Note
The appliance user can set the appliance parameters de-
scribed in these operating instructions.
The remaining appliance parameters are to be found in
the commissioning instructions for the appliance.
 Ask your qualified contractor to set the remaining
appliance parameters.
 Make a note of the standard settings.
Note

5.8 Adjusting the heating circuit
Material losses
Bear in mind that radiator heating systems require dif-
ferent temperatures than area heating systems.
Material losses
For buildings with an area heating system, ensure that
the flow temperature is set correctly. Observe the infor-
mation in the area heating design documentation.
Note
Please note that the effect of the changes will be delayed.
Note
The device allows you to support a direct heating circuit
and a heating circuit with mixer.
To set up two to five additional heating circuits with mixer
in the heating system, you will need the extension mod-
ule available as an accessory.
Note
In order to access this menu, at least one heating cir-
cuit must be activated in the "Settings"/ "Mixing valves"
menu.
 Ask your qualified contractor to activate the func-
tion.

Adjusting the heating curve
Note
The heating curve is set according to the local building
conditions and your personal requirements. The device
uses the curve to calculate the required flow temperature
of the heating system.
Changes to the heating curve will influence the energy
efficiency of the heating system.
 Note the set values before making any changes.
 Do not change any values if you do not know the
possible effects of these changes.
Note
If you unable to adjust the heating curve, your system is
running in Fixed value operation.
 Have your qualified contractor switch off the "Fixed
value operation" function in the heating settings.
Use the heating curve to adjust the flow temperatures at specified
outside temperatures.
You can adjust the heating curve either as a whole or only indi-
vidual curve points.
