Btw guys, here's a sneak peak of the 2.0 diy hrv unit I'm currently working on.
Featuring two centrifugal EC brushless fans, 650m3/h each, post heating radiator, homemade countercurrent 600mm heat exchanger, freecooling bypass damper and fresh air exclusion damper, all of them driven by 5V step motors. And of course the arduino Mega.
Stay tuned!
