The boiler circuit pump operates constantly if the outside
temperaturestaysbelowtheselectedvalue.Theburnerstartsand
heatstheboilertoamin.of38°C,iftheboilerwatertemperature
fallsbelow+5°C.

The boiler circuit pump is switched OFF during DHW cylinder
heating with DHW priority (0). The boiler energy will then be
used exclusively for heating the DHW cylinder. The cylinder
primary pump will only start, if the boiler water temperature is
5 °C higher than the actual cylinder temperature. The burner
shutsdownandtheheatingcircuitpumpisstarted,assoonas
thecylinderhasreacheditssettemperature.Thecylinderprimary
pumprunsonforthemaximumperiodselectedunderparameter
HG19(cylinderprimarypumprun-ontime).
Theheatingcircuitpumpcontinuestooperateinparallel DHW

temperatureis5°Cwarmerthanthecylindertemperature.The
cylinder is fully heated up when the cylinder has reached the
