7 Commissioning
7.1 General
To ensure that commissioning is performed correctly, it should
only be carried out by an after-sales service technician author-
ised by the manufacturer.

NOTE
Personal protective equipment (protective goggles, safety
shoes and gloves where necessary) must be used when work-
ing on the device. Components with plastic parts must be pro-
tected from impact (e.g. from tools) to prevent damage to
these components.
7.2 Preparation
The following items must be checked prior to commissioning:

All of the indoor unit connections must be installed.
 All of the outdoor unit connections must be installed.

The domestic hot water cylinder must be completely filled
and the domestic hot water feed open.

All valves which 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 settings of the master unit must be adapted to the
heating system in accordance with the operating instruc-
tions.

The heating water circuit and the buffer tank must be com-
pletely filled and purged.

Ensure that the condensate drain functions properly.
 The outflow from the heating water pressure relief valve
must also function correctly.
 The system must be completely filled with refrigerant and
the shut-off devices completely open.
7.3 Procedure
The heat pump is commissioned using the master unit or a
smart device paired with the pump. See the “Operation” manual
for instructions on operation, adjustment and set-up.
At heating water temperatures under 7 °C, commissioning is
not possible. The water in the buffer tank must be heated with
the 2nd heat generator to at least 20 °C.
To ensure problem-free commissioning, the following proce-
dure is to be implemented:
1) Close all consumer circuits.
2) Ensure that the heat pump has the correct water flow.
3) Wait until a return temperature of at least 25 °C has been
reached.
4) Now slowly reopen the heating circuit valves in succession
so that the heating water flow rate is constantly raised by
slightly opening the respective heating circuit. The heat-
ing water temperature in the buffer tank must not be al-
lowed to drop below 20 °C during this process. This en-
sures that the heat pump can be defrosted at any time.
5) When all heating circuits are fully open and a return tem-
perature of at least 20 °C is maintained, the commissioning
is complete.

ATTENTION!
Operating the heat pump at low system temperatures may
cause the heat pump to break down completely.
