Adjustment of pressure at burner
Since this unit has flame modulation, there are two fixed pressure values: the minimum
and maximum, which must be those given in the technical data table according to the
type of gas.
•
Connect a suitable pressure gauge to pressure point
"B"
downstream of the gas
valve
•
Disconnect the pressure compensation tube
“H”
and remove the protection cap
“D”
, undoing screw
“A”
.
•
Operate the boiler in
TEST
mode.
•
Set the heating power to 100.
•
Adjust the max. pressure with screw
"G"
, clockwise to increase it and anticlockwise
to decrease it
•
Disconnect one of the two fastons from modureg
"C"
on the gas valve.
•
Adjust the min. pressure with screw
"E"
, clockwise to decrease it and anticlockwise
to increase it.
•
Reconnect the faston detached from the modureg on the gas valve.
•
Check that the maximum pressure has not changed.
•
Reconnect the pressure compensation tube
“H”
.
•
Refit the protection cap
“D”
.
•
To end the
TEST
mode, repeat the activation sequence or wait 15 minutes.

Heating power adjustment
To adjust the heating power, switch the boiler to TEST mode (see sec. 3.1). Press the
heating buttons fig. 1 (details 3 and 4 - ) to increase or decrease the power (min. = 00 -
max. = 100). Press the RESET button within 5 seconds and the max. power will remain
that just set. Exit TEST mode (see sec. 3.1).
Lighting power adjustment
To adjust the lighting power, switch the boiler to TEST mode (see sec. 3.1). Press the
DHW buttons (details 1 and 2 - fig. 1) to increase or decrease the power (min. = 00 - max.
= 60). Press the RESET button within 5 seconds and the lighting power will remain that
just set. Exit TEST mode (see sec. 3.1).
Service menu
The card is equipped with two Menus: one for configuration and the other for Service.
The configuration Menu is accessed by pressing the DHW buttons together for 10 sec-
onds. 2 parameters, modifiable only from card, are available.
If replacing the card, always set the parameter P01 to 0=Copper.
To exit the configuration Menu, press the DHW buttons together for 10 seconds.
The card Service Menu is accessed by pressing the Reset button for 10 seconds. Press
the Heating buttons to select "tS", "In", "Hi" or "rE". tS” means Transparent Parameters
Menu, “In” Information Menu, “Hi” History Menu, and “rE” History Menu Reset. After se-
lecting the Menu, press the Reset button to access it.
"tS” - Transparent Parameters Menu
The card is equipped with 24 transparent parameters also modifiable from Remote Con-
trol (Service Menu):
Press the Heating buttons to scroll the list of parameters in increasing or decreasing or-
der. Press the DHW buttons to modify the value of a parameter: the change will be au-
tomatically saved.
The Max. Heating Power and Lighting Power parameters can be modified in Test Mode
(see relevant section).
Press the Reset button to return to the Service Menu. Press the Reset button for 10 sec-
onds to exit to the card Service Menu.
