parameter selected. The value is indicated by the
slow flashing of one of the LEDs between 1 and
8. The value is selected by rotating the heating
temperature selector switch (11).
Once the value of the parameter to be modified
has been selected, confirm the selection by
momentarily turning the main selector switch
onto Reset momentarily until the LED relative to
the parameter switches off, 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 effective heating
demand of the house. Then the boiler works
normally in a variable gas pressure field 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. The boiler
has an electronic timing device that prevents the
burner from igniting too often in the heating
phase. The boiler has a standard supply of a timer
adjusted at 180 seconds.

Heating ramp timing. The boiler distributes he
maximum power set in the previous parameter.
The boiler performs an ignition ramp of about
650 seconds to arrive from minimum power to
nominal heating power.

Heating switch-on delay request from Room
thermostat and Remote Friend Control
V2
.
The
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 hysterisis.
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 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 selec-
tor switch (12) is on heating mode.

3.8 AUTOMATIC SLOW IGNITION
FUNCTION WITH TIMED RAMP
DELIVERY.
In the switch-on phase the electronic card car-
ries out an increasing gas delivery ramp (with
pressure values that depend on the type of gas
selected) of preset duration. This 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.
IIn 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 flashing of LEDS (2) and
(3).This function allows the technician to check
the combustion parameters. After the checks
deactivate the function, switching the boiler off
and then on again.
