side.

“Installation”.
2. Open the unit's electrical switch box.

electrical switchbox
17 Pressure safety
Equip the heating circuit with a safety valve and
expansion vessel in accordance with local standards
and guidelines.
Also install filling and draining emptying devices, shut-
off devices and non-return valves in the heating circuit.
18 Circulation pump
The circulation pump is installed in the unit. Only one
PWM signal is available for the circulation pump,
therefore the domestic hot water supply must be
provided with the changeover valve via the BUP outlet.
Normally open = heating.
19 Buffer tank
The hydraulic integration of the heat pump
requires a buffer tank in the heating circuit. It
ensures a minimum running time for the heat
pump if the heating circuit valves are shut off.
Minimum volume of buffer tank 200 l
20 Water heating
Water heating with the heat pump requires another
heating water circuit in addition (parallel) to the heating
circuit. When integrating, make sure that the hot water
supply is not fed through the buffer tank of the heating
circuit.

21 Hot water tank
If the heat pump is to be used to heat water, you
must integrate special hot water tanks in the heat
pump system. Choose the storage volume so that the
required quantity of hot water is available even during
a power cut.
The heat exchanger surface of the hot water tank must
be dimensioned so that the heating capacity of the
heat pump is transferred with minimum temperature
drop. We offer a variety of hot water tanks for you to
choose from. They are optimally matched to your heat
pump.
