Under diagnosispoint "d.0" you can set a value which corresponds tothe required output in the heating system in kW.7.2.2 Setting the pump overrun timeThe pump overrun time for the heating operation is set inthe factory to a value of 5 minutes. It can be set underdiagnosis point "1" within the range two minutes to60 minutes. Under diagnosis point "d.18" you can set theoverrun behaviour of the pump to a different mode.Overrun: After completion of the heat demand the heatingpump continues to run for the time set under "d.1".Continuous: The internal heating pump is switchedon when the rotary knob for setting the heating feedtemperature is not in the left-hand stop position and theheat demand is released by an external controller.Winter: The internal heating pump is switched on whenthe rotary knob for setting the heating feed temperatureis not in the left-hand stop position.7.2.3 Setting the maximum flow temperatureThe maximum feed temperature for the heating is set inthe factory to 75 °C. Under diagnosis point "d.71" it canbe set to between 40 und 85 °C.7.2.4 Setting the return temperature controlWhen connecting underfloor heating or wall heating tothe appliance which does not have its own temperatureregulation, the temperature regulation mode can bechanged from feed temperature regulation (factory set-ting) to return temperature regulation under diagnosispoint "d.17".7 Adapting the appliance to the heating system
