Operation of wall devices

Operation of digital wall device SDW 30
A digital wall device SDW 30 can be connected to the control
device.
With a digital wall device, remote control for a central device (e.g.
from a living room) is possible in addition to the room temperature
detection. Settings can be carried out for all the existing heating
circuits.
The bus address of the wall device is used to specify the heating
circuit on which the room sensor (room influence) is to act.
When an SDW 30 is connected for the first time to the bus
system, the address is selected for the heating circuit to which the
SDW 30 is to be assigned (bus address).
After the input has been confirmed, feedback of the heating circuit
(DC, MC1, MC2) and the central unit (CU) to which the digital wall
device has been assigned is output.
Assignment is carried out on the basis of the following table:
