LTE mode
LTE mode was specifically designed to simplify engineering. Unlike with S-mode, there
is no need to create the individual connections (group addresses) in the tool. The
devices autonomously establish connections.
In order to make this possible, the following circumstances are predefined:
•
Every device or sub-device is located within a zone
•
Every data point (input or output) is assigned to a zone
•
Every data point (input or output) has a precisely defined "name".
Whenever an output and an input with the same "name" are located in the same zone,
a connection is established automatically, as shown in the following diagram.

The following types of zone are defined:
•
"Geographical" zones (Syntax:
Apartment . Room . Subzone
).
The timeswitch zone is a "geographical" zone used for special purposes
•
Outside temperature zones
•
Heat distribution zones
For further details, refer to the Konnex specification.
