IGNITION
With the boiler in stand-by mode, (after having checked that the chamber is clean), press the key
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 procedure 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 functioning,
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 auto-
matically 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, going to
power level 1.
The output water temperature can be increased by pressing the key
The display alternatively shows the desired temperature and the power which is automatically chosen by the electronic modulating
system.
ECONOMY FUNCTION
This is suitable for boiler installations in small systems, where functioning at minimum power would give excessive heating in
any case.
This function, managed automatically, switches off the boiler when the set output temperature is reached. The wording "EC OF"
will appear on the display, indicating the minutes remaining before shut-off.
When the output temperature has fallen below the set value, the boiler will automatically switch on again. This function can be
requested from the technical assistance centre when the boiler is switched on for the fi rst time.
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.
