    Hi Chris,

    Does this same phenomenon occur during the summer? Is your second floor also warmer than your first floor? If so, you have a combination of scenarios:

    When heating, too little airflow to the downstairs, too much airflow to the upstairs

    When cooling, too much airflow to the downstairs, too little airflow to the upstairs

    That will require Pucks and Vents in all rooms to circulate the air for maximum comfort seasonally.

    For more information, see this chart that explains the airflow scenarios Flair solves: Airflow Scenarios.

    To answer your question about back pressure protection, Flair will prioritize closing Smart Vents in Active rooms first. You can use a schedule to set rooms to Inactive when you're not using them so Flair concentrates on Active rooms. These articles explain more:

    All the best,

    I already have a Flair system installed on all my vents, but currently, it's set not to control the set point on my Nest primary thermostat. My question is about how it will behave if I switch to letting it control the Nest.

    We have a heat-only central heat system. Even with Flair pucks and vents in every room, it can't close enough upper-floor vents to get enough airflow to the bottom floor to make up for the drastic temperature difference.

    I've gotten around this problem sort of by having the Nest use a remote temperature sensor located downstairs for part of the day. However, Nest doesn't let you customize what time of day it uses the remote sensor, which causes several other problems I won't get into. It would be better if I could let Flair control the Nest based on which room is the coldest, but I also don't want a situation where the upstairs rooms get run up to 80F because of cold rooms downstairs plus back pressure protect, so my question still remains: how does the Flair set point algorithm deal with two wildly different puck temperatures? Will it keep running the heat until ALL rooms hit their set points, or is it smart enough to notice that it's causing some pucks to go way over temperature and balance the needs of all the rooms?
