A general limiter function can be selected.
15.2.1 Activate function
To activate this function, an input must be assigned.
If several other influences simultaneously act on the general limiter, priority order
as described in section 11.1.3 "Priority of functions" applies.
The gen
eral limiter cannot be activated for basic type A, controller 1, as the supply
air limiter is available for that controller.
