6 . 7 Burner control units and ignition
transformers
ECOMAX burners with burner control unit BCU
ECOMAX burners are designed for On/Off control.
We recommend burner control unit BCU 460..L or
BCU 465..L. In order to be able to carry out ionization
control up to 1150°C, the burner control unit must be
equipped with firmware FW 16xx or higher.
ECOMAX · Edition 10.17
For burners ECOMAX..K with additional cooling air
connection, we recommend using burner control unit
BCU..C with additional circuit board for signal distribu-
tion.
For ignition, the ECOMAX burners require an ignition
transformer with 7.5 kV high voltage and an output cur-
rent of 20 mA. An appropriate ignition transformer is
already integrated in burner control units BCU 460..8
and BCU 465..8.
For further information on burner control units and ig-
nition transformers, see www.docuthek.com, Technical
Information BCU 460, 465.
