Flue gas temperature limit
1:...
Boiler regulates to a maximum of
the factory-set flue gas tempera-
ture.
Note
Factory setting depends on the rat-
ed boiler heating output:
20 kW: 150 °C
30 kW: 160 °C
40 kW: 170 °C
50 kW: 190 °C
Flue gas temperature minimum
2:...
Boiler regulates to a min. flue gas
temperature set at the factory.
Note
Factory setting depends on the rat-
ed boiler heating output:
20 kW: 100 °C
30 kW: 110 °C
40 kW: 120 °C
50 kW: 130 °C
Dissipate heat
44:90
Temperature in °C. If the boiler wa-
ter temperature exceeds 90 °C,
the heat is transferred to the heat-
ing circuit set in code "F3" (Heat-
ing group). For this, the boiler reg-
ulates to the max. flow tempera-
ture (code "C6", Heating group) of
the heating circuit.
Set system temperature

The min. set system temperature
can be adjusted in the menu.

If no signal from the Hall sensor is
detected, the flue gas fan is regu-
lated to 60 % of the max. speed.
Buffer maximum temperature
FC:80
