Commissioning
When the hydraulic system is filled and ready for op-
eration, connect the controller to the mains.
The controller runs an initialisation phase in which
the directional pad flashes red.
When the controller is commissioned for the first
time or when it is reset (see page 32), it will run
a commissioning menu after the initialisation phase.
The commissioning menu leads the user through the
most important adjustment channels needed for op-
erating the system. For navigating in the commission-
ing menu, see page 8.
2.1
Step-by-step parameterisation
a. Running the commissioning menu
The commissioning menu is run after the first con-
nection and after every reset (see page 32). It will
request the following basic adjustments:
• Menu language
• Time
• Date
• Circulation
• Afterheating
• Disinfection
When the last item
Save
at the end of the commis-
sioning menu is selected, a security enquiry appears.
If the safety enquiry is confirmed, the adjustments
are saved. For further information about the com-
missioning menu see page 13.

b. Activating the main functions
Adjustments for the main functions

can be made. Main
functions that have not been activated in the com-
missioning menu can now be activated here.
Free relays can be allocated to main functions which
require a relay. The controller always suggests the nu-
merically smallest free relay.
Sensors can be allocated to more than one function.
For further information about the main functions see
page 17.

c. Activating additional functions
Only after the required main functions have been ac-
tivated and adjusted, should the additional functions
be activated.
Any free relay can be allocated to any of the main
functions. The controller always suggests the numeri-
cally smallest free relay.
Sensors can be allocated to more than one function.
For further information about the additional func-
tions see page 28.
