Art. No. SC 1000 KNX
4.2.4.1.12 Channel function "setpoint shift, internal"
With the channel function "setpoint shift, internal", the room temperature controller integrated in
the device can be activated, whereby it is possible to shift the current temperature setpoint
gradually within a specified range. No direct bus telegrams are generated by this channel
function. Status messages of the controller can only trigger bus telegrams.
If this channel function is used, the user can influence the room temperature control on the
control section in the room and thereby specify the temperature setpoint without switching over
the operating mode.
A KNX channel "setpoint shift, internal" has a display element and sensor surface in the graphic
interface for operation. The display area and sensor area, depending on the existing operation
concept, are combined into one surface (direct operation) or distributed on two surfaces
(selection operation). The sensor element is always executed as a rocker function.
Pressing the sensor surface
+
shifts the current setpoint temperature value by one level in
positive direction. Pressing the sensor surface
-
shifts the setpoint by one level in negative
direction. The setpoint can be shifted by several levels by pressing a sensor surface repeatedly.
A shift by a maximum of 4 levels is possible. The value of a level corresponds to 0.5K.
Consequently, the setpoint temperature value can be shifted within the range -2K...0...+2K.

The controller function must be switched on in the "Room temperature control (RTC)"
parameter node in order to use the channel function "setpoint shift, internal".

Status elements
The display area contains different display elements (figure 46) that are influenced by ETS
parameters. A name can be assigned to each KNX channel in the ETS (A). This text name is
centred in the display element for display whereby controllable KNX functions are identified for
the user (e.g. "setpoint").
In addition, a status value (B) can be displayed below the name. The status value displays the
