Automatic slow ignition function with timed ramp delivery.
In the lighting phase the electronic card executes an increasing gas delivery
ramp (with pressure values depending on the type of gas selected) of fixed
duration. This avoids every operation for calibrating or setting the boiler
lighting phase in any operating conditions.
"Chimney Sweep" function.
When activated, this function forces the boiler at max. output for 15
minutes.
In this mode all the adjustments are cut out and only the safety thermostat
and the limit thermostat remain active. To activate the "Chimney Sweep"
function turn the main switch to Reset for 8 to 15 seconds in the absence
of domestic hot water and heating demands; its activation is signalled by
LEDs (3) and (4) flashing at the same time. This function allows the techni-
cian to check the combustion parameters. After the checks, deactivate the
function, switching the boiler off and then on again.
Pump antiblock function.
During the "Domestic" (
tion that starts the pump at least once every 24 hours for the duration
of 2.5 minutes in order to reduce the risk of it becoming blocked due to
prolonged inactivity.

with a function that starts the pump at least once every 3 hours for the
duration of 2.5 minutes.
three-way antiblock function.
During the "Domestic" and "Domestic-Heating" phase the boiler is
equipped with a function that activates the motor-driven three-way unit after
24 hours from the last time is was operated, doing a complete cycle in order
to reduce the risk of it becoming blocked due to prolonged inactivity.
Radiator antifreeze function.
If the system return water is at a temperature of below 4°C, the boiler
operates until reaching 42°C.
Electronic board periodical self-check.
During operation in heating mode or with boiler in standby, the function
activates every 18 hours after the last boiler check/feed. In case of operation
in domestic circuit mode the self-check starts within 10 minutes after the
end of the drawing in progress, for a length of approx. 10 seconds.
NB: During self-check, the boiler remains off, including signalling.
