Since recuperators or heat recovery ventilation units are very expensive plus none has all the features I want, I decided to build one on my own.
Electronics will be done with arduino and additional sensors, if you are interested I will describe it in detail later. Heat exchanger will be aluminum counter flow,purchased for about 200$. Housing is also not a problem. I stucked with buying some affordable centrifugal EC fans...

Hello Damo,
I'm very interested in your fan controller and your whole heat recovery project. Please let us know how your project is proceeding.
I am working on a similar project, also using an Arduino to control the fan, and the controller part of that project can be found
HERE.
Used high efficiency centrifugal fans can be found on ebay
HERE.
I was able to find very good EC fans at a very good price on ebay, you just have to keep coming back and looking.
Good luck on your project.
Sincerely,
