Art. No. SC 1000 KNX
- Operating mode change-over through "value (1 byte)"
There is a common 1-byte change-over object for all operating modes. During the running
time, the operating mode can be changed over through this value object immediately after
the receipt of only one telegram. In this connection, the value received will set the operating
mode. In addition, a second 1-byte object is available which, by forced control and through
higher level, can set an operating mode, irrespective of any other change-over options.
According to the KNX specification, both 1-byte objects have been implemented.
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 97) or the motion detector (figure 98). 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 .
The following table also shows the status of the communication objects and the resulting
operating mode.
