This is from an Amazon review: The Wi-Fi feature requires more power than the usual wall thermostat, so additional power is required. Unfortunately, thermostat wiring frequently does not have a wire for power, or "c-wire." If you don't have a powered c-wire, your options become not-so-easy. You must run or connect a c-wire to your HVAC system, or buy a 24v wall plug and strip the wire at the end of that, plugging into the c-wire terminal (this means your once tidy wall thermostat will have a power cord running down to an outlet). If your eyes start to glaze over in technical incompetence at thought of either of these options, you may need a professional to assist. We had a c-wire installed for tidy appearance by a pro for about $50. Installation, not too easy, but it worked.

I've owned this unit and have installed it for other friends who didn't want to pay the price of the Nest. The first thing you need to know is it will not work without a C wire. Easy way to check is pull out your current thermostat and if you see a blue wire it's most likely your C wire. That wire is needed cause it provides enough power to get the wifi module working. Like a previous poster said you can run a power adapter to compensate if you don't have a C wire (many youtube videos how to do it). Another thing to note even if you DO have the wire it may not be connected at the HVAC unit, that was the case for my friend so we climbed the attic and attached it to the brain. Very important to always shut off the breaker to your HVAC system or run the chance of blowing a fuse.

My opinion of the unit itself if you don't already have a wifi thermostat you'll love it. Looks wise my wife didn't care for it and we ended up getting a Nest thermostat. It's very similar to the thermostats you see alarm companies will install. The great part doing it yourself is its a lot cheaper and you don't pay any monthly fees for them to "monitor" it.

If you don't have a C wire and want a wifi thermostat Nest will work for you because where this unit requires the additional power to have the wifi working, Nest uses a trickle charge to its internal battery which makes have a higher compatibility percentage. Nest display only turns on when you walk by it or physically using it so it's able to get away without the C wire, with the 3M-50 like most traditional thermostat the display is always on.

Hope that helps anyone wondering if this will work for them.
Good information. Does anyone know about these followup two questions

I have the following unit currently installed with backlight: http://www.homedepot.com/Heating-...reId=10051 Does this mean I have the so called BLUE (C) wire?

Is there a way to know if the BLUE (C) wire, if present, is connected to the HVAC without going through the attic? Thanks

I bought one of these last summer for $99 -10% coupon but had to return it because it wasn't compatible with the geothermal heatpump system I had installed. It is a 2-stage heat pump with 2-stage auxiliary electric so I needed a stat that would handle 4 stages, which the 3M50 does not. I had to spend nearly $300 on an Ecobee instead. I think the 3M50 is a great value if it is compatible with your HVAC system.

So other than the ability to remotely operate, is there any advantage to replacing current old gen thermostat with this?

Just trying to figure out if it is just a convenience thing or there are other factors. I know it reminds Air filter change etc., but that I manage by an a to do note on my phone
It's a 7 day programmable thermostat so you can set every day to have a different setup. I'm not sure what type of older thermostat you have - it'd be a big improvement over a non-programmable one, but might not be much better than a weekday/weekend programmable.

It might be true if your house spends more time in the "high" temperature than the "low" temperature, but that is not recommended if you want to save money. Most people program them so that both during the day when at work, and during the night when asleep, the temp is down (when in heating mode) so that its only really working for an hour or so in the morning and 3-4 hours at night. The rest of the day (the other 19 hours) it should be maintaining a lower temp, and that will save you money. People who try to "Debunk" energy savings typically have an agenda (and a gun rack in their truck). Ask them for proof.

Here is a great article (with references): http://www.getrichslowly.org/blog...ave-money/
this is true... I forgot I live in the south where the temp is usually 55 at the lowest... seldom reaching freezing.

My honeywell thermostat does something called "recovery" where it makes the central come on well before scheduled time to achieve the desired temperature for the scheduled time... My bill is still low enough... setting my thermostat at 65 only in the mornings when im getting ready for work and 60 for the rest of the day... but for the majority of the day even in winter the temperature here is.... close to 60 so I don't know how often it kicks on and off.

I currently live in an apartment and think I will stay in this unit for another 1.5 years. Do you think it is worth the hassle to install and uninstall it? That easy?
Personally, I'd buy a cheaper programmable unit for that. You can get them on sale for $30 all the time. The unit they are talking about here would be a little more complicated to install as it seems to need
an additional power supply, a standard programmable is practically plug and play since it hooks right up to the existing wires. Yeah, I'd get a regular programmable for your apartment definitely.

All remote access features require working WiFi network with internet access and a "C" or common wire connected to the thermostat for power
Anyone know what this means? The last part I'm talking about. Do most modern thermostats hace this common wire present already?
You need a blue wire coming out of your wall in order to power the thermostat. Most homes built since 2005 should have this. Just take off your current thermostat and check for the presence of a blue wire. If it's not there - you can buy an AC adapter that plugs into a usual power outlet on one end. The business end of it will go into where the blue wire normally would. Heres an example:

Ha, yeah me too and once it is programmed I never touch it. I can't think of too many reasons I would need to have it on wi-fi remote control. Although, it would be pretty funny to mess with my wife by turning the heat down remotely when I'm not home. Smilie



Wow, that would be nice. Here, we end up paying around $20 a month just for "hookup" fees and taxes! Sometimes these fees are almost is much as the actual Gas Charges! When I asked the gas company why
these fees were so high, they told me the fees are the only way the company makes money and not on the actual gas charges themselves.

Yeah i get pissy in the summer when they charge me the "minimum" charge of like $10 when I didn't even hardly use gas... my state is poor so everything's relatively cheap utility wise. Only thing thats gas is hot water and central... and i live alone.. so yeah.

Slickdeals is completely stupid.

I work from home, I rarely go anywhere, and when I do I'm with my wife and am not allowed to turn the thermostat down because the "dog might get a chill". And I already have a 7-day programmable thermostat that I never use because I programmed it badly and so now I just use the hold feature and its set to permanent 78F.

And yet, I just ordered one of these things.... how is this place saving me money?

I would die at 78 degrees, summer or winter... that's hot. crank it on down to 68, she'll never notice!

How much is your monthly gas bill for that temp?

I have one of these and I have been happy with it. Here is a forum that is associated with the STAT, maybe that will answer some questions. http://forums.radiothermostat.com/

Looks like any negative reviews are about setting up the wifi. If you can get around that (call customer service) looks like the thermostat works great. Still in for one.
