Danger!
Risk of injury due to hot and cold compo-
nents.
The heat pump may only be put into opera-
tion after all the cladding sections have
been fitted.
> Before starting up the unit, fit all of the
cladding parts.
> Fill out the start-up log before starting up the unit
(¬Ch.15).
The heat pump may only be started if all the points noted
there have been satisfied.
For the subsequent start-up, it is assumed that you know
how to operate the controller as described in the operating
instructions.
e
Danger!
Risk of electric shock!
> You must first fit all of the cladding parts
for the inner and outer unit before
switching on the voltage supply.
8.1 Carrying out the initial commissioning
As soon as the heat pump is supplied with power for the
first start-up, an internal self-test starts automatically and,
during this test, the heat pump tests itself and its con-
nected components to ensure that they work properly. In
doing so, the configuration of the sensors is checked, the
phase sequence of the 400 V voltage supply (phase
sequence) is checked and the sensors that are used are
checked to ensure that they work properly.
> Switch on the circuit breaker so that the heat pump is
supplied with power.
If the self-test is not successful, a fault message is shown in
the controller display (¬Ch.11).
The controller automatically checks the correct phase
sequence.
> If a fault message is displayed, swap two of the phases
with each other.
The heat pump starts and the software in the controller ini-
tialises:

8.1 Controller initialises
After a short time the controller is ready for operation and
detects that this is an initial commissioning. During the ini-

tion Assistant menu.
You can change all of the entries in the controller settings
at a later point.

You must also run the Installation Assistant
