In the upper half of the display, there are different ways to show the controller function.  

A text describing the controller, for example, can be entered in the "

Labelling (control function)

field. 

Status display

 

Here you determine whether only the current setpoint (in large letters) or the setpoint and actual 
value (in small letters) are to be displayed.  

Symbol 

With this selection, either the "Heating/Cooling" operation or a "HVAC" operation mode can be 
displayed. All symbols can also be individually set in colour. 

Display control value 

When activated, the current setting value can be displayed here via a bar symbol. This is a purely 
visual display, not a numerical value. On the other hand, the control value can be shown via the 
colour of the "Heating" or "Cooling" symbol. 

Symbol für Eco/Night mode 

According to the KNX specification, this is the same operating mode. It is defined here which 
symbol is displayed for this operating mode. According to the selection, the displayed text for 
"Symbol colour for Eco" or "Symbol colour for Night" changes in the parameters below. 
 

4.2.4  User-defined colours 

 
Up to 3 user-defined colours can be mixed: 

 

Figure 7: Display settings 

 User-defined colours 

The user-defined colours can be mixed with the corresponding red / green / blue share and then be 
used for the display of the symbols.
