6 .3 Recommended burner control units
ECOMAX burners, indirectly heated, with burner control unit
BCU 465
Depending on the type of heating, we recommend operating
ECOMAX burners with the burner control units BCU 460..L..8
or BCU 465..L..8. When using burners ECOMAX..K with the
additional cooling air connection, we recommend operation
with a burner control unit BCU..C with additional circuit board
for signal distribution.
For ignition, the ECOMAX burners require an ignition trans-
former with 7.5 kV high voltage and an output current of 20 mA
at a duty cycle of 33%. An appropriate ignition transformer is
already integrated in burner control units BCU 460..L..8 and
BCU 465..L..8.
On request, we can also provide parameter lists for the pro-
grammable air supply and air post ventilation on the BCU 465.
