Converted from an old Lennox to this with a two-stage heater and two-stage cooler. Determining which wires were which took a little time; even though they were labeled it took a little time to translate from Lennox call outs to Honeywell. Likely a non-issue for a HVAC person. Took about an hour of research on what the wires meant, and about five minutes of attaching wires to screw studs.

Best feature is the fact that it integrates with a Portable Comfort Control. This $85 remote has its own temperature sensor in it, so we can set the remote wherever it is we think we’ll get the best overall control. We mostly keep it on the main floor during the day and drag it upstairs at night. Best of all, my temperature sensitive wife can strap it to her hip and end all discussion on why it’s too hot/cold. :) Way worth the extra cost.

Only con is that you have to buy the $85 Redlink Internet Gateway to get a log of your usage. Other thermostats (like the Nest or EcoBee) have this built in. Honestly don’t think I’d use it after the first couple of weeks, but it would have been nice to have.


Excellent – Definitely get the Red Link Internet Gateway, January 2, 2014 (5 stars)

Works extremely well. Lots of customizations. Works with my Aprilaire 700 Whole House Humidifier. Only downside is it uses Red Link instead of true WiFi, so you need to purchase the Red Link gateway to connect to the Internet, but I strongly recommend you buy the accessory. I turn my system off from my iPhone while driving away from house and turn it back on 30 minutes before coming home. It’s nice saving money on heat and not walking into a freezing home. The software is flawless and well-made, just nervous like others that Honeywell may one day charge a fee. I also got the outdoor temperature sensor which is not really a necessity but it’s fun to see the temperature at your house in the morning or when you are far away, as the weather report might not accurately reflect your house. Overall, a really great product.

You do not need to be an expert to install this, although you do need a C power wire so you may need to run an extra wire if you happen to be using all the existing thermostat wires in your line.

I originally purchased Honeywell Wi-Fi Smart Thermostat from Home Depot and replaced it with this one. This is much more heavy duty version of that thermostat, with a lot more customization options and a better looking (albiet larger) casing. I would recommend this one over the ‘dumb downed’ version they sell as the DIY model any day of the week.

Watch out for “Smart Response Setting”, February 11, 2011 (4 star)

I had to replace an older cheaper Honeywell that decided it didn’t know what time of day it was.

I decided to go with this more expensive model– but I had reservations after having read some reviews and comments elsewhere where some people complained that the furnace was always on, or they were burning more oil or gas than before. . .

I found the reason–

It’s called ‘Smart Response Technology’

It’s ‘ON’ by default if you do the quick DIY install.

To turn it ‘OFF’ you have to download the FULL MANUAL from the Honeywell site to see how to get into the ADVANCED Settings of the device. The pamphlet you get in the package is just your BASIC setup.

I bought the programmable Honeywell to control my oil usage and keep the furnace from heating the house in the dead of the night when everyone is in bed. And I would set the Program to turn the Furnace ON and reset the Temp back to 70 degrees at 7 AM. In short– The Furnace turns ON at 7 o’clock and in time, (20 minutes or so) the house gets warm.

What SMART RESPONSE does is uses an algorithm to attempt to get the house to the Programmed Temp BEFORE the Programmed Time. The result is the Furnace will turn ON an hour or more BEFORE the time you set to raise the temperature until it hits 70 degrees EXACTLY at 7 AM.

Okay– it’s a nice, cute helpsy idea that I’m sure a Honeywell Programmer/Engineer is rightly proud of. Problem is, the Furnace is BURNING OIL when I don’t WANT IT TO.

I didn’t notice what the Thermostat was doing until late one night I was watching a movie real late– when I heard the Furnace go ON and STAY ON at 4:30 in the morning. And I was like: “WTF?” When I went to look at the Thermostat, it displayed: ‘In Recovery Mode’

That was the Smart Response circuit attempting to ease the night-time temp back up to 70 degrees in time for 7 AM. Except that meant the thing was BURNING MY OIL AT 4 IN THE MORNING!! If I hadn’t been awake, I would never have noticed this.

So disable “Smart Response”. That way the Furnace only comes on when YOU program it to.
