7.2.9 Conditional parallel operation for mixed heating circuits
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.
7.2.10 Circulation pump control mode
During service water loading, it should be possible to switch off
the circulation pump.
New parameter: "Hot Water Circuit" menu, parameter 16 =
circulation pump.
