RoBo that's hilarious, Here you are giving all this great advice on all the latest hvac equipment and you run window units?

I've got a similar system and it's great except I'd use a true 3 stage tstat. The vision pro won't control the back up rather relies on the furnace's control to time it in. I think white rogers has a...

Anyone recommend an install contractor near Nassawadox VA?
Job involves installing Ductwork, AH and conpmressor.

Wont work for 3 stage if 1 is HP and 2/3 are gas. Ask me how I know. You need a different Tstat or use the 2 stage setting and let the furn. hickon hi @ 10 min. Or get a white rogers which supposedly...

Good reason to have pre-season checkout, Couldn't you fire up the aux and for the a/c to melt the coil?

On the plus side if you or your contractor has a problem
you can ask RoBo!

Deep down you know what to do, If #3 treata you like this before he even has a contrct how do you think it will be after he's cashed your check, Don't they have any other rheem dealers? I had a...

I had a GMV90 installed and as someone stated earlier
it's really hard to know if the fan is on in circ mode.
According to the lit. they left with me the blower is
56% of the high stage cooling. ...

I keep lowering mine. Started at 40 dropped to 35,30
now @ 25 in st. louis. 2 story 8"cement block with 4"
brick. New windows and 8" blown in attic. Was down to
20 last night so gas finally...

had a Goodman 93 variable speed w/ 3.5t HP w/90/60 2 stage aux heat installed last month.
Just got my electric bill $65 w/434 degree days
compared to $50 w/0 degree days last month. Tstat set @ 68....

Yeah thanks that's where the confusion is and the work around seems to be an external relay.
That or go with the white roger 371 I think. Funny
I posted asking for people to compre the two and...

That figures jultzya, so how about stage three? which is gas stage 2. So far the closest thing I can see is just set the VP to 2 stage and let the furnace time from low to high output.The Vp...

Do you have a squirrel in the squirrel cage blower?

yeah that'll work, Run the call for stage 1 HP through NC
contracts. Have the call stage 2 through coil and NO contacts to W1 on furnace. Call stage three straight to W2 on furnace. You would think...

OK so can you say how it, namely the VP would be used with a 2 stage fossil back up? They have aux and emergency terms.
Y is first srage (HP), second is Aux? or is it put Y2 on
first stage of the...

that's a thermister not a tstat

OK. You would think the firmware would keep that test
from being available with Single stage chosen as option
during setup. Is the white rogers 3 stage a better choice?
Or does that need to be...

I have read that the vision pro 8321 is a 3 stage t-stat
however there seems to be the opinion that it can't be used on 1 stage
heat pump w/2 stage fossil back-up.
I like the technology of the VP...

Thanks the honeywell looks awsome hopefully functional and durable as well. Anyone on have experience with White Rogers
they make a 3 stage also. ...

I am planning on getting the system replaced in my home Currently 4T a/c and 100btu old nat gas furnace.
I've seen people talk about duel fuel which is the way I think I should go here in Missouri....
