New home owner, I assume it is for my air circulation system but unsure how to use it to the best of its abilities. Does More Humid make the house more humid, or should I turn it to that setting when the house is humid to negate it?
Crawl up into your attic or wherever the air circulator is installed and find the exact model number of your unit. See if instructions can be found here: https://web.archive.org/web/20160603194940/https://vanee.edenenergy.com/res-air-exchangers-literature.php
If not, I would contact vanEE directly. I had to use the Wayback Machine as the documentation section on their current site is blank.
Awesome, 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.
It looks like a combination humidifier/dehumidifier as well as an outside air exchanger.
The air exchangers are nice as you can run them when the air outside is very cold or very hot, as they will retain a large portion of the interior air temperature, despite swapping your interior air for outdoor air. That specific feature seems like a sometimes thing, when you wouldn't normally have windows open for awhile, but you do want fresh air that day.
