New Trane broken already

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

With a heat pump as a back up, yes. Gas alone, no.

Hmmm.

For some reason, I think your right. Now I got to go look.


You were right I was wrong.

So the thermostat may be wrong too ?

Do you know the full model # you got? If you got the TH4110, it can be used. but it won't fire 2nd stage as needed, the timer on the board will do that, and lot of us don't like that..

But if it's TH4210, then it won't work, unless you have a heat pump set up with your furnace.

Yea, 2 stage furnaces on timers don't have the ability to provide the comfort like a thermostat controlling it would give.

Single stage heat single stage cool. They are going to run the second stage off the furnace boards timer.

When did they say they will be back?

Well after replacing the limit switch it still tripped , he also removed the ducting to prove to me it wasn't a restrictive venting issue . The service tech believes it is a burner issue . I spoke to the owner of the outfit he promises complete satisfaction , they are replacing the furnace and will re-evaluate the sizing . If I want a different thermostat (tech felt that the thermostat was a good one) , they will also get whatever I want (any recommendations?) It seems to be being handled as professionally possible . Except for possibly having the wrong size furnace. They will advise me on Monday the details . Trane is being called by the company.

Since this Trane stopped, tell them to give you a Westinghouse 95% 2stg with VS motor.

Like i said, Westinghouse makes the brakes for Tranes(trains).

Did he remove the supply and return ducting?

A Honeywell TH5220 digital non programable, or a TH6220 digital programable thermostat.

If you need more then a 80,000 BTU 90% I'll be suppirised.

Where are you? What's the house like? More than normal amount of windows? No insulation? I'm with been, still suspicious on sizing.

As I pointed out, Sis has a 75K 92% on a 2 story house about your size. Ducts in the crawl, leaky windows, decent insulation. At about -5° it will run constantly, might start to lose ground about -10° out but that's once every 10 years or so. She got a test furnace - I had a choice of 75K or 120K and wasn't about to go the monster.

I would certainly request the 2 stage thermostat wired properly instead of crippling a great furnace with a timed 2nd stage.

Removed supply and return . Looking for a programmable thermostat .

Honeywell 8000 series.

touchscreen programmable.

You can go to the IAQ if you want. Thats the macdaddy. If not, I would tell them to put in a TCON803. Thats the Trane number for the Honeywell 8000.
