Diagnostics
LCD display Off
If, even after touching the buttons, the display does not come on, check that the card is electrically
powered. Using a digital multimeter, check for presence of power.
In case of no voltage, check the wiring.
If the voltage is sufficient ( Range 195 – 253 Vac), check the fuse (3.15AL@230VAC). The fuse
is on the card. To access it, see fig. 29.
LCD display On
In case of operation problems or faults, the display shows the fault identification code.
There are faults that cause permanent shutdowns (indicated with the letter "A"): to restore opera-
tion, just hold down the button
ton , or use the RESET of the remote timer control (optional) if installed. If the boiler does not
restart, the fault must be eliminated.
Other faults cause temporary shutdowns (indicated with the letter "F") which are automatically re-
set as soon as the value returns within the boiler's normal working range.

No 230V power supply
Tachometric signal interrupted
Fan damaged
Ionization electrode fault
Flame unstable
air/fume ducts obstructed
Trap blocked
Wrong calibration
Insufficient gas supply pressure
Flow or return sensors incorrectly
positioned or damaged

Cure
Check the regular gas flow to the boiler and that
the air has been eliminated from the pipes
Check the wiring of the electrode and that it is
correctly positioned and free of any deposits;
replace the electrode if necessary.
Check the gas supply pressure
Check the trap and clean it if necessary
Remove the obstruction from the flue, fume
extraction ducts, air inlet and terminals.
Do the Calibration procedure [AUTO SETUP].
Check the gas valve and replace it if necessary
Check the ionization electrode wiring
Check the condition of the electrode
Electrode to ground
Cable to ground
Check the trap and clean it if necessary
Check the card
Check the 5-pin connector wiring
Check the fan and replace it if necessary
Check the position of the ionization electrode,
free it from any encrustations and do the Calibra-
tion procedure [AUTO SETUP]. Replace the elec-
trode if necessary.
Check the burner
Remove the obstruction from the flue, fume
extraction ducts, air inlet and terminals
Check the trap and clean it if necessary
Do the Calibration procedure [AUTO SETUP].
Check the gas supply pressure
Check the correct positioning and operation of
the sensors and replace them if necessary.
