the parameter scrolling speed is increased.
To confirm a change in parameters, press ENTER for at least
3 seconds. A change in the parameter is indicate by the display

•
From the initial screen (ON/OFF/rdy/FXX) use the ↑ (up arrow)
and ↓ (down arrow) keys to reach the ABI function; hold down
the ENTER key for 3 seconds;
•
Set the password inside the ABI menu and confirm it with
ENTER; hold it down for approximately 3 seconds (the
flashing display will confirm that the parameter has been
stored);
•
Press ESC and, by using the ↑ and ↓ arrow keys, return
to the initial screen (ON/OFF/rdy/FXX); press ENTER for

To exit the parameter and the menu, press ESC until the
initial screen is displayed (ON/OFF/rdy/FXX).
4.2.4. Level 1 menu
The first level in the menu consists of the following items:
1. machine status: ON, rdy, OFF;
2.
FUn
, it allows to force the ON, OFF operation type; this menu
can be accessed only in case of Stand-Alone configuration
(ModBus address equal to Ø); when the address is different
from Ø, this menu cannot be accessed;
3.
rEg
, it allows to force the burner at minimum (Lo) or maximum
(Hi) output in order to perform combustion tests;
4.
tin
, it shows the input voltage value (0/10Vdc) if the boiler
is connected to a cascade management control unit;
5.
PrA
, it shows water pressure inside the hydraulic circuit. It
is used to load, and to control, the pressure inside the boiler
and the hydraulic circuit. If the 01.6 value is displayed, the
pressure inside the circuit is 1.60 bar;
6.
Abi
. Entering the second or third level password allows to
switch from the Abi menu to the underlying menus.
7.
FRC
allows to operate the circulator manually. Selecting
the key for 3 sec will provide access to BLO submenu.
Pressing the UAR key (up arrow ↑) starts the circulator.
Releasing the UAR key (up arrow ↑) stops the circulator.
N
ote: To display water pressure value, press Enter when
PrA is shown.
4.2. LCD instrument panel
The instrument panel is fitted with a red 3-digit LCD display and
with four function keys:
↑
,
↓
,
ESC
and
ENTER
;
The screen allows the user to display the boiler operating mode,
the Faults, water pressure inside the hydraulic circuit and the
reading of probe values.
It also allows the service centre to change the main operating
parameters.
Changing parameters requires a password.
4.2.1. Viewing the machine status
The machine status is shown on the display by the following
wordings:
rdy
the machine is on without burner flame, it is waiting for the
ON control and/or the heat demand from the thermostat
On
the machine is on with burner flame on;
OFF
the machine has been switched off through the LCD
control; any heat demands will be ignored. To light the
boiler, the LCD must show the wording "operation ON";
Fxx
Fault detected.
During normal operation, the display will show the wording
On
if the burner is on;
rdy
when the boiler is being switched off or
the room temperature has been reached.
If the boiler is connected to a SmartEASY/WEB, the PCB address
must be set to a value different from Ø. In this case, every 30
seconds and for the following 5 seconds, the display shows the
PCB modbus address as Axx, where xx is the programmed address.
In the event of communication problems between CPU-SMART
PCB and LCD panel, the word
CPU
will flash on the display if
the problem is caused by the CPU; three flashing dots will be
displayed if the problem is caused by the display PCB.
If needs be, check that the display and the PCB are correctly
connected and that the small cable RJ11 is securely held in
the connector.
4.2.2. Menu Navigation
The menu has three levels and all levels can be accessed in
display mode. The first is accessible without entering a password,
the second and third require entering passwords in write mode,
as described in paragraph 4.2.5.
With modbus address other than Ø the following SETS can be
edited: ST1, ST2, ST5, ST6.
If the boiler PCB is connected to a SmartEASY/WEB, and
therefore with an address different from Ø, parameters can be
viewed but cannot be modified.
The Service Centre that is required to use all menus must follow
these instructions:
- disconnect the power supply;
- set the PCB address to Ø;
- restore power;
- after finishing the work, please remember to reset the switches
to the previously set position.
Use the arrows to scroll the menus: UAR (up arrow ↑) and DAR
(down arrow ↓). Press ENTER to select the menu, and again
to select the parameter. Change the parameter with the arrows
and confirm the change by pressing ENTER.
To exit the parameter or menu, press ESC. If you exit the
programming function, after about 10 minutes the program
will exit the menu and go back to the "machine status" display.
To change the parameter, press the arrow keys: pressing UAR
↑ increases the parameter by 1, pressing DAR ↓ reduces it by
1. When the arrow keys are pressed for at least three seconds,
