“HRV Arduino Controller with Air Economizer
So my history with this project is I live in Minnesota and my circuit board fried on my LifeBreath 155Max HRV. I didn’t want to pay the $200 for a new one.
I always wanted something with an air economizer since our springs and falls here are perfect times to take in cool low humidity outside air and condition the house rather than turning on the air conditioner or opening windows. This is where this project fits in.
I wrote up a detailed description of operation for all the modes, setpoint control, etc can be found here “HRV Control Narrative.docx”
All source code, photos, wiring schematics and documentation can be found on my GitHub page.”
