Close all vents in basement

    Hey JB,
    When you set up your flair system, you enter in the total number of vents, and the total number of flair vents connected to that furnace.
    Flair simply divides this out, and only allows 1/3 of the vents to be closed to prevent over-pressurization of the system. Keep in mind that if you manually partially/close vents, you should also make sure of the same.


    My understanding is that in the app, each furnace is supposed to be set up as a separate "home".
    Each thermostat gets its own "zone" in flair (  in your case e.g. [2 zones for home1] and [1 zone for home2]  )
    Each "room" is controlled by one puck and any number of vents (i.e. my entire basement is one "room" with 3 vents).

    If you would like to override the 1/3 rule, you can set the total number of vents to whatever you like. Just be mindful of the reason for the rule.

    Flair does not require a separate home for each thermostat/zone, unless you want to run each system in different modes.

    Flair recommends keeping Back Pressure protection active.

    Thanks,

    @...

    I see, thanks for clarifying. This thread reply by Flair Support states that each furnace should have its own "home" set up inside the app IF you want independent control of the systems.

    Sal - generally we recommend a single home for most users.  The rare exception is cases where within a home you want to run a zone in heat and another in cool simultanously.  You might even be able to do that in auto with a single home in the event that the flair mode is set to auto although I honestly can't quite remember.  Generally its quite unusual but not unheard of to need to run heat in some places and cool in another.  The most common scenario we see is AirBnBs, hotels, etc.  Great suggestion above on the total number of vents - the 1/3 rule assumes everything was sized conventionally but if a contractor or homeowner added more supply registers then you can definitely adjust that slider to meet your needs while still keeping some back pressure protection in place.

    Thanks for all the responses. Finally - I purchased Keen back in the day when it came out and I returned it because it didnt close completely. Does flair close completely or do I still need to use the magnetic covers when the basement is not in use?

    I don't have a % off hand but if I had to wager a guess it would be something like 99.5%. There are very slight ~.5mm tolerances around where the louvres meet the frame to allow them to close without running into tolerance issues at manufacturing.  I'm guessing its a tighter than the keen vents but I haven't really looked at those closely.

    I would say more like 90%, Flair smart vents are very leaky when "closed."
