    Power 5.X.4. POWER This option enables the boiler to operate at the selected power (D6 or D2) so that the combustion flue gases can be measured. The boiler operates at selected power until this option is deactivated or the temperature in the boiler rises 3 °C less than the maximum boiler temperature (in this case, the boiler reduces the power).
