Comment on What is this control for and how do I use it?
Millennial_Falcon@lemmy.world 1 week agoAwesome, did more digging and it turns out it’s an HRV and likely not something I need to be running during the summer months as I don’t need more warm air circulating and we keep windows open often enough to naturally exchange the air.

An HRV tempers the incoming air with the air going out no matter the season. So, in winter, it recovers some heat from the exhaust air and exchanges it with the cold intake air, keeping heat inside.
In the summer, it’s the opposite. The exhaust air cools the hot intake air, keeping the heat outside.
It’s essentially always working for your benefit (except for one edge case that I can expand on if you’d like), always providing fresh air and exhausting stale air while helping to keep the interior temperature where desired.
I’d recommend keeping it on all the time, no matter if you open windows or not.
