7.2.9Conditional 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 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.

7.2.10Circulation pump control mode

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

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

Access level HS (heating specialist)

Function 1

Function as before

2While hot-water loading is active, the circulation pump is switched off
