4 MAIN FEATURES FOR THE TECHNICAL ASSISTANCE
SERVICE
4.1 SELF-DIAGNOSIS
To make it easier for the technical assistance service to identify the problem, the boiler is fitted with a state-
of-the-art self-diagnosis system, which shows the error code offering further information on the display.
The new error codification was thereby introduced; errors are no longer divided into type A and type E faults.
The main features of the new codification are as follows:
(D1) error codes are divided into six groups;
(D2+D3) indicating the group to which it belongs.
EXAMPLE :
Code 501: No flame
The boiler stores the last 10 errors in its memory (Operating Shutdown, Safety
Shutdown and Warning Signals), helping the technical assistance service during
maintenance work.
Standardisation on a component level has led to the unification of the main
components and a reduction in the number of spare part codes, thereby greatly
facilitating the various necessary maintenance activities.
