Operating phases
Modulation mode
The boiler is in the "Modulation mode" operating phase, i.e. in normal heating mode. The boiler output is controlled in
a continuously variable manner.
Step-loading
If the "Step-loading" function is set, the system automatically changes to the "Step-loading" operating phase once the
step-loading conditions are met.
Blower OFF
If the boiler temperature exceeds 87 °C (90 °C), the blower switches off and only switches on again when the boiler tem-
perature drops below the set "restart temperature" (65–75 °C) or automatically after 2 hours. The system then switches
to the "Flame stabilisation" operating phase.
Burnout
The boiler enters burnout at the end of combustion. The blower continues to run until the combustion chamber has
cooled down. The blower then turns off and the system switches to the "Stand-by" operating phase.
