Operating principle
This is a fully modulating boiler.
The control unit of the boiler adapts
the modulation ratio automatically to
the heat demand requested by the
system. This is done by controlling
the speed of the fan.
As a result, the Whirlwind mixing
system will adapt the gas ratio to the
chosen fan speed, in order to maintain
