feeding with a MM67, new install

So I finally have a boiler with a MM67 and I need to feed it, anyone have a good-better-best way to do this? A few weeks ago I had issues with overfilling and @Steamhead gave me some tips. This is a little different- when i set up the TDC should i just change the circuit to 24V and do a 24v feeder? Running a TDC with line seems more cumbersome. Thanks for any comments

    If the 67 is wired 120V, I'd use a VXT-120, add the necessary switched wire back to the junction box and run a 3-wire BX cable from there to the VXT.

    Ok cool so yes or no on the time delay? Or, is it the SG400 that requires the TDC?

    I think I’m confused. A few weeks ago it was new style low-water cut off with oldschool Feeder, this time it’s old style LWCO with the new feeder. Got it. I’m making it more complicated than it is thanks for the advice
