Change-over of the operating mode using KNX communication objects
A distinction is made whether the operating modes should be changed over via separate 1-bit
objects or, alternatively, by the 1-byte KNX objects.
The "Operating mode change-over" parameter in the "Room temperature control -> Controller
general" parameter branch specifies the switching method as follows.
- Operating mode change-over "Via switching (4 x 1 bit)"
There is a separate 1-bit change-over object for each operating mode. Each of these
objects allows the current operating mode to be switched over or to be set, depending on
the priority. Taking account of the priority, a specific hierarchy will result from the operating
mode change-over by the objects, a distinction being made between presence detection by
the presence button (Figure 26) or the presence detector (Figure 26). In addition, the status
of the window in the room can be evaluated using the "Window status" object, meaning
that, when the window is open, the controller can switch to Frost/heat protection mode,
irrespective of the set operating mode, in order to save energy .
Table 5 also shows the status of the communication objects and the resulting operating
mode.
