4.2.2. Navigation Menu
The menu has three levels: the first requires no password while
for the second and third, a password is required.
If the boiler board is connected to a SmartControl and/or to
SMART.NET and the address is different from 0, parameters
are read-only and cannot be changed and some menus are
not available.
When Service Staff need to access all menus, they will have
to do the following:
- Disconnect the unit from power supply.
- Set the board address to 0
- Restore power supply.
- When done, remember to restore switches to their original
position.
To scroll menus, use UP and DOWN arrows. Press ENTER
to select the menu or the parameter. To change a parameter
value, use UP or DOWN arrows, then press ENTER to confirm.
Press ESC to quit. After 10 minutes from last entry, setup mode
automatically closes and the standard status display is restored.
Use arrow keys to change the parameter (UP arrow to increase
and DOWN arrow to decrease). If you keep the arrow pressed,
the speed increases.
To confirm the change, press ENTER for at least 3 seconds.
The display flashes to confirm the parameter was changed.
All submenus scroll from bottom to top.

4.2.1. Viewing the Equipment Status
The status of the equipment is reported on the display through
the following messages:
rdy
Means the equipment is powered but there is no flame
lit in the burner. It is waiting for an ON command and/or a heat
request from room temperature control.
On The unit is ON and a flame is lit in the burner;
OFF
Means the equipment was turned off using LCD control.
Any heat requests will be ignored. To turn the boiler ON, switch
LCD display to “Operation ON”
Fxx A problem (fault) exists.
During regular operation, the display shows
On
if the burner is
turned on, or rdy if the burner is turning off or room tempera-
ture is reached.
If a SmartControl and/or SMART.NET are installed, board ad-
dress must be set to a non-zero value. In such case, the modbus
address of the board flashes for 5 seconds on the display as
Axx, where xx is the configured address.
If the CPU-SMART board does not correctly interface with the
LCD display, CPU will flash on the screen if the problem is
with the CPU, or three dots will flash if the problem is with the
display board.
If so, check that the display and the board are properly con-
nected and that the RJ11 cable is firmly plugged in.
