- Set the system's main switch to "off"
- Unscrew the fixing screw of the connections cover, then remove it
from its seat by pulling toward you
- Undo the fixing screws of the shell
- Move the housing base forwards and then upwards to unhook it
from the frame
- Lift the control panel and successively turn it forward
- Loosen the screw of the pressure test point downstream from the
gas valve by roughly two turns, then connect the pressure gauge.
The CALIBRATION & SERVICE operations must be performed
with the boiler in the off position. To do this, press the
key
until you see "ENERGY FOR LIFE" on the display.
During the parameter modification operations, the
key
acts as an ENTER key (Confirm), while the key acts as an
ESCAPE key (Exit). If no confirmation is given within 10 sec-
onds, the value is not stored and the previous one is indicated
again.
Setting the "programming access" password
- The programming of the parameters is accessed by pressing the
key and then pressing the
key for 3 seconds.
- PROG appears on the display followed by CODE.
- Press the ENTER key to confirm.
- Enter the adjustment code by rotating the encoder A until the nec-
essary value is reached.
- Confirm the adjustment code by pressing the ENTER key.
- The programming access password is located inside the command
panel.
Setting the "Combustion analysis" password
The programming of the parameters is accessed by pressing the
key and then pressing the
key for 3 seconds.
PROG appears on the display followed by CODE.
Press the ENTER key to confirm.
Enter the adjustment code by rotating the encoder A until the neces-
sary value is reached.
Confirm the adjustment code by pressing the ENTER key.
The programming access password is located inside the command
panel.
Calibration stages
The CALIBRATION & SERVICE phases scroll in sequence by turn-
ing the encoder:
01 type of gas (do not modify this parameter)
02 boiler output (insignificant parameter)
03 degree of insulation of the building (only displayed if an external
probe is connected)
10 DHW mode (do not modify this parameter)
45 thermoregulation curve inclination (only displayed if an external
probe is connected)
47 2CH thermoregulation curve inclination (only displayed if an ex-
ternal probe is connected)
HP maximum fan speed (do not modify this parameter)
LP minimum fan speed (do not modify this parameter)
SP ignition speed (do not modify this parameter)
HH boiler at maximum output
LL boiler at minimum output
23 maximum heating electrical value adjustment
24 minimum heating electrical value adjustment (do not modify
this parameter)
Parameters 2 - 10 - HP - LP - SP - 23 - 24 must only be modi-
fied by professionally qualified personnel, and only if absolutely
necessary.
The manufacturer declines all responsibility if the parameters
are incorrectly set.

MAXIMUM FAN SPEED (P. HP)
- Select parameter HP.
- Press the ENTER key to be able to modify the parameter value.
The maximum fan speed is linked to the type of gas and the boiler
output - table 1.
- Turn the encoder until the desired value is reached
- Confirm the new value by pressing ENTER.
Modify this parameter only when absolutely necessary.
The value is expressed on the display in rpm/100 (e.g. 3.600 = 36).

MINIMUM FAN SPEED (P. LP)
- Select parameter LP.
- Press the ENTER key to be able to modify the parameter value.
The minimum fan speed is linked to the type of gas and the boiler
output - table 2.
- Confirm the new value by pressing ENTER.
Modify this parameter only when absolutely necessary.
The value is expressed on the display in rpm/100 (e.g. 3600 = 36).
The value set during this operation will automatically modify the max-
imum value of parameter 24.
