4.4 Basic display
In the normal operating status, you can see the basic dis-
play in the display. The basic display shows the current sta-
tus of the boiler. If you press a selection button, the rele-
vant activated function is displayed in the display. If the dis-
play becomes dark, the light is first switched on by the first
press of the button. In this case, to trigger the button func-
tion, you must press the button again.
You can switch back to the basic display by:
– pressing the left-hand selection button and exiting the
selection levels
– not pressing any button for longer than 15 minutes.
Changes that are not confirmed will not be applied.
If there is a fault, a fault message will be shown instead of
the basic display.
From the basic display, you can directly change and read
the most important settings and information by pressing
the selection buttons.
The functions that are available depend on whether a con-
troller is connected to the boiler.
4.5 Operating levels
The boiler has two operating levels.
Operating levels for the operator
The operating level for the operator offers you the most
frequently used setting options that do not require any spe-
cial prior knowledge and displays the most important infor-
mation.
Operating level for the heating engineer
The operating level for the heating engineer must only be
operated with expertise and is therefore protected by a
code. This level is used by the skilled tradesman to adjust
the parameters for the boiler to the heating system.
