If the boiler and all the rest of it is brand new, and you wired it
together and it doesn't work right, guess what... It's probably your
wiring that's at fault.

You've posted no schematics, nothing about what the problem is other
than that the relay is buzzing, and nothing about what you've done
to isolate the problem, and yet you seem to expect us to pinpoint
the solution for you because you say you can't afford to have a
professional come in and do it properly.

What's wrong with that picture?...
