Thermostat for new heating system

I have an Aprilaire which works well except for the fact that the buttons were attached to the back of the faceplate using something called "hopes and wishes", and I had to reattach them all using Krazy Glue. But the thing works well.

A good thermostat has the name "Honeywell" on it. Avoid the ones printed with "Lux"

:-) Okay, I'll go with the Honeywell Vision Pro 8000. Is that good? I almost bought a Lux, so it's a good thing I read this message.

I don't need to buy a special thermostat to support a high efficiency heating system, do I?

Thanks, PB

If a heating contractor couldn't answer these questions, I'd quickly find another contractor.

If I was getting that unit, or any new heating system I would be asking the manufacturer and my instaler whats best and how it works. Your "pro" did a wriiten heat load calculation for you, im sure. Because you will not need nearly as big a system as you have now, and to get maximum comfort and efficency you want it sized right, not by the guessing game method. You really need to contact York, you "pro" should have gone over everything with you.

It sounds like any series 80 (2 wire low voltage) thermostat will work

I know that Rheem Contours need their own stat. As to yours, discuss that with your installer.

Well, he just said any thermostat would work and he thought the ones I already had would be fine since they are programmable.

I didn't ask him how these things work...

Well, he took measurements of the entire house. I'm assuming he picked a size that works, but how can I tell? He seemed to know what he was talking about, because he said the unit in the attic shouldn't be high efficiency because the attic gets cold. He also noted that the current attic unit is on the attic floor and he recommended hanging the new one from the roof (joists?).

For our downstairs unit, he didn't recommend going with high efficiency at first. I asked for him to give me a quote, and the incremental price was less than the tax credit. So...

The guy I chose was the one that did the calculations and showed me the paperwork, he was suprised a much smaller unit would work, as no other contractor bidding realised because they were just guessing on Btu, it allowed me to use a smaller cheaper unit and save a bit. I added alot of insulation so I knew I needed a smaller unit, what I had was to big and heated me up to fast making me uncomfortable so Btu was cut in half. I guess your attic freezes so you have to put in a non condensing unit for the second floor? To bad you cant just use one unit that 98% york will save you alot over a 83% non condensing unit. Honeywell and White Rogers, make quality. Lux and other off brands are not tops. Be sure you get the 10yr warranty, some offer 15 yr as extra, get it if you can. You have alot of expensive components that may not make it. The VSDC motor has had problems supposidly a redesign has cured.

Hi, No 'stat included with the new furnace install.? Can't go wrong with Honeywell brand. If I were you, I'd have 10 year P&L warranty for that furnace. Some parts are very expensive.

Hi, I have Vision Pro 8000. It has couple different model. Like single stage, double stage heating, etc.
