solarbird | ambient-hvac air quality control at work

Oh hell yeah the air-exchange vent did the thing! It’s probably not the first time but I did just roll out the code over the weekend and it’s the first time I’ve caught it doing this:

log file output showing ambient_hvac noticing the air outside is better than inside from a 2.5nm ppm standpoint, and opening the air exchange vent to let outside air into the house filtered air circulation loop

What’s happening here is that the system is reporting that indoor air was lower quality than the outdoor air by enough points that even though the temperature directly was wrong, it activated the air-exchange for five minutes anyway to help with air quality. Then it closed it down again.

I probably need to fiddle with that buffer number – an indoor of 9ppm is still very good and could even have been a false reading and 4 probably isn’t better enough to care. And I don’t want to be stressing the air-exchanger. But this is all more testing phase so of course it’s going to be a little wibbly at times. I’m fine with that. What matters is: it’s working! 😀
