I’m looking clarification on this “recirculation” feature listed for some of these VanEE HRV/ERV models. There is a chart on the site linked below, listing several Vanee models and there is a column marked “recirculation mode”. Then it says yes or no for which models have this.

I was a bit confused on this. I assumed every model has the option to exchange air for a certain amount of time in the hour and then recirculate the existing air. Assuming the house fan will just do that while the HRV takes a break.

So is that mode for like…when the HRV is hooked up to it’s own dedicated duct work? And needs move air on it’s own?

I also saw “recirculate exhaust air” mentioned as a DEFROST method, so maybe that’s what that is?
