autonomously performs a cycle at minimum power “P0”,
ignition “P1” and at maximum power “P2” to obtain good flame
stability, then goes into mode CO2 modification to allow manual
calibration.
The setting of the type of mode (AUTO or MANU) is entered in
the activation code for parameter “P14” in the TSP Parameters
menu.
TSP parameters that can be set from the interface and from the
Remote Control.
The AUTO mode is the recommended one and which allows the
greatest freedom to modify the CO2.
OPERATIONS TO BE PERFORMED
Enter the chimney sweep function and check that the CO2 value
is within the limits of Table 11 both at maximum (Hi) and minimum
(Lo) power (if the system temperature rises excessively, it is
possible to open the DHW cocks to dispose of the heat; it is not
possible to start the procedure with the DHW open).
If not, proceed as described below.
Press the keys simultaneously for the cycle time “ MODE ” and
“ RESET ”. Release then immediately (within 2 seconds) press one
turn the button “ ”.
The card confirms the activation of the function and shows on
the display “ Au-to ” or “ Ma-nu ” depending on the defined setting
mode.
The board will internally generate a request for operation in
“calibration” mode and will start the power-up sequence.
If the function is active “ Au-to ”, the flashing of the “ radiator ”
symbol is also activated.
Once ignition has been completed, the boiler will perform a
parameter storage cycle at maximum power, then at ignition
power and, finally, at minimum power.
During this phase, the LCD display cyclically shows the cycle
time and the flow temperature.
At this point, the flue gas analyzer probe can be inserted into the
exhaust duct.
4.7 ADAPTATION TO THE USE OF OTHER GASES AND ADJUSTMENT OF THE BURNER
The boilers are produced for the type of gas specifically
requested when ordering, which is shown on the packaging
plate and on the boiler technical data plate.
Any subsequent transformations must be carried out
strictly by qualified personnel, who will use the accessories
appropriately prepared by the manufacturer and will carry
out the modification operations and adjustments necessary
for a good set-up.
4.7.1. TRANSFORMATIONS FROM METHANE TO LPG
Change parameter P02 from 0 to 1.
Affix the label indicating the LPG regulation on the boiler.
Check and if necessary modify parameters P08, P09, P31,
P32 and P33 in accordance with the indications in the Table of
parameters.
ACCESS PARAMETERS
Simultaneously pressing the keys for the cycle time “ RESET ” And
“” You enter the parameter programming mode.
The message “tS” appears on the display for 1 sec, then the P
number of TSP for 1 sec and then the value for 3 sec.
The first modifiable parameter corresponds to P01.
By pressing the keys “ ” o “ ” select the desired parameter.
By pressing the key for the cycle time “ ” the modification
function of the selected parameter is enabled. The previously set
value appears on the display.
By pressing the keys “ ” or “ ” the value of the selected
parameter is changed.
By pressing the key for the cycle time “ ”the new setting is
stored. Simultaneously pressing the keys for the cycle time“ RESET
” and “ ” you exit the parameter programming mode.
Proceed with the adjustment of the combustion (CO2).
4.7.2. TRANSFORMATIONS FROM LPG TO METHANE
Change parameter P02 from 1 to 0.
Affix the label indicating the CNG adjustment on the boiler.
Check and if necessary modify parameters P08, P09, P31, P32
and P33 in accordance with what is indicated in Table 24.
ACCESS PARAMETERS
Simultaneously pressing the keys for the cycle time“ RESET ” and“ ”
you enter the parameter programming mode.
The message “tS” appears on the display for 1 sec, then the P

The first modifiable parameter corresponds to P01.
By pressing the “ ” or “ ” key select the desired parameter.
By pressing the key for the cycle time “ ” the modification
function of the selected parameter is enabled.
The previously set value appears on the display.
By pressing the keys “ ” or “ ” the value of the selected
parameter is changed.
By pressing the key for the cycle time “ ” the new setting is
stored.
Simultaneously pressing the keys for the cycle time“ RESET ”
and “ ” you exit the parameter programming mode.
Proceed with the adjustment of the combustion (CO2).
4.7.3. CHECK AND ADJUSTMENT OF THE GAS VALVE
PREMISE
The boiler, by means of the “BEST” function, automatically
adapts the combustion according to the installation conditions,
therefore the following procedure must be carried out following
the chimney sweep function if the gas calibration values do not
correspond to those on the plate or if the electronic board, the
electrode, the fan or the gas valve have been replaced.
The boiler must be ready for operation, purged of air and with the
heating function enabled.
The procedure can start in two different modes depending on the
value of parameter “P14”:
AUTO (“P14” = 5): the boiler performs 10 ignition attempts at
gradually increasing powers;
MANU (“P14” = 0): the boiler performs 5 ignition attempts at the
ignition power indicated in parameter “P31”.
Once the burner has been successfully ignited, the boiler
