4.2.4.3.3 Display functions

Indication of the controller operating mode
The controller extension can indicate the current operating mode of the controller in the display.
Just like on the controller itself the operating mode is indicated by the 0 (comfort), 1
(standby), 2 (night) and ¾|4(frost/heat protection) symbols. A comfort extension cannot be
shown in the display if the controller status is configured to "KNX compliant". When the status is
"Controller general", then it is possible to display a comfort extension.
This display information of the controller operating mode is obtained from the status
communication objects of the controller extension. These objects should be connected to the
main controller objects with the same function (see page 167)!
It is not possible to use the display information to distinguish whether the operating mode has
been set via a forced object or via the 'normal' operating switchover. It is possible to change
over the operating mode using the control function of the controller extension (see page 171).
Display of a basic setpoint shift
When 2-area display is configured, the controller extension can indicate a basic setpoint shift
using the z icon. This icon lights up if the controller extension has received from the controller
a basic setpoint shift in the positive or negative direction. In addition to displaying the icon, the
push button sensor indicates the setpoint shift in the "Setpoint" menu even for controller
extensions (see page 18-19). How it is shown there depends on the parameter setting in the
ETS: either with a temperature value (absolute depiction) or using a bar graph (relative
depiction). If the setpoint shift is depicted in the form of a bar graph, the shift is also visible in the
normal display (see page 182).
In order for the display of a basic setpoint shift to function correctly, the communication objects
"B.Main controller current setpoint shift", "B.Controller extension setpoint value specification"
and "D.Input set temperature controller extension" must be connected with the objects with the
same functions in the main controller (see page 167)! A basic setpoint shift can be set using the
operating function of the controller extension (see page 172-173) or in the "Setpoint" menu.
i The display function "Setpoint shift" is only available on a control extension if the main
controller is working with relative setpoint presetting (basic setpoint). In the case of an
absolute setpoint shift on the main controller, it is not possible to display a setpoint shift on
the controller extension.
Indication of setpoint temperature
The controller extension can indicate the setpoint temperature of the room temperature
controller in the display. If this display is desired, then the communication object "D.Input
setpoint temperature controller extension" must be linked to the object of the main controller via
which the setpoint temperature is transmitted to the bus. In addition, the display of the extension
must be configured for the indication of the temperature setpoint (see page 182).
i Regardless of the indication on the display, the current setpoint temperature of the main
controller is decisive for the setpoint shift on the controller extension. For this reason the
object "D.Input setpoint temperature controller extension" must be linked to the main
controller!
Indication of the heating and cooling messages
The main controller can indicate on the display that heating and cooling energy is requested by
the heating or cooling systems. This is indicated by the " 4 " symbol for heating or by the " ¾ "
