II
, the status of the appliance can be determined from the display.
The first 2 digits show the status of the boiler, the last 2 digits display the current flow temperature, except with
status 1, 2 or 5 when the number indicates the burner module about to start.
All other displays refer to error messages, see Frames 46 and 47 in the Installation & Servicing Instructions for
details.

of the boiler.
