in the diagram you gave after switching on, the differential would be crashed (if it was), because you short-circuited PE and N in the socket.
Well, that's the main question:
1.what we have installed on the wall?
2.what is the device cable terminated with?
Ad.1
Nest
Ad.2
Plug
According to my drawing, there cannot be an RCD. And according to you, maybe. Mistake
You draw a chemistry from right to left, which makes the drawing unreadable, and should be drawn from left to right. Error next.

where do you see the separation and reconnection?
With a 5-wire-plug (TN-S) installation, you connect the PE conductor to the N in the plug and continue to make a 4-wire-socket connection (TN-C). Mistake.

It comes out of the PEN socket and in the device it splits into N and PE.
Not. Not in the device, but in its plug. And that's a big difference.
Because the request is this:
artmel wrote: Please present the connection method a 5-pin plug to a 4-pin socket , and conversely.
And without a piece of wire, a 4-pin plug and a 5-pin socket, I don't see the possibility of doing this.
And next:
artmel wrote: ... and conversely.
And here I agree that:

Keep misinterpretation of the drawings to yourself.

ps. I need this transition, because at work I have a 5-pin socket and at home I have a 4-pin socket and I have a car that starts poorly in winter, so I use the 380V starter (and he has a 5-pin plug ).
Then he writes:

For clarity:
