Heating program w
The burner starts only when the cylinder
needs reloading or when DHW is drawn
from a combi boiler.
Boiler temperature sensor
The boiler temperature sensor is
connected to the control unit and built
into the boiler.

Frost protection
The frost protection function is active in
all heating programs.
The burner is switched ON when the
boiler water temperature reaches 5 ºC and
will be switched OFF again, when the
boiler water temperature reaches 15 ºC.
The circulation pump will be switched ON
simultaneously with the burner and
switched OFF after a delay.
To protect the system from frost, the
circulation pump may be started at
certain intervals (up to 24 times per day)
for periods of approx. 10 minutes.
