To restore the functioning after the appearance of a fault code of
the boiler press for a second the button BACK/RESET
If the reset attempts do not reactivate the boiler, request the intervent
of the Technical Assistance Centre.
The A99 fault code means that you have exceeded the maximum
number of reset possible by remote control BeSmart.
In this case, the operations of RESET must be carried out ONLY
from the panel of the boiler as indicated below:
- set the mode selector to
it to the Desired position
Fault A 04
Anomalia A 04
Check the pressure value indicated by the manometer, if less than
0.3 bar position the function selector to
to fill the boiler until the pressure reaches a value of between 1 and
1.5 bar.
Then press the BACK/RESET
If pressure drops are frequent, request the intervention of the
Technical Assistance Centre.
Fault A 06
The boiler functions normally but does not guarantee a constant
domestic hot water temperature, which remains set at around 50°C.
Contact the Technical Assistance Centre.
Fault A 07
Contact the Technical Assistance Centre.
Fault A08
Contact the Technical Assistance Centre.
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 (alarm code 09 with
flue gases probe counter >2.500).
Once the cleaning operation has been completed, reset to zero the
total hour meter with special kit supplied as an accessory following
procedure indicated below:
disconnect the electrical supply;
remove the shell and turn the instrument panel;
remove the electrical parts inspection cover, undoing the 2 fixing
screws;
as you electrically power the boiler press the CO button for at least
4 seconds to check that the counter resets. Remove and restore
power to the boiler; on the display the counter is shown after the
"-C-" indication.
Live electrical parts (230 Vac).
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 totalled hours multiply the value shown by
100 (ex: shown value of 18 = pre totalled 1.800 – shown value of 1=
totalled hours 100). The boiler continues to operate normally even
with the alarm active.
Fault A77
The fault is self-resetting, if the boiler does not restart contact the
Technical Assistance Centre.

Boiler configuration
On the electronic card there is a series of jumpers (JPX) which allow
the boiler to be configured; access is possible by removing the elec-
trical parts inspection cover after setting the main switch to off.
To access the card operate as follows:
- set the system's main switch to off
- undo the shell fixing screws, then move the shell base forward and
then upwards to unhook it from the chassis
- lift and then turn the instrument panel upside down
- remove the electrical parts inspection cover, undoing the 2 fixing
screws to access the jumpers (fig. 39)

(winter).
(OFF) and turn the tap

Setting the thermoregulation
Thermoregulation works only with the external probe connected,
therefore, once installed, connect the external probe to the specific
connection provided on the boiler terminal board.

T80 - maximum std system heating set point temperature (JP7 not on)
T45 - maximum floor system heating set point temperature (JP7 on)
The compensation curve for heating maintains a theoretical temper-
ature of 20°C indoors, when the external temperature is between
+20°C and -20°C. The choice of the curve depends on the minimum
external temperature envisaged (and therefore on the geographical
location), and on the delivery temperature envisaged (and therefore
on the type of system). It is carefully calculated by the installer on the
basis of the following formula:
