Abstract (en)

[origin: EP1304527A1] The method involves comparing a heat exchanger (11) actual value (14) with a demand value (15), deriving a burner control signal (10) in a first controller (13), comparing the control signal with a burner actual value (18) and deriving a modified burner control signal (19) in a second controller (17). Only the maximum burner load is used for regulation initialization or calibration and the ionization signal is determined at maximum burner load.
