Setting heating programs
The heating system frost protection (see
frost protection function) applies to all
heating programs. You can set the
following heating programs with the
program selection keys:
H Heating and DHW
H DHW only
H Standby mode
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 20 ºC.
The circulation pump will be switched ON
simultaneously with the burner and
switched OFF after a delay.
The DHW cylinder is heated to
approx. 20 ºC.
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.
Summer mode
Heating program "w"
The burner starts only when the cylinder
needs reheating or when DHW is drawn
from a combi boiler.
Boiler water temperature sensor
The boiler water temperature sensor is
connected to the control unit and built
into the boiler.
Permissible ambient
temperature
H in operation: 20 ºC to +130 ºC
H during storage
and transport: 20 ºC to +170 ºC
