    If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.

    If you do know, then do. But do it right. Otherwise, you may not be doing it long.

    He doesn't he loses money when he has to change it to a smaller one. He sized by the previous equipment size, and lost.

    Not knowing the age of the home and other info, I would almost want to bet you could get by with a 80,000 model.

    Ask for a manual J, and if you want, you can down load a home owner's manual-J up above for $50.

    All the stuff you got on there, sure hope they did a two stage t-stat???

    Man, do you have a problem

    First off, I think we can be safe in concluding your furnace is over size

    second, you say the returns are two--14 x 8 and a 6" ???

    a 120K BTU furnace will move 2000 cfm. On a furnace this big, I would install a MINIMUM of 10 x 24 in a bottom return or two 8 x 24, one on each side of the furnace. I think your return is inadequate.



    NOW.....not all is lost. The TUY120R9V5V can handle a 3½ ton air conditioner. Increase your return air to, two 24 x 8 (24 x 10, if it will fit) and--->

    check your dip switch's, I would set them up this way for 3½ tons of a/c~~~~~

    1st stage heat, DIP SWITCH 7 & 8 to NORMAL
    . sw7---on, sw8---off. with a static pressure of 0.5 this should give you a fan speed of 1370 cfm with a delta T of 49° (for *HI* speed set them to sw7---off and sw8---off)

    2nd stage heat, DIP SWITCH 7 & 8 to NORMAL. sw7---on, sw8---off

    AIR FLOW SETTING FOR COOLING

    DIP SWITCH 1 & 2 & 3 & 4 (set the fan speed to 350 cfm/ton)
    sw1---off, sw2---on, sw3---off, sw4---on ~~~~~ with a static pressure of 0.5, these setting will give you 1220cfm.

    If you set the dip switchs to 400cfm/ton the minimum fan speed you will get is 1400cfm

    You have a heat pump on this set up?? This stat is for a heat pump, and if you have a heat pump, I'd ask for the Honeywell IAQ to get a MUCH better control of the heat pump, and stage the gas furnace.

    But before you do that, we got to fix this "maybe oversized" furnace.

    I saw that after I posted, and there is the TH4210 that is for heat pump.

    We don't know off hand of what model he may have.

    Come to think of it, he may very well have the TH4110 being he said the furnace locks out after 10 min... The board is firing off 2nd stage around that time.

    Plus, I believe the 4210 can be used on fossil fuel fnaces. Like the 5220 can.
