Connecting the remote control
The remote control device communicates with the central
controller via the eBus. They can be connected to any
interface in the system. It simply has to be ensured that
the bus interfaces are eventually connected to the central
controller.
The structure of the Vaillant system allows you to lay
the eBus from component to component. This means that
the wires can be swapped without impairing
communication.
