IGNITION
With the boiler in stand-by mode, (after having checked that
the chamber is clean), press the key
cedure will start.
On the display the wording "ON AC" (start combustion) will
appear; after certain control cycles and after checking that the
pellets are burning, the display will show the wording "ON
AR" (heating on).
This phase will last a few minutes, to allow the ignition proce-
dure to complete correctly and for the exchangers in the boiler
to heat up.
After a few minutes, the boiler will enter the heating phase,
indicating the wording "burn" and later, during regular func-
tioning, the temperature of the output water, set by the user, is
indicated and the power chosen by the automatic modulation
system.
SWITCHING OFF
Pressing the key , when the boiler is on, will start the
switching off phase, which involves:
• Stopping the delivery of the pellets
• Burning any pellets left in the chamber, keeping the fume fan
on (usually for about 10')
• Cooling the boiler's body while the pump remains on until
the shut-off temperature is reached
• The indication "OF" on the display together with the minutes
remaining until shut-off
During the switching off phase, the boiler cannot be turned on
again; when the switching off phase is completed the system
automatically goes into stand-by mode.
AUTOMATIC FUNCTIONING
The user must set the output water temperature, which must be
assessed according to the type and dimensions of the system,
and considering the atmospheric temperature linked to the
season.
The boiler automatically modulates power according to the
difference between the set temperature (set on the display) and
the temperature measured by the water sensor; on reaching the
desired temperature, the burner will function at minimum, go-
ing to power level 1.
The output water temperature can be increased by pressing the
key , or decreased by pressing the key
The display alternatively shows the desired temperature and the
power which is automatically chosen by the electronic modu-
lating system.

ECONOMY FUNCTION
Function suitable for boilers installed in small-scale systems, or
whenever minimum power operation causes excessive heating.
This function, managed automatically, allows for switching the
boiler off once the set delivery temperature is exceeded.
When the delivery temperature falls below the set value, the
boiler switches back on automatically. Request activation of
this function, if required, from the Technical Assistance Centre
during initial start-up.
When the ECONOMY function is activated, the display will
visualise 'Econ' after the other information.
REMOTE ACTIVATION FUNCTION
By means of a special connection wire (code 640560), the
boiler can be switched on/off by a remote control device such
as a GSM telephonic activator, an environment thermostat, a
zone valve, or in any case a device with clean contact with the
following logic:
Contact open = boiler off
Contact closed = boiler on
Activation and deactivation takes place 10" after the transfer of
the last command.
If the remote activation of the door is connected, the boiler can
be switched on and off in any case by the control panel; the
boiler will always act according to the last command received,
whether for switching on or off.
PLEASE NOTE:
If the remote activation function is used, decouple the remote
connection cable, using a relay, if the distance between the
remote device and the boiler exceeds the length of the cable
code 640560 (1.5 m).
Consult the instruction sheet of the connection cable for more
detailed information.
