If using loosely compressed pellets, you could select:
LEVEL 0
:
is an operating program that decelerates the speed of the smoke suction unit when using loosely compressed
pellets and/or when the flue outlet has a very high vacuum, over 2 mm water column (20 Pascal).
The pellet consumption value remains unchanged regardless of the selected operating level. These variations will only change the
rotation of the smoke suction unit in the WORK stage (see para. 6.10), all the other stages will not undergo any changes.
Select the required Level by acting as follows:
1) Press the
Menu Button
three times quickly and the following box will appear:
After a few seconds the following screen will appear on the display:
2) To change the operating level, hold down a
Scroll Button
while simultaneously pressing the other
Scroll Button.
To set the desired level simply press the
Menu Button
several times until the initial screen will appear on the display.
The level selection can be made with the appliance
OFF
or
ON
. If the change is made while the appliance is running
the difference in the flame will be apparent. It is mandatory to pay particular care when selecting the most appropriate
operating cycle for your installation. After the selection of the operating cycle a thorough cleaning of the brazier is
mandatory.
6.6 THERMOCONTROL: CONTROLLING A PUFFER
The appliance must be energised and the I/0 switch in position “I".
This function enables you to control the operating temperature of a stratification puffer through the use of two sensors PT 100
(optional) connected to the respective terminal block on the electronic board (see dedicated paragraph).
ATTENTION:
If one or both optional sensors are not connected to the appliance or are interrupted, it will not be possible to view
and therefore activate the THERMOCONTROL function.
When this function is activated the appliance automatically controls the ON/OFF cycles based on the activation temperatures set by
the user.
The puffer must have an appropriate capacity. We recommend a capacity ranging between a minimum of 20 dm
3
to a
maximum of 50 dm
3
for every kW of maximum power supplied to the water by the appliance.
The THERMOCONTROL function can be activated in the following way:
1) Quickly press the
Menu Button
until the following screen appears:
After a few seconds the following screen will appear on the display:
2) Press one of the two
Scroll Buttons
and the following screen will appear (Select ON to activate).
3) Confirm the selection by pressing the
Degrees Button
and the following screen will appear:
4) Press the
Scroll Buttons
to set the activation temperature for Sensor S2. Sensor S2 is installed in the top part of the puffer
and it commands the appliance to start up as it is exhausting the available heat inside it. The setting range is between 40 °C
and 65 °C.
5) Confirm the selection by pressing the
Degrees Button
and the following screen will appear.
6) Press the
Scroll Buttons
to set the activation temperature for Sensor S1. Sensor S1 is installed in the lower part of the puffer
and it commands the appliance to shut off as the puffer is satisfied. The setting range is between 60 °C and 70 °C.
The settable temperature will in any case always exceed, by at least 4°C,the temperature setting for S2.
7) Confirm the selection by pressing the
Degrees Button
then press the
Menu Button
several times to exit the screen, until the
initial screen appears.
At this point the appliance operating status will appear on the display.
