## Stairway lighting function

The channel works as stairway lighting and automatically switches off after the *Activation Time*.  
It is activated via the ***Switching*** KO.

During runtime, a new switch command can:
* Be ignored,
* Restart the timer, or
* Extend the remaining time.

Optionally, the light can dim down before switching off using a *Follow-up time*, and switching off via KO can be blocked.
