If the chimney sweep function is pressed for more than 3 seconds, the controller changes into
chimney sweep function mode. The "special mode" symbol appears in the display. Adjustment of
the burner output power and selection of burner is possible in the Information-Level.
The burner output power may be adjusted:
Engine burner minimum firing rate
ㆍ ㆍ ㆍ ㆍ
Engine burner maximum firing rate
ㆍ ㆍ ㆍ ㆍ
Supplementary burner minimum firing rate
ㆍ ㆍ ㆍ ㆍ
Supplementary burner maximum firing rate
ㆍ ㆍ ㆍ ㆍ
Engine- and Supplementary burner minimum firing rate
ㆍ ㆍ ㆍ ㆍ
Engine- and Supplementary burner maximum firing rate
ㆍ ㆍ ㆍ ㆍ
The burner will start like in commissioning mode. The head temperature will be controlled to
nominal head temperature and the boiler flow temperature will be limited to boiler temperature
set point maximum. If the burner output power is limited either by head temperature or boiler
flow temperature, this will be indicated with a * next to the burner state indication (e.g.1*)
The engine grid connection functionality may prevent starting of the engine burner. E.g. if the
head temperature is too high, it may be necessary to cool down the head before the engine
burner is enabled to start.
After 60 minutes, a time out will terminate the chimney sweeper function, it the function is not
already terminated by pressing the chimney sweeper button.
