Electric Boiler Controller NELBC-1
General User Interface Guidelines
Controller's display has touch-sensitive panel over the entire screen area. The controller is operated
through a variety of settings menu screens. Depending on the type of screen and the type of
modified parameter a virtual digital or alpha-digital keypad, delete button, navigation buttons, etc.
appear on the right-hand of the screen. To "press" any of the virtual buttons, the corresponding
image of the button should be touched, preferably at its center in order to avoid the activation of
adjacent buttons.
When an active area of the screen is touched there is a short beep. When a button is pressed then it
"lights up". On settings screens parameter labels and other additional information are in green while
parameter's values are in white. Current field which is modified is framed and highlighted. When
the parameter is numeric then its value range appear in the field over the keypad.
When the currently entered value is outside parameter's range then the field's frame becomes red.
In this case, changing the focus to another parameter or quiting the screen results in long beep and
the parameter revert to its previous value.
Required parameter may be reached for modification by pressing buttons

, thus going
thtough all parameters in turn forward or backward accordingly. However it is much easier to
directly select the needed parameter by touching its "virtual area" where its value is displayed.
