Intermediate heating
This function can only be activated in systems Anl 2.x, 4.1 and 4.5.
With the setting CO4 > F07 - 1, heating operation of the UP1 heating circuit is reactivated
for a period of ten minutes after 20 minutes of priority operation (heating deactivated during
DHW heating). By setting CO4 > F07 - 0, storage tank charging is given unlimited priority
over the heating operation in the UP1 heating circuit.

7.6 Parallel pump operation
This function can only be activated in systems Anl 2.1 to 2.1, 4.1 and 4.5.
With the setting CO4 > F06 - 1, the circulation pump UP1 remains activated during DHW
heating.
This does not include operating situations during which the current flow temperature demand
of the pump circuit is lower than the adjusted 'Flow temperature limit for parallel operation'.
In this case, the controller applies priority operation, if necessary with intermediate heating.
Once a parallel pump operation cycle has been activated and the time period set in 'Stop
parallel pump operation in the event of a system deviation' has elapsed, system deviations
greater than 5 °C cause the controller to suspend parallel operation for 10 minutes and to
apply priority operation.
Setting 'Stop parallel pump operation in the event of a system deviation' to 0 min leads to a
parallel operation once initiated remaining regardless of a deviation.
