Which wires go where

Would anybody be kind enough to please explain to me which wires on my current wireless receiver connected to the boiler go in which section of the Google nest wireless receiver?

I would be eternally grateful I’ve included an image of my current one, and an image of the Google nest (current Neomitis)
