    Hi Sal,

    Most fireplaces we have encountered have an RF remote - is yours controlled by a separate thermostat or something else?

    Most natural gas fireplaces I have seen operate on a low voltage thermopile and either a battery powered or bimetallic passive thermostat.
    Is there a way of adding a generic heat source, which is not controllable by Flair?
    I'm guessing the control algorithm would work better if it had all heat sources. The fireplace is substantial, with an output of 24,000 BTU/hr for 600 sq.ft in the basement living room.

    Hi Sal,

    The simplest way is to create a new Thermostat in the system and make it of type 'Other'.  It will have a zone associated with it.  Any rooms that substantially draw heat from that fireplace/thermostat could be considered to be in the zone of that thermostat, if it only really heats that one room, then the zone can also just be that room. I'm not sure if it will help anything for your system as I don't know what else you have in the house but generally its best that the hvac systems in the house and how they work is configured and documented in the app.

    Cheers,
    Dan

    Hi Dan,

    My apologies, perhaps I should expand more. My home has central hvac (furnace + ac), I have 8 smart vents and 2 pucks split evenly between the basement and main floor. All vents get their air from the furnace. We have a gas fireplace in the basement that is manually set to 72 F.

    Thanks for the reply. If I create a new 'Other' thermostat it asks me how many vents there are in this zone (minimum 3 vents error). The fireplace doesn't have any vents. Its just in the room as a heat source. I don't want to assign vents to the proposed 'Fireplace' zone, as this is not reality. All vents get their air from the central hvac (Nest thermostat located on main floor).

    My thought is that we need a generic heat source object.

    Thanks for the added context/clarification - setting the number of vents on that thermostat (to make the error alert go away) shouldn't interfere with the operation of the other vents so long as the zone associated with the fireplace doesnt share rooms with the central hvac.  From what you said - split evenly - I'm guessing that the room that the fireplace is in also has vents?

    Hi Dan,
    Yes, the fireplace is in the basement. The basement also has central hvac vents. Most homes which have gas fireplaces also have hvac vents in the same room.

    My basement has 4 smart vents, 1 puck, 1 natural gas fireplace.

    Hi Sal,

    I ran this by the engineering team and their recommendation was to simply not document the fireplace in the app actually.  Their main point was that the vents should operate correctly regardless of heat contribution from the fireplace thus there is no need to add it.  If after removing it from the Flair, you still have questions or are hoping that the vents will do something differently, I'd suggest shooting a note to the support team as they can take a look remotely and make recommendations.

    Cheers,
    Dan
