Switching Off - Beretta QUADRA II 24 C.S.I. Installation And User Manual

ENGLISH
This new temperature value is the result of the temperature set manu-
ally with the heating water temperature selector and the increase of
+10 °C of the S.A.R.A function.
After the second cycle the temperature value should be kept at the
set value +10°C until the request of the ambient thermostat is met.
3A SWITCHING OFF
Temporary switching off
In case of absence for short periods of time, set the mode selector
(fig. 6b) to (OFF), the green LED flashes ON for 0.5 seconds,
OFF for 3.5 seconds.
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 appears on the digital monitor.
- Circulator anti-blocking function: an operation cycle is activated
every 24 hours.
Long period switching off
In case of absence for long periods of time, set the mode selector
(fig. 6b) to (OFF), the green LED flashes ON for 0.5 seconds,
OFF for 3.5 seconds.
Turn the main system switch OFF. Close the gas and water taps of
the heating and domestic hot water system.In this case, anti-frost
device is deactivated: empty the systems, in case of risk of frost.
4A CONTROLS
At the beginning of the heating season, and occasionally during
use, make sure the hydrometer-thermohydrometer indicates cold
system pressure values between 0.6 and 1.5 bar: this avoids system
noise levels due to the presence of air. In case of insufficient water
circulation, the boiler will switch off. Under no circumstances, water
pressure must be below 0.5 bar (red field).
If this condition is checked, it is necessary to restore water pressure
in the boiler proceeding as follows:
- set the mode selector (fig. 6b) to
- turn on the filling tap until the pressure value is between 1 and 1.5
bar.

If pressure drop is frequent, contact the Technical Assistance Service.
5A LIGHT SIGNALS AND FAULTS
The operating status of the boiler is shown on the digital display,
below is a list of the types of displays.
To restore operation (deactivate alarms):
Faults A 01-02-03
Position the function selector to
set it to the required position
mode). 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, rotate the function selector to
adjust the filling tap until the pressure reaches a value between 1
and 1.5 bar.
Then rotate the mode selector to the desired position
or (winter).
If pressure drops are frequent, request the intervention of the Tech-
nical Assistance Service.
Fault A06
The boiler operates normally but cannot reliably maintain a con-
stant domestic hot water temperature, which remains set at around
50°C. Contact the Technical Assistance Centre.
Fault A07
