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

Adjustment of the domestic hot water temperature
CASE A heating only with storage tank - adjustment does not apply.
CASE B heating only + external storage tank with thermostat - adjustment
does not apply.
CASE C heating only + external storage tank with probe - to adjust the
temperature of the domestic hot water in the storage tank, turn the knob
with the symbol (fig. 32) clockwise to increase water temperature and
anti-clockwise to lower it.
The boiler is standby status until, after a heat request, the burner switches
on. The boiler continues to operate until the temperatures set on the boiler
are reached, or the heat request is met; after which it goes back on standby.
The digital monitor indicates the fault code detected.
Automatic Temperature Control System function (S.A.R.A.) fig. 34
Setting the heating water temperature selector to the area marked "AUTO"
(temperature range 55 to 65°C), activates the automatic temperature con-
trol system: according to the temperature set on the room thermostat and
the time taken to reach it, the boiler varies automatically the heating water
temperature reducing the operating time, allowing greater ease of operation
and energy saving.
Reset function
To restore operation, set the function selector to
onds then set the function selector to the required position.
At this point the boiler will automatically start.
N.B. If the attempt to reset the appliance does not activate operation, con-
tact the Technical Assistance Service.
4.2 Switching off
Temporary switch-off
In case of absence for short periods of time, set the mode selector (fig. 31)
to (OFF).
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.
DHW Antifreeze (only when connected to an external storage tank with
probe): the function is activated if the temperature measured by the storage
tank probe drops below 5° C. A heat request is generated in this phase with
the ignition of the burner at minimum power, which is maintained until the
water temperature reaches 55° C. During the anti-frost cycle, the symbol
(fig. 35) appears on the digital monitor.
Switching off for long periods
In case of absence for long periods of time, set the mode selector (fig. 31) 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.

If the reset attempts do not reactivate the boiler, contact the Technical As-
sistance 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
the filling tap until the pressure reaches a value between 1 and 1.5 bar.
Then position the mode selector to the desired position
(winter). The boiler will perform one purge cycle lasting approximate-
ly 2 minutes. If pressure drops are frequent, request the intervention of the
Technical Assistance Service.

Fault A09
Position the function selector to
required position (summer mode) or (winter mode).
If 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 (flue gas meter >2,500).
Once the cleaning operation has been completed, using the special kit sup-
plied as an accessory, 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.
