Default home thermostat: are HD's as good as anywhere else?

Or do they have their own ****ty ones, made by name
brands but expressly for HD?

If HD is bad, then where?

Thanks!

David

My personal opinion: if it doesn't pass quality control, send it to HD. I
buy Honeywell and White-Rogers from Grainger.com

I've used a couple of Honeywell from their and they've been working
perfectly for a number of years. Lux is supposed to be lesser quality so I
avoid them.

For programmable thermostats, the difference is probably very very
small. The thermometer in most is probably a simple piece of Chinese
silicon. Add an integrated circuit, and voila. A perfectly good piece
of electronics. Lifetime: about as long as any other lump of
integrated circuitry with no moving parts, which is to say about
forever.

Maybe in the past there was a difference in the metallurgy of the
mercury-driven spring coil, but all that variation and cost has been
engineered out.

Hi,
Made in China stuffs are all made on different specs. Compare Honeywell
and say Hunter thermostats. Open it up and look inside. Feel the buttons
for human interface. I had to replace quite a few Hunter, Noma, etc.
cheaper thermostats at my relavies'and friends'. They usually last until
warrant runs out. I use Honeywell Vision Pro touch panel 'stat and
wireless one which never gave trouble since installed. Just reelace
batteries when it's time to replace them. Maybe you have not worked in
the field of QC for screening source material? If you think an IC being
sold at RS and one from industrial whole sale house is one and same,
WRONG! If it is mil-spec'd one, then that is again different category.

Any Honeywell you buy at any store is a fine product. The pricier ones
are better performers according to experts in the field. So go ahead
and buy the top tier at any store you like and get on with your next
important project with that muck less to worry about,. HTH

I can tell you that all the major brand stats are made outside of the US these
days. They aren't very complicated and the components all come from non-US
countries anyway.

I had some Lux stats that developed a contact issue where corrosion over a
couple of years got to the point that the stat did not see a change in the
rotary switch position. I'm not convinced that that was a problem unique to Lux
though.

And if you think Honeywell or any other stat manufacturer is buying mil-spec or
even industrial spec components for their stats, you would be very wrong... Even
if they were (they aren't), those specs mostly relate to harsh environment
(vibration, temperature, salt fog atmosphere, etc.). None of those apply to the
typical household environment and none will extend the life of a component.

Furthermore, no manufacturer would buy "seconds" or QA fail components to
populate production devices. They'd fail product QA or the retailer/distributor
returns would quickly put the company out of business.

It is quite common to use "seconds" in manufacturing. Where this is most
common is in electronic component manufacturing. There will always be a
range of quality in any production run. Stuff that doesn't meet the
first quality spec is labeled as some other quality and sold off or
used to make a cheaper version of a product (often the big box version).

Just be wary of anything in a big box with a non-standard model number
(unique to that store chain). Sometimes this is just done to make
comparison shopping harder but other times it is a "reduced cost" item
that might be lower spec.


Also so you can't match and beat prices White Rogers have never let me
down

Hi,
When you mentioned extending the life of a electronics comonents. then
what would be the main factor determining it's life? Silicon components
will last 20 years plus under normal operating condition. Even there is
a mil-spec. soldering.
