Choose whether the heating circuit is to operate in dependence of
the DHW circuit.
OFF: Independent parallel operation, i.e. the

Temp.
100% parallel
operation
If the actual DHW charging temperature deviates more than
the set value (line 43), the gear motor M1 in the heating circuit
will close to such an extent that the DHW charging temperature
stabilizes at the lowest acceptable value.
This applies to heating system types 1, 2, 2a, 3, 4, 6 and 6a.

DHW and the heating circuits operate
independently of each other. It makes
no difference whether the desired DHW
charging temperature can be reached.
Dependent parallel operation, i.e. the
desired heating temperature depends on
the DHW demand.
Choose how much the DHW charging
temperature (circuit II) can drop before the
desired heating temperature (circuit I) has
to be decreased.
