Application "1-button switching" as primary function
NOTE
This application can also be activated as primary function via "Primary function".
The device has a primary function. This is the first function of the device which is carried out
when the user actuates button 1 or 2. The primary function should be a function that the user
would use when entering the room for example (e.g. "switching the ceiling light".
Only the following application can be defined for the primary function:
■
1-button switching
When actuated and/or released a switching telegram is sent out. In each case, the application
makes a separate set of parameters and communication objects available for the 1st and the
2nd button. The other side of the button can be assigned a further "button-oriented" function.
