### Central functions

The central functions are used to define lamp groups that can be controlled together.

When a central function is enabled, the KOs for ***Switching***, ***Relative dimming***, and ***Absolute dimming*** of the central function are released, allowing multiple channels to be controlled simultaneously.

Which lamp group a channel should belong to is defined in the ***Central functions*** tab of the respective channel.  
A channel can be assigned to multiple lamp groups/central functions.
