Heating mode
The set boiler water temperature will
be maintained in the "central heating
and DHW heating"
G
program,
when a demand is raised by the room
temperature-dependent clock thermo-
stat. If no demand is received, the boi-
ler water temperature will be held at
the defaulted frost protection tem-
perature.
DHW heating
The DHW heating will be activated if
the cylinder temperature falls 2.5 K
below the set cylinder temperature.
The burner and the cylinder loading
pump are switched ON. In the deliv-
ered condition, the set boiler tempera-
ture lies 20 K higher than the set DHW
temperature (adjustable in coding
address 60). If the actual cylinder
temperature rises 2.5 K above the set
cylinder temperature, the burner will
be switched OFF and the cylinder
loading pump run-on time will be acti-
vated.
