The heating circuit pump is switched OFF during cylinder heating with DHWpriority
(0). The boiler energy will then be used exclusively for DHW heating. 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, in summer operation and at most,
for the period selected under parameter HG19 (cylinder primary pump run-on time).
In winter mode, the cylinder loading pump runs on for a xed time of 2 minutes after
successful cylinder heating.
The heating circuit pump continues to operate in parallelDHWmode(1). Cylinder
heating ends when the cylinder reaches the set water temperature. The cylinder primary
pump runs on, in summer operation and at most, for the period selected under parameter
HG19 (cylinder primary pump run-on time).
InparallelDHWmode(1),theheatingcircuitcantemporarilybeoperated
atahighertemperature.
Parallel operation in conjunction with a stratification cylinder is not
recommended.

The boiler circuit pump operates constantly if the outside temperature stays below the
selected value. The burner starts and heats the boiler to at least 20 °C if the boiler water
temperature falls below +5 °C.
Thefactorysettingmayonlybechangedifitisguaranteedthatheating
systemanditscomponentswillnotfreezeatlowexternaltemperatures.
Incorrectoperationcanleadtosystemfaults.
