Boiler Status - Beretta Ciao Green 25 C.S.I. Manual De Instalacion Y Uso

In this way (leaving the electricity and fuel supplies enabled), the boiler is
protected by the following systems:
Anti-frost device: when the temperature of the water in the boiler falls
below 5°C, the circulator and, if necessary, the burner are activated at mini-
mum output levels to bring the water temperature back to the values for
safety (35°C). During the anti-frost cycle, the symbol
on the digital monitor.
Circulator anti-blocking function: an operation cycle is activated every
24 hours.
Switching off for long periods
In case of absence for long periods of time, set the mode selector (fig. 32) to
(OFF). Turn the main system switch OFF. Close the fuel and water taps
of the heating and domestic hot water system. In this case, anti-frost device
is deactivated: drain the systems, in case of risk of frost.

To restore operation (deactivate alarms):
Faults A 01-02-03
Position the function selector to
the required position (summer mode) or
If the reset attempts do not reactivate the boiler, contact the Technical As-
sistance Service.
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
the pressure reaches a value between 1 and 1.5 bar. Then position the mode
selector to the desired position
perform one purge cycle lasting approximately 2 minutes. 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 do-
mestic hot water temperature, which remains set at around 50°C. Contact
the Technical Assistance Service.
Fault A07 - A08
Contact the Technical Assistance Service.
Fault A09
Position the function selector to
the required position (summer mode) or (winter mode). If the reset attempts
do not reactivate the boiler, request the intervention of the Technical As-
sistance 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 (flue gas meter >2,500). Once the cleaning
operation has been completed, using the special kit supplied as an acces-
sory, the total hour meter will need to be reset to zero as follows:
- switch off the power supply
- remove the housing
- loosen the fixing screw then turn the instrument panel
- loosen the fixing screws on the cover (F) to access the terminal board (fig. 16)
- while the boiler is powered up, using a small screwdriver included, press
the CO button (fig. 26) 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
Technical Assistance Service.
4.4 Boiler configuration
There is a series of jumpers (JPX) available on the electronic board which
enable the boiler to be configured.
To access the board, proceed as follows:
- turn off the main switch on the system
- loosen the fixing screws on the housing, move the base of the housing
forwards and then upwards to unhook it from the chassis
- undo the fixing screws (E) from the instrument panel (fig. 14)
- loosen the screws (F - fig. 16) to remove the cover of the terminal board
(230V).
