Automatic Adjustment Control System Function (S.A.R.A.) fig. 7a
By setting the heating water temperature selector to the area
marked by AUTO - temperature value from 55 to 65°C - the
S.A.R.A. self-adjusting system is activated, the green LED flashes
(frequency 0.1 sec. on; then 0.1 sec. off; for 0.5 seconds): the boiler
varies the delivery temperature according to the closing signal of
the room thermostat. When the temperature set with the heating
water temperature selector is reached, a 20 minutes count begins.
If during this period the room thermostat still requests heat, the
value of the set temperature automatically increases by 5 °C.
When the new value is reached, other 20 minutes count begins.
If during this period the room thermostat still requests heat, the
value of the set temperature automatically increases by 5 °C.
This new temperature value is the result of the temperature set
manually 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 room thermostat is met.
3A SWITCHING OFF
Temporary switching off
In case of absence for short periods of time, set the mode selector
(6b) 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
- 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
(6b) 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 (3 - fig.1a) to
- turn on the filling tap (L - fig. 13) 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.
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, position the function selector to
and adjust the filling tap (L - fig. 13) until the pressure reaches a
value between 1 and 1.5 bar.
Then position the mode selector to the desired position
(summer) or
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 domestic hot water temperature, which remains set at
around 50°C. Contact the Technical Assistance Centre.
