I'm sure that what you are saying makes perfect sense to you, but I unfortunately haven't a clue what it is that you want to do.
Here's what I (we) need to know:
What interlock and what for?
What's the relay and transformer for?

...and you almost always need a neutral.

What in the world does a bathroom fan have to do with all these controls.

He is probably in Canada and trying to interlock the bath fan with a HRV so they both can't run at the same time.

Joed did hit the nail on that one and also I have did see that in Wisconsin as well so it is not specfically in Canada anymore due more and more homes are getting air tight so with exhaust fan kick on for some reason they will have to turn on the air make up unit ( sorta like heat exchanger but draw fresh air in )

Joecaption.,

It getting more common to see new home are more airtight and we just start doing that in European side as well.

Merci,
Marc

Very interesting. I would think the manufactures of the make-up units should include a pressure switch so people didn't have to do this hacky wiring.

You would have to run the cable to the vent fan or pull a new cable with neutral to your switch.
