Default HRV systems

Hey guys, i need some assistance with HRV systems. Anyone know how many outlets/inlets does one floor need? Each room? Or is one in/out enough for the whole floor?

We have a bungalow style cottage that we want to add the HRV into, and it has a crawl space, and the main floor with 3 bedrooms.

Any information on these HRV systems is appreciated.

I understand that adjustments on these are touchy.

I thought so too.
Look at some links to these things. On at least one, differential air pressures needed to be fussed with.

Here's some generic stuff.

Skip the CLAIMS, the DESCRIPTION is the meat of this.
