The ecoCRAFT units are fitted with a digital information
and analysis system. This system provides information
on the operating status of your appliance and helps you
deal with problems.

the display shows a single figure operating code. This
indicates the current operating condition of the boiler
and the current temperature at the feed manifold, e.g.:
"3 45" = Burner in heating operating mode "3",
forward flow temperature
