Putting the heating circuits into operation
More or fewer heating circuit functions are available depending on the scope of
the selected solar functions.
The putting into operation of the heating circuit 1 as a mixed heating circuit will be
described by way of example.
Select the "Basic settings" menu.
Select the "Heating circuit" menu point.
Select the "Heating circuit 1" menu point.
Select the "Mixed" menu point.
The OK symbol will be displayed and will flash.
To confirm the entry, select
.
The value "Mixed" will be indicated for the "Heating circuit 1" menu point.
The heating circuit is thus activated as a mixed heating circuit. All related switching
outputs and sensor inputs are now assigned and will be actuated or evaluated
accordingly by the controller. Further details can be found in the document
Hydraulic
layouts
.
When you switch off the heating circuit (e.g. via the "Program/Operating
mode" menu point), the supply line setpoint value will be set to 11 °C
. When
you switch on the heating circuit again, the supply line setpoint value will be reset
without delay to the regular working value.

Screed heating
You can activate the function when all the relevant parameters have been set.
If you change any parameters subsequently, you must restart the function for the
changes to take effect.
Here you can start a defined program for heating and cooling the screed.
You can choose between all mixed heating circuits.
All other heating circuit functions are deactivated during screed heating.
When the heating and cooling down have ended, the control system will be reset to the
previously selected mode. If there is a power failure, the function will be maintained and
will continue from the point of disconnection.
A step pattern is defined using a start temperature and maximum temperature, step
duration and increment, and holding duration of the maximum value.
