5A LIGHT SIGNALS AND FAULTS
The control panel has three LEDs that indicate the boiler operating status:
Green LED
Flashing
Flashing (0.5 seconds on, then 3.5 seconds off ) = boiler in standby, there is no
fl ame.
Flashing (0.5 seconds on, then 0.5 seconds off ) = temporary shutdown of the
appliance due to the following automatic-reset faults:
- water pressure switch (standby time 10 minutes approximately)
- transitory waiting for ignition.
In this phase, the boiler waits for restoration of working conditions. If after the
standby time, the boiler does not restore regular operation, the shutdown will
be permanent and the signal light will be red.
Fixed green
there is fl ame, the boiler works regularly.
Red LED
If the red LED lights up, this indicates the presence of a fault; the monitor shows
a code interpreted as follows:
To restore operation (deactivate alarms):
Faults A 01-02-03
Position the function selector (3 - fi g.1) to
to ON position.
If the reset attempts do not reactivate the boiler, contact the Technical Assistan-
ce Centre.
Fault A 04
In addition to the fault code, the digital display shows the symbol
Check the pressure value indicated by the water gauge:
if it is less than 0.3 bar, position the function selector (3 - fi g.1) to
adjust the fi lling tap of the system until the pressure reaches a value between 1
and 1.5 bar.
Then position the function selector (3 - fi g.1) to the ON position.
The boiler will perform one purge cycle lasting approximately 2 minutes.
If pressure drops are frequent, request the intervention of the Technical Assi-
stance Service.
Fault A 06
Contact the Technical Assistance Centre.
Fault A 07
Contact the Technical Assistance Centre.
Fault A 08
Contact the Technical Assistance Centre.
Fault A 09 with fi xed red LED lit
Position the function selector (3 - fi g.1) to
to the ON position.
If the reset attempts do not reactivate the boiler, request the intervention of the
Technical Assistance Service.
Fault A 09 with fl ashing red and green LEDs
The boiler is equipped with an auto-diagnostic system which, based on the total
number of hours in certain operating conditions, can signal the need to clean
the primary exchanger (alarm code 09 with fl ashing red and green LEDs and fl ue
gas meter >2,500). Once the cleaning operation has been completed, using the
special kit supplied as an accessory, the total hour meter will need to be reset to
zero as follows:
- switch off the power supply
- remove the housing loosening the fi xing screw then turn the instrument pa-
nel
- loosen the fi xing screws on the cover (F) to access the terminal board (fi g. 13)
- while the boiler is powered up, press and hold the CO button (fi g. 23) for at
least 4 seconds, to check the meter has been reset, power down then power
up the boiler; the meter reading is shown on the monitor after the "-C-" sign.
Live electrical parts (230 V AC).
Note: the meter resetting procedure should be carried out after each in-depth
cleaning of the primary exchanger or if this latter is replaced. To check the status
of the total hour meter, multiply the reading by 100 (e.g. reading of 18 = 1800
total hours; reading of 1 = 100 total hours).
The boiler continues to operate normally even when the alarm is activated.
Fault A77
This is an automatic-reset fault, if the boiler does not restart, contact the Techni-
cal Assistance Centre.
