7.3 Electrical connection
3 lines/cables must be routed to the heat pump in total:

A standard 5-core cable is used to connect the heat pump
to the power supply.
The cable must be provided on-site. The conductor cross
section is selected in accordance with the power con-
sumption of the heat pump (see attachment Device Infor-
mation) and the applicable VDE (EN) and VNB regulations.
An all-pole disconnecting device with a contact gap of at
least 3 mm (e.g. utility blocking contactor or power contac-
tor) must be installed in the heat pump power supply. A 3-
pole circuit breaker with joint tripping of all outer conduc-
tors (trip current in accordance with device information)
provides the short circuit protection taking into account
the layout of the internal wiring.
The relevant components in the heat pump contain an in-
ternal overload protection.
When connecting, ensure that the incoming supply has a
clockwise rotating field.
Phase sequence: L1, L2, L3.
CAUTION!
!!
Ensure that there is a clockwise rotating field: With incorrect
wiring the starting of the heat pump is prevented. A
corresponding warning is indicated on the display of the heat
pump manager (adjust wiring).
 The control voltage is supplied via the heat pump manager.
A 3-pole line must be laid for this in accordance with the
electrical documentation. Further information on the wir-
ing of the heat pump manager is available in the heat pump
manager operating instructions.

A shielded communication line (J-Y(ST)Y ..LG) (not in-
cluded in the scope of supply) connects the heat pump
manager with the refrigeration circuit control installed in
the heat pump. More detailed instructions can be found in
the heat pump manager operating instructions and in the
electrical documentation.
NOTE
ººººº
The communication cable is necessary for the function of
airto- water heat pumps in outdoor installation. It must be
shielded and laid separately from the mains cable.
7.3.1 Demand sensor connection
The demand sensor R2.2 (NTC 10) is included with the heat
pump manager. It must be installed depending on the hydrau-
lics used.
If a demand sensor is not connected, the second heat genera-
tor can not be controlled with the heat pump manager in the
event of an interruption in communication either.
NOTE
ººººº
The return sensor R2 installed in the heat pump is active when
the compressor is running and must not be disconnected.
8 Start-up
8.1 General
To ensure that start-up is performed correctly, it should only be
carried out by an after-sales service technician authorised by
the manufacturer. These measures can also include an addi-
tional warranty under certain conditions (see Warranty).
8.2 Preparation
The following items need to be checked prior to start-up:
 All of the heat pump connections must be installed as de-
scribed in chapter 7.
 All valves that could impair the proper flow of the heating
water in the heating circuit must be open.
 The air intake and air outlet paths must be clear.

The fan must turn in the direction indicated by the arrow.
 The settings of the heat pump manager must be adapted
to the heating system in accordance with the manager’s
operating instructions.

Ensure the condensate outflow functions properly.
8.3 Procedure
The heat pump is started up via the heat pump manager. Ad-
justments should be made in compliance with the instructions.
At hot water temperatures under 7 °C, start-up is not possible.
The water in the buffer tank must be heated to a minimum of
22 °C with the second heat generator.
To ensure a problem-free start-up, the following procedure is to
be implemented:
1) Close all consumer circuits.
2) Ensure that the heat pump has the correct water flow.
3) Use the manager to select the automatic operating mode.
4) In the special functions menu, start the "Start-up" program.
5) Wait until a return temperature of at least 29 °C has been
reached.
6) Now slowly reopen the heating circuit valves in succession
so that the heating water flow is constantly raised by
slightly opening the respective heating circuit. The heating
water temperature in the buffer tank must not be allowed
to drop below 24 °C during this process. This ensures that
the heat pump can be defrosted at any time.
7) When all heat circuits are fully open and a return tempera-
ture of at least 22 °C is maintained, the heat pump start-up
is complete.
CAUTION!
!!
Operating the heat pump at low system temperatures may
cause the heat pump to break down completely.
