To restore operation (reset alarms):
Faults A 01-02-03
Position the function selector to
it to the required position
If the reset attempts do not reactivate the boiler, contact the Technical
Assistance Centre.
Fault A04
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 to
tap (C fig. 18 for C.S.I. - external for R.S.I.) until the pressure reaches
a value between 1 and 1.5 bar. Then position the mode selector to the
desired position (summer) or
If pressure drops are frequent, request the intervention of the Technical
Assistance Service.
Fault A06
The boiler operates normally but cannot reliably maintain a constant
domestic hot water temperature, which remains set at around 50°C.
Contact the Technical Assistance Centre.
Fault A07 - A08
Contact the Technical Assistance Centre.
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
- while the boiler is powered up, using a small screwdriver included,
press the CO button (fig. 42) 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.

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.
Fault A77 (only for
25 C.S.I. - 30 C.S.I./R.S.I. models)
The fault is self-resetting, if the boiler does not restart contact the

4.5 Boiler configuration
The electronic board contains a series of jumpers (JP4) that can be
used to configure the boiler.
To access the board, proceed as follows:
- switch off the power supply
- remove the shell (fig. 6)
- turning the instrument panel towards you (fig. 7)
- unscrew the two screws of the small cover on the electronic board to
have access to the terminals (B, fig. 8).
JUMPER JP7 (fig. 36):
preselection of the most suitable heating temperature adjustment field
according to the installation type.
Jumper not inserted - standard installation
Standard installation 40-80°C.
Jumper inserted - floor installation
Floor installation 20-45°C.
In the manufacturing phase, the boiler is configured for standard
installations.
JP1 Calibration (Range Rated)
JP2 Reset heating timer
JP3 Calibration (see paragraph on "Adjustments")
JP4 Absolute domestic hot water thermostat selector (C.S.I. model)
JP4 Do not use (R.S.I. model)
JP5 Do not use (C.S.I. model)
JP5 Heating only function with a predisposition for external storage
tank with thermostat (JP8 inserted) or probe (JP8 not inserted)
(R.S.I. model)
JP6 Enable night-time compensation function and continuous pump
(only with external sensor connected)
JP7 Enable management of low temperature/standard installations
(see above)
JP8 Do not use (C.S.I. model)
JP8 Management of an external storage tank with thermostat enabled
(jumper inserted)/ management of an external storage tank with
probe (jumpers not inserted) (R.S.I. model).
