Thermostat Recommendation for 95% furnace


I recently purchased a Goodman 115,000 BTU 95% Efficiency, Two Stage Burner, Variable Speed Blower, Upflow/Horizontal Application Gas Furnace.

http://www.acwholesalers.com/Goodman...ce-p/11140.htm

I haven't yet installed it and need to figure out which thermostat to get. I've been looking at this one: http://www.amazon.com/Honeywell-TH83.../dp/B000WTG03A

But I'm concerned that one of the reviewers said that it tries TOO hard to keep the temperature steady and that it comes on and off too much or something.

I need a two-stage thermostat, fully programmable, touch screen and compatible with high efficiency variable speed furnaces.

Can anyone make any recommendations?

THANK YOU SO MUCH!

That thermostat is a great one! If you prefer for there to be more swing in the temp. then you have the ability with that t-stat to program it as such You will be very pleased with that furnace and I would expect you would seldom hear it run anyway. If it runs too often there is probably a heat loss problem in your house you should address.

What he said

That is a great thermostat and you can alter the swing if needed.

Go for it.

I appreciate the feedback, but some of you guys gave me bad advice and it cost me $80. This thermostat doesn't have a swing adjustment. Now I need a new thermostat.

Did you check the specs on the thermostat before you bought it?
While I ask for opinions too, the ultimate decision is mine

You got me. Do you feel better now? But, I do genuinely apologize for my error. I was confused. I personally deal with several different stats and I did get that one mixed up. I am very sorry.

Interesting attitude though. btw....that was the first time I was ever wrong

It is still one of the best stats on the market. And how on earth did you get one for $80? I want to buy from there.

No problem, people make mistakes, life goes on. I'm trying to adjust the CPH down to 2 which I'm hoping may help. I'm just tired of it cycling so often.

I got it on ebay, here: http://cgi.ebay.com/ws/eBayISAPI.dll...m=290290732242

Thanks for the response. I guess you already know this:

Why does the system come on early to reach the set temperature?

The thermostat is equipped with a feature called Smart Response or Adaptive Intelligent Recovery. This feature takes the guesswork out of achieving a comfortable temperature at the exact time you desire. When this feature is operational, you will see "IN RECOVERY" in the thermostat's display, and the room will reach the comfort temperature at the time programmed into the thermostat. In heating for instance, if the NIGHT program is set for 11pm at 65F (18C), and the MORNING program is set for 6am at 72F (22C), the thermostat will turn the system on before 6am to bring the temperature up to 72F (22C) by 6am. The thermostat learns from experience, so please allow approximately two weeks after a program change or after initial installation to give Smart Response time to adjust to local weather, your lifestyle, the construction of your home and your heating and cooling system. Smart Response works the same way in cooling. If the DAYTIME program is set for 8am at 85F (29C) and the EVENING program is set for 5pm at 75F (24C), the thermostat will turn the system on before 5pm to bring the temperature down to 75 (24C) by 5pm. The thermostat learns from experience, so please allow approximately two weeks after a program change or after initial installation to give Smart Response time to adjust to local weather, your lifestyle, the construction of your home and your heating and cooling system.

Chet,

Are you using the new stat with the new furnace?
If not, you might find its operation perfectly acceptable when the new two stage
furnace is running in low stage, which it should run most of the time.

No one gave you bad advise.

You didn't say you want a 2 degree swing.

If you give specs on what you want, then you get advise that is closer to being 100% accurate.

Did you read about CPH, and setting more aggression, and less agression.

Also, you said you already read about its tight temp control.

You get a 2 stage furnace for tight temp control.
