6.3Priority operation

In many district heating systems with primary DHW heating, the allotted amount of water is only intended to supply the heating system. 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 heating has been concluded.

Nevertheless, heating operation is not to be simply interrupted. Only the amount of energy re- quired for DHW heating is to be deducted. This can be achieved by using the priority functions Reverse control and Set-back operation.

6.3.1 Reverse control

In all systems with DHW heating and at least one heating circuit with a control valve, the DHW heating can be given priority by applying a reverse control. With the setting Co4 -> Fb06 = ON, the charging temperature can be monitored. If the temperature also falls below the charg- ing temperature after the time period set in function block Fb07 has elapsed, the heating circuit is closed and the set point remains the same.

Which circuit is closed depends on how the system (Anl) is configured:
