Electronic pellet burner controller – NPBC-V3C-2 /  NPBC-V4C-2

The controller has different types of menus. The examples below explain these types and the way to
set the parameters in each of them. Regardless the menu type, if no buttons are pressed for certain
time, the controller goes back to the previous screen or to the main screen. After adjusting the
parameters according to your needs, press the Menu button (

) to save your settings.:

List choice – A red bar indicates the currently selected row. Press the up or down navigation

buttons (

▲ or ▼) 

to move the bar and the right navigation button (►) to confirm the

selection. An arrow pointing down at the bottom of the screen or up on the top of the screen
indicates that there are more options in the corresponding direction outside of the visible area
of the screen. In this case, press the corresponding navigation button to go to the next or the
previous page. If there is an arrow pointing right on any of the rows on the screen, there is a
sub-menu with list choice again. While looking at any screen with parameter settings, press the
left navigation button to go back to the previous screen with list choice.

Parameter setting screen – At the moment when such a screen is displayed, a pink frame 
marks the first editable parameter. The left and right navigation buttons (◄ ►) move the 
frame to the previous or next editable parameter. The up and down navigation buttons (

▲ 

) change the currently selected parameter's value or put/remove a check sign. The 

parameter's type could be any of the following: editable numerical value, list with text 
values or check box that activates/deactivates a certain function. The numerical parameters 
are restricted in certain range of values. When the end of the range is reached, the value 
stops changing, despite the remaining sound signal for pressed button.
