7.3.11.1 Bus address of central device
Control devices SDC and DHC 43 can be connected via a data
bus. This makes it possible
•
to control additional heating circuits by adding up to four
additional central devices.
•
to connect wall devices to the central devices and assign
heating circuits.
•
to cascade multiple heat generators with one built-in central
device each.
The following figure shows the maximum possible expansion
stage of the bus system.
The individual devices in the SDC/DHC 43 bus system contain a
unique address. It is set in the corresponding parameter in the
"Data Bus" menu. Assignment is carried out using the table
below.
