DHW heating
The burner and the cylinder primary
pump are started if the cylinder tem-
perature lies 2.5 K below the set cylin-
der temperature.
In the delivered condition, the set boil-
er water temperature is 20 K higher
than the set DHW temperature (adjus-
table via coding address "60"). The
burner will be switched OFF and the
circulation pump run-on time will
begin, if the actual cylinder tempera-
ture exceeds the set cylinder tem-
perature by 2.5 K.
