Fault A09
Position the function selector to
to the required position (summer mode) or
the reset attempts do not reactivate the boiler, request the intervention
of the Technical Assistance Service.
Fault A09
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 and flue 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 shell
- turning the instrument panel towards you
- unscrew the two screws of the small cover on the electronic board to
have access to the terminals

Live electrical parts.
Note: the meter resetting procedure should be carried out after each
indepth 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 = 1,800 total hours; reading of 1 = 100 total hours).
The boiler continues to operate normally even when the alarm is
activated.
