The efficiency rate must be individually calculated for each fuel. The calculation is performed separately in:

[30] Efficiency related to exhaust gas losses

The calculated efficiencies of the fuels must be written to the following analog channels:

Fuel [1 - 3]: Efficiency: Firing

Fuel [1 - 3]: Efficiency: Boiler

The system automatically checks which fuel is currently used in single operation. The corresponding values are written to the following outputs:

Efficiency: Firing

Efficiency: Boiler

These two analog channels thus always reflect the current efficiencies. If no fuel is used or mixed firing is active, the efficiencies are set to 0%.
