COMMISSIONING AND MAINTENANCE
EEPROM CONTROL
The burner controller automatically checks for errors in the mi-
crocontroller EEPROM and enters lockout if an error is detect-
ed. An error is indicated by the LED flashing (see the “Fault diag-
nosis - lockouts” section on page 49).
3.4 Error List
When a technical anomaly occurs, the control interface display
shows a text message (small digit) and a number (large digit),
which indicate the type and level of the detected error.
There are 3 error levels:
1 Permanent: heating and/or DHW requests are suspended
and burner and circulator are switched off. For the error to
disappear, keep the key ENTER/RESET on the control inter-
face pressed for 3 seconds or reset the power supply by
using the main switch.
2 Temporary: heating and/or DHW requests are suspend-
ed and burner and circulator are switched off. The error
disappears automatically when the cause which generated
it is solved.
3 Alert: the thermal unit is not locked out, but its functions
may be limited according to the signalled alert code.
The log of the last ten errors occurred can be viewed through
the error log (menu 9000 - installer level) (from Par. 9001 to Par.
9010).
