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 establish the connections themselves.
To make this possible, the following was defined:
•
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 time-switch zone is a geographical zone used for special purposes.
•
Outside temperature zones.
•
Heat distribution zones.
•
Refrigeration distribution zones.
For further details, refer to the Konnex specification.
