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

4 - SWITCHING ON AND OPERATION
4.1 Switching on the appliance
b
The first time you turn the boiler on and in case of maintenance
work, before using the appliance you must fill the siphon with water
and make sure that the condensation is evacuated correctly. Fill the
condensation collection siphon pouring 1 litre of water into the boiler
combustion-analysis outlet with the boiler off, and check that:
- the safety cut-off device is floating
- water is flowing correctly from the discharge pipe out of the boiler
- the condensate outlet connection line is watertight.
If the condensate outlet circuit (siphon and pipes) is working correctly, the
condensation level will not exceed the maximum.
Filling the siphon before using the appliance, and the use of a safety cut-off
device inside the siphon, prevent exhaust gases from being released into
the environment.
Repeat during standard and non-standard maintenance work.
Every time the appliance is powered up, a series of data is shown on the
display including the flue gas sensor meter reading (-C- XX) (see paragraph
4.3 - fault A09); the automatic purge cycle then starts, lasting around 2
minutes. During this phase the symbol
25). To interrupt the automatic purge cycle proceed as follows:
access the electronic board by removing the housing, turning the instrument
panel towards you and opening the board casing (fig. 16).
Then:
- using a small screwdriver included, press the CO button (fig. 26).

Live electrical parts.
To start up the boiler it is necessary to carry out the following operations:
- power the boiler
- open the gas tap to allow the flow of fuel
- set the room thermostat to the required temperature (~20°C)
- turn the mode selector to the desired position:
Winter mode: by turning the mode selector (fig. 27) within the area marked
"+" and "-", the boiler provides domestic hot water and heating. If there is
a heat request, the boiler switches on. The digital monitor indicates the
heating water temperature, the icon to indicate heating and the flame icon
(fig. 29).
If there is a domestic hot water request, the boiler switches on.
The digital display shows the hot water system temperature, the icon to
indicate the hot water supply and the flame icon (fig. 30).
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with symbol
(fig. 27) within the area marked "+" and "-".
Depending on the type of system, it is possible to pre-select the suitable
temperature range:
- standard systems 40-80°C
- floor systems 20-45°C.
For further details, consult the "Boiler configuration" section.
Adjusting heating water temperature with an external probe connected
When an external probe is connected, the value of the delivery temperature
is automatically chosen by the system which rapidly adjusts ambient
temperature to the changes in external temperature.
To increase or decrease the temperature with respect to the value
automatically calculated by the electronic board, turn the heating water
selector clockwise to increase and anticlockwise to decrease.
Adjustment settings range from comfort levels - 5 to + 5 which are indicated
on the digital display when the knob is turned.
Summer mode: turning the selector to the summer mode symbol
28) activates the traditional domestic hot water only function.
If there is a domestic hot water request, the boiler switches on. The digital
display shows the hot water system temperature, the icon to indicate the
hot water supply and the flame icon (fig. 30).
MAX
is shown on the monitor (fig.
Pre-heating (faster hot water): turning the domestic hot water temperature
adjustment knob to the
function, the monitor indicates the fixed
water temperature adjustment knob back to the required position.
This function keeps the water in the domestic hot water exchanger hot, to
reduce standby times when a request is made.
The monitor indicates the delivery temperature of the heating water or
the domestic hot water, according to the current request. During burner
ignition following a pre-heating request, the monitor indicates the flashing
symbol and the flame icon.
To deactivate the pre-heating function, rotate the domestic hot water
temperature adjustment knob back to the
hot water temperature adjustment knob back to the required position.
This function cannot be activated when the boiler is OFF: function selector
(fig.32) to (OFF).
Adjustment of the domestic hot water temperature
To adjust the domestic hot water temperature (bathrooms, shower, kitchen,
etc.), turn the knob with the
the temperature and anticlockwise to reduce 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.
If the symbol (fig. 34) on the control panel lights up, this means the
boiler is in temporary shutdown status (see the chapter on "Light signals
and faults"). The digital monitor indicates the fault code detected (fig. 34).
Automatic Temperature Control System function (S.A.R.A.) fig. 35
Setting the heating water temperature selector to the area marked "AUTO"
(temperature range 55 to 65°C), activates the automatic temperature
control 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
seconds then set the function selector to the required position.
N.B. If the attempt to reset the appliance does not activate operation,
contact 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.
32) 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
minimum 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.
