Given the OK for selection, pass to the second
level where it is possible to set the value of the
parameter selected. e value is indicated by the
slow ashing of one of the LEDs between 1 and
8. e value is selected by rotating the heating
temperature selector switch (11).
Once the value of the parameter to be modied
has been selected, confirm the selection by
momentarily turning the main selector switch
onto Reset momentarily until the LED relative to
the parameter switches-o, then release.
Programming mode is exited if no operation is
carried out for 30 seconds or if the main selector
switch is positioned at OFF from the “parameter
setting” level.
For association of the LED to the relative value,
see the following tables:
Heating power. The boiler is produced and
calibrated in the heating phase at nominal power.
It also has electronic modulation that adapts the
boiler potentiality to the eective heating demand
of the house. en the boiler works normally in a
variable gas pressure eld between the minimum
heating power and the maximum heating power
depending on the plants heating.
N.B: the selection of the “Minimum heating power”
and “Maximum heating power” parameters, in the
presence of a heating demand , allows switch-on
of the boiler and power supply of the modulator
with current equal to the value of the respective
selected parameter.

Permanent reduction of the timer. e boiler
has an electronic timing device that prevents the
burner from igniting too often in the heating
phase. e boiler has a standard supply of a timer

boiler is set to switch-on immediately after a
request. In the case of particular plants (e.g. area
plants with motorised thermostatic valves etc.) it
could be necessary to delay switch-on.

Domestic water thermostat/Boiler hysteresis.
With the setting of hysteresis 1 the boiler switches
on with a boiling device temperature equal to a
set point at -3°C. With the setting of hysteresis
2 l the boiler switches on with a boiling device
temperature equal to a set point at -10°C.

Circulating pump function. two circulating
pump operational modes can be selected in
heating phase.
In “intermittent” mode it is activated from the
environmental thermostat or from the remote
control, in “continual” mode the circulation pump
functions constantly when the main selector switch
(12) is on heating mode.

3.8 AUTOMATIC SLOW IGNITION
FUNCTION WITH TIMED RAMP
DELIVERY.
In the switch-on phase the electronic card carries
out an increasing gas delivery ramp (with pressure
values that depend on the type of gas selected) of
preset duration. is avoids every boiler lighting
phase calibration or preparation operation in any
conditions of use.
3.9 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 temperature safety thermostat and the
limit thermostat remain active. To activate the
“Chimney-Sweep” function, press the Reset key
for 8 to 15 seconds in absence of domestic water
and heating requests. Its activation is indicated
by the simultaneous ashing of LEDS (2) and
(3). is function allows the technician to check
the combustion parameters. After the checks
deactivate the function, switching the boiler o
and then on again.
