Start-UP
8.1 General Information
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 established as
described in Chapter 6.
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 ventilator 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 controller's
operating instructions.
Ensure the condensate outflow functions.
Both the accessories pack in the switch box and that which
is located under the ventilator must be removed.

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
18 °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 25 °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 20 °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 18° C is maintained, the heat pump start-up
is complete.
ATTENTION!
Operating the heat pump at low system temperatures may
cause the heat pump to break down completely. After a
prolonged power failure, the commissioning procedure
detailed above must be followed.
8)
Clip the end caps (white) included in the accessories pack
in the screw holes on the sheet cover. Clip the black end
caps in the bottom holes on the frame parts or the base
plate.
