Chapter 7 Display, LEDs and buttons
This section is applicable to Corrigo units with display and buttons but also to the hand terminal E3-
DSP which can be connected to Corrigo units without display and buttons.
Room units are available with or without display, or as a touch display (see instructions and product
sheets for ED-RU..., ED-RU-D... and ED-TCV).
7.1 Display
The display has four rows of 20 characters and is backlit. The illumination is normally dimmed, but
is activated as soon as a button is pressed. The illumination will be dimmed again after a period of
inactivity.
7.2 LEDs
There are two LEDs on the front: The alarm LED marked with the  symbol. The “write enable”
LED marked with the  symbol.
The four LEDs placed next to the upper terminal strip will be described later.
7.3 Buttons
There are seven buttons: four arrow buttons which will be called UP, DOWN, RIGHT and LEFT.
The menus in the Corrigo are organized in a horizontal tree structure. The UP/DOWN buttons are
used to move between menus at the present menu level. The RIGHT/LEFT buttons are used to
move between menu levels. When changing parameters the UP/DOWN buttons are used to
increase/decrease the value of the parameter and the RIGHT/LEFT buttons to move between digits
within the parameter.
 The OK button is used to confirm the choice of a parameter setting. See more in the section
"Change parameters" below.
 The C button is used to abort an initiated parameter change and restore the original value.
 The ALARM button, marked with a red button top, is used to access the alarm list.
7.4 Navigating the menus
The choice of access level/user access determines which menus are shown in the menu system.
The start display, the display normally shown, is at the root of the menu tree.
