    Gas furnace with a heat pump thermostat

    I could use some advice.

    This past summer I bought a house. The house has a carrier gas furnace and a/c unit. The previous owner or possibly the builder installed a heat pump thermostat. I'm having an issue with it. I'm hoping someone can help.

    Whenever the heat kicks in, after a short while, the thermostat decides to kick in the auxiliary heat. Since its a gas system, I don't have aux heat, nor a heat pump. When it does this, it has the result of turning off the gas heat, leaving the system to just blow cold air. It does this until I turn it off, then turn it back on again.

    Is there anyway to work around this so that the thermostat never kicks in the aux heat? I'd like to avoid buying a new thermostat but if I must than I will.

    The thermostat is this one: http://www.residential.carrier.com/p.../premium.shtml

    If I must replace the thermostat with a new one, how do I know if my system is a 1-stage or 2-stage heating system? Does it matter for which thermostat to buy? The house was built in 1998, so the system isn't terribly old.

    Any help would be appreciated.

    i would

    check that you dont have a h.p., just to be sure. If so it may have issues that are keeping it from working. If its not a h.p. try to run it in emht position on the t,stat. I have had customers buy h.p. stats on adn they have to run them in the emergency heat position
    If you build it they will come,,,they built it and they went.

    Best to have a contractor out to install you a new and proper thermostat. There no other good way around it.
    Unless you are about to sell this house and trouble to another person

    Even the heat pump version of that thermostat can be used on a non-heat pump system if properly configured. I suspect you may have other problems than the thermostat. A heat pump stat should not bring on your furnace to begin with. Call a professional to check your system and setup, you will be dollars ahead to do so.
    If all else fails....Try reading the directions!

    Tell it like it is and let the chips fall where they may.

    Any views or opinions stated here are strictly my own.

    Your Tstat needs to be configured for gas and not H/P. Have a service company reconfigure for you. It is a good stat.
