In order to use it as a 2 wire stat, you need the EIM.

That picture is of a wireless outdoor sensor and a comfort remote. I hope! See the description of the item, it describes the part numbers of everything that comes in the kit.

Good point! I've gotten so used to the sound of those relays now.

True, except with redlink wireless stuff, you don't need wired sensors anymore. Although I think wired sensors have the advantage of never requiring batteries to be replaced.

I'll have the same setup (gas furnace with electric heatpump) any complaints about going with the Prestige? was it easy to wire and setup?

It will arrive next week. I'll let you know how it goes!

It's quite similar to the TH8320 with a few more bells and whistles. Because I feel like I know so much about the TH8320 now and how it is wired and configured, I don't suspect the Prestige will be very challenging.

The standard IAQ uses wired sensors.

You'd be surprised at how many people hate that clicking noise.

You may think that using the stat without the EIM is easier to wire, but as you wire the whole system you may find that it is NOT easier to wire all at the stat.

I missed this post before, Are you saying that the IAQ or Prestige can't control the variable speed blower? (meaning, its either on or off? not low or high?) If so, is it a big deal? (never had forced hot air before, only baseboard) what other blower settings do you mean? Is this typical of all manufactures (you need to use their T-stat to get full control) or only goodman? The furnace is coming in tomorrow so I guess I cant change that now, haha.

it is not that big of deal..... IMO

you can still control it on and off, just not up and down.

Just ordered the Prestige 2.0 IAQ, with EIM 2 duct sensors, Wireless outdoor temp sensor and Internet gateway. All for $391 shipped! Now for the real fun.. the install! I have a HVAC tech installing the furnace and heatpump, but I don't think hes installed one of these before. Hopefully between the 2 of us we should be able to get it rigged up. Thanks for all the help folks!

Goodman's communicating stat does all of the furnace set up. using any other stat, the furnace has to be set up by the dip switches.

It typical with any communicating furnace or blower.
