Replacing thermostat circuit board in a Taco 006 with a 5 wire fan capacitor?

Your post title implied you were removing the thermostat circuit board and replacing it with a 5 wire fan capacitor ONLY !!!

" I'm adding a relay unit with C wire to enable a smart thermostat, and one way to do it is pull the board from the Taco and replace it with the relay, but I still need a starting cap. "

OK, so what you wrote the board goes away and an unknown relay is added with a 5 wire fan capacitor.

No transformer original or replacement was mentioned. What would you expect a thermostat that was connected to that situation would do ???

I have know idea what your electrical knowledge and skill level is, and what you wrote made little sense to me and apparently others.

BTW (not that it matters) I've repaired and tested many VFDs, from fractional to over 100 HP, I get how the tech works.

I'm still under the impression only you condone what you did and how you did it.

It's always so nice to have a vastly superior intellect telling us knuckle dragging types how stupid and backwards we are. Thanks, @Jells
