•
Adjust the minimum pressure with the screw "E", clockwise to decrease it and anti-
clockwise to increase it.
•
Reconnect the faston detached from the modureg on the gas valve.
•
Check that the maximum pressure has not changed.
•
Refit the protection cap "D".
•
To terminate 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. 4.1). 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. 4.1).
Lighting power adjustment
To adjust the lighting power, switch the boiler to TEST mode (see sec. 4.1). 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. 4.1).
User interface
The user interface is developed on display cards
DSP05
,
DSP06
or
DSP08
, which com-
municate with card
INTERF_U
via a flat cable.
If replacing the card
INTERF_U
, in order to manage the display card
DSP08
, a parame-
ter must be changed.
This occurs by pressing the and Summer/Winter buttons together for 5 seconds.
Service menu
The card is equipped with two Menus: one for configuration and the other defined Service.
The configuration Menu is accessed by pressing the DHW buttons together for 10 sec-
onds. 2 parameters, modifiable only from card, are available.
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.
"In" -Information menu
The card can display the following information:
Press the Heating buttons to scroll the list of information. In case of damaged sensor, the
