Option 4 = Link room product connected to one or two main room products
It applies to most setups that they are delivered with the correct option
setting from the factory, and they are thus "ready for use".
However, since in some situations you may have to work with products
that have been installed before, e.g. in connection with a house that has
been rebuilt, the correct option is indicated at ALL illustrations, even
those which are "ready for use" from the factory.
NOTE!
If the option programming is not executed
correctly, a malfunction will occur.
