5.8 DIAGNOSIS
5.8.1 Signalisation of error codes during the emergency procedures implementation
During the implementation of emergency procedures, a constant error code is displayed consisting of letter “E” and two
digits. Symbols and “RESET” are blanked. If the emergency procedure is completed successfully, the boiler will automatically
return to normal operation and the error code disappears. Unsuccessful completion of the emergency procedure results in
an emergency lock out.
5.8.2 Signalisation of error codes in emergency situations without locking
In emergency situations without lock out, the flashing symbols and the error code are displayed. Symbol “RESET” is blanked.
In particular cases, the error code can be displayed alternately with the temperature or pressure value in the C.H. circuit.
After removing the cause of failure, the boiler will automatically return to normal operation and the error code disappears.
5.8.3 Signalisation of emergency switch off with locking
An emergency lock is indicated by displaying the error code, flashing symbols, and “RESET” (see the figure below). A return
to normal operation is possible after removing the cause of failure and after pressing the reset button.
If after pressing the reset button the boiler remains locked, we advise you to contact an AUTHORISED SERVICE COMPANY.
The figure above shows an example of a display with error code E 01 with symbols reset and
