3.11 KNX communications
The RDF KNX thermostats support communications as per the KNX specification.
S-Mode Standard mode; engineering via group addresses.
LTE Mode Logical Tag Extended mode, for easy engineering,
is used in conjunction with Synco.
3.11.1 S-Mode
This mode corresponds to KNX communications.
Connections are established via ETS by assigning communication objects to group
addresses.
3.11.2 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.
To make this possible, the following circumstances are predefined:
∂ Every device or subdevice 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.
