16.3.7 Circulation pump during storage tank charging
WiththesettingCO4->F11-1,thecirculationpump(DHW)continuesoperationaccording
to the programmed time schedule even during storage tank charging. With the setting
CO4->F11-0,thecirculationpumpisswitchedoffassoonasthestoragetankcharging
pump is activated. The circulation pump starts to operate again according to the time sched-
ule when the storage tank charging pump has been switched off again.

16.3.8 Priority circuit
In many district heating systems with primary DHW heating, the allotted amount of water
cannot meet DHW heating and heating operation demands when they are required at the
same time. As a result, the capacity required for DHW heating needs to be taken from the
heatingsystemwhengreatheatingloadsoccur;andthis,untilDHWdemandhasbeencon-
cluded. Nevertheless, heating operation is not to be interrupted simply. Only the amount of
energy required for DHW heating is to be deducted. This can be achieved by using the pri-
ority functions: reverse control and set-back operation.
The priority functions (reverse control and priority operation) can be activated for each heat-
ing circuit separately in system Anl 4.5.
