This logic group switches on one of two lighting circuits alternately with each switch-on operation in order to distribute the operating hours evenly.

The ON/OFF input alternately activates and deactivates the TOR elements.
For switching on, the binary filter tool only allows the ON telegrams, which are changed again and again via the toggle tool. This is necessary to activate and deactivate the two TOR elements in alternation.
To switch off, the OFF telegram is routed past the TOR elements directly to the two outputs.

To avoid superfluous OFF telegrams on the KNX bus, a binary filter tool is inserted in front of each output that only allows changing values.
