This function is only realised for district heating controllers. 

Additional setting in the "Hot Water" menu, parameter 07 ("Hot 
Water Circuit" control mode) = 8 (priority with enabling of mixed 
heating circuit control operation) 

 

Function as for hot-water priority operation (setting 2), with the 
difference that mixed heating circuits (mixed heating circuit 
control, constant control, fixed-value control) can still adjust to 
their setpoint. During an active hot-water loading, the heating 
circuits do post a setpoint value to energy management. Mixed 
heating circuits must operate at the temperature required by the 
hot-water demand. Direct heating circuits remain switched off. 

Hot-water loading with priority operation in the system has priority. 
The mixed heating circuits must shut in this case. 

 

During service water loading, it should be possible to switch off 
the circulation pump. 

 

New parameter: "Hot Water Circuit" menu, parameter 16 = 
circulation pump.
