The One To One component models routing between one thermal port and a vectorized multiple thermal port.

The number of nodes of $\mathrm{multi\_port}$ can be set using the $\mathrm{Nodes}$ parameter.

According to the order list defined by the parameter $\mathrm{Select} \mathrm{Node}$, only a selected $\mathrm{multi\_port}\left[i\right]$is connected to one other port.  

The following image illustrates the behavior of the One To One routing component in the case of $\mathrm{Select} \mathrm{Node}$=2.
