SWITCHING OFF
Temporary switching off
In case of absence for short periods of time, set the mode selector
(1 - fig. 1a) 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
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
(1 - fig. 1a) to (OFF).
Then, close the gas tap present on the 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 (2 - fig.1a) to (OFF)
- turn on the filling tap until the pressure value is between 1 and
1.5 bar.
Carefully close the tap.
Replace the mode selector on the initial position.
If pressure drop is frequent, contact the Technical Assistance Service.

To restore operation (deactivate alarms):
Faults A 01-02-03
Position the function selector to
(OFF), wait 5-6 seconds then
set it to the required position
(summer mode) or
(winter
mode).
If the reset attempts do not reactivate the boiler, contact the Techni-
cal Assistance Centre.
Fault A 04
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 (OFF)
and adjust the filling tap until the pressure reaches a value be
-
tween 1 and 1.5 bar.
Then position the mode selector to the desired position
(sum
-
mer) or
(winter).
The boiler will perform one purge cycle lasting approximately 2
minutes.
If pressure drops are frequent, request the intervention of the Tech-
nical Assistance Service.
Fault A 06
The boiler operates normally but cannot reliably maintain a con-
stant domestic hot water temperature, which remains set at around
50°C.
