I nice update for our 20-year-old Honeywell thermostat.

I read many reviews on these and was hesitant about buying it because of the warranty issue (must be professionally installed, etc.).  But I liked the features it had, such as automatically switching between heat and A/C.  Where I live, the climate is dry and we have large temperature swings from day to night. Our previous thermostat was an electronic programmable Honeywell one, so learning how to program this one was not very difficult.  I think my wife would have struggled with it, however.  I had an A/C service guy come recently to check our system.  When he saw this he said a lot of people have trouble figuring out the programming.  I also like the 'circ' fan feature, rather than just 'on' and 'off'.  It helps keep the temperature upstairs closer to the downstairs temperature without running the fan continuously.  I had unused wires going to the old thermostat so I was able to power the new thermostat and have the panel lit all the time.  It is dimmed a bit until you touch the panel.  I also used the 'vacation hold' feature when we were traveling.  The white plastic trim looks kind of cheap and I wonder if it will yellow over time.  Otherwise I would give this 5 stars.

[[ASIN:B004AP92N2 Honeywell Econoswitch RPLS740B 7-Day Solar Time Table Programmable Switch for Lights and Motors]

I installed the switch yesterday.  It was fairly simple.  Of course turn your breaker off.  Keep in mind you need to connect a neutral wire that is usually in your box.  I had two light switches next to each other, the porch light and the hall light.  I got a new "rectangular" switch for the hall light that matched the look of the Honeywell switch.  I was surprised how easily it fit in the old metal box.  The most difficult part was cramming the spare wire back in the box.

Now for the fun part, the programming.  The flow chart was designed for someone with super great near sightedness.  It is confusing because the instructions keep sending you back and forth between two pages after you eliminate the pages in other languages.  I looked on line for easier instructions but had no luck.

I found it easiest to learn the commands and then follow the switch LED instead of the flow chart.  Once you "get it" it would be easy to do a second time but Honeywell needs to seriously look at hiring better technical writers. Looks good and I believe it is the most durable compared to other brands but be prepared to be patient on the programming.

One last note.  In the automatic mode it is suppose to adjust for daylight savings time but I am not certain it is set to adjust to the newest DST.  This may be why it was out of stock on the Home Depot website because they are updating the model.  There is a simple adjustment to add or reduce time so it's not a huge deal.

I purchased this thermostat after watching TWIT's Try Before You Buy podcast.  It was recommended, and as we weren't happy with our existing programmable thermostat, we decided to try this.  As reported, installation was great.  The kit comes with a handy screwdriver and wall plate.  I used both, and this install looks nicer than my previous did.  The wiring install was relatively straightforward with one glitch.  The kit did not have stickers with all of my wire labels (ie mine differed slightly from the labels) amid inadvertently labelled one wire wrong.  Also we had a jumper cable, and it wasn't immediately clear what to do about that.

Wiring went in easily.  I searched Nest's site on what to do about the jumper, and easily found the remedy (Nest says it detects that you need a jumper and takes care of that electronically).  Because I had mislabeled one wire, when we booted the thermostat, it said I had a heat pump and no a/c (wrong). Took a quick look at the digital pic I had of my old setup (protip - take a picture of your wiring before messing with it!) and realized my mistake.  Reinserted the wire in the correct slot and bingo, we were in business.

Connected to my wifi easily enough (do check the Nest's website, there are some routers that the Nest doesn't cooperate with and this can be a big issue).  Set my locality, the thermostat downloaded software updates and it was running fine.  It has taken a few days to get the full feature set - the nest has to learn your system to estimate heat up and cool down times.

I like the app - it provides quite a bit of consumption information, such as how long your furnace ran on a given day.  We have made use of the away function (setting the furnace to a minimum temp while away) and the scheduler.  The scheduler is excellent and very flexible.  Each day can have a different schedule, or you can let the auto scheduler handle things for you.

One note, the nest uses a rechargable battery that leaches from your main control line.  If your furnace/ac does not support that, you probably can't use the nest.

Overall, I love the interface.  It is simple and much more friendly than the replaced thermostat. I take one star away for price.

Simple, easy to install, works great.
Replaced the old thermostat that was programmable, and decided to run its own program, switching temperatures around..

This is a great thermostat.  It is user friendly and easy to read.  It like it so much better than the previous Honeywell thermostat I had.

Easy to use and better than my previous generation Honeywell programmable. Being able to hold a setting until a specific time ( or for a certain number of days for vacation hold ) is a big improvement since the previous unit would only hold until the next program kicked in ( i.e. wake, return, sleep etc. ). I also like being able to group a set of days for programming. The older unit restricts you to Mon-Fri as a group but this unit allows any grouping you need. Had my HVAC guy install it during the pre-summer checkup and it went it with no problems. Other thing I like is it runs on house current and the batteries are only there to hold the settings in case of power outages. I've had thermostats running on batteries only and the displays go dim when the batteries are low.

The thermostat is just as described. It replaced a low-end programmable Honeywell we replaced 5 years ago when we moved into our house that broke when it got shocked from static electricity and my finger (ouch!). This was half the cost of the one we bought from Lowe's 5 years ago, but has more features so we were worried it wouldn't be what we expected. We have been pleased with it feeling that it is definitely an upgrade to the model we had before and it was much less expensive.

A little harder to install than I was expecting, but that's really the fault of my wiring, the old thermostat didn't use a Common wire, once I got that fixed it was easy.  Pretty easy software setup too.  A couple of times when I tried to change it remotely it didn't save this changes, so I usually check it again after an hour or so to double-check.  Works great 95% of the time, still a vast improvement over a non-wifi thermostat.

This thing is nice!  Easy to install and much better than my original 1410.  And the timer option is a must.  The built-in thermostat seems a little off but I'd buy this one again for sur.

Easy to install and I don't have to do it for ten more years.

As promised in the company circular and with other reviewers, installation was simple! Purchased for compatibility with a two-wire, non-powered system (circulating hot water). Programming and operation straightforward.  Overshoot much improved over our 10-year old set-back thermostat, so now we have to adjust to not having those hotter moments in the house!

We have two heat pumps in our home and lost a smart thermostat on one of the systems with a lightning strike last week. I purchased this thermostat to replace the one that was damaged. It was reasonably easy to install and to perform the installation setup (you'll need to know a few technical details about your HVAC model to do this cleanly). It's a good product. The unit is supposed to come with three AAA batteries (I know because I had another of the exact same model that I recently installed) but the one that I received was missing them. The box was also written on with a marker. Still, all of the OEM screen-protecting plastic was still on and the product looked, installed and operated as new. Programming is easy, too. Unless you really want to, you don't have to pore over the manuals to get started with basic programming. The touch screen controls are easy to use and the screen is well-organized and logical.  I'm very happy with the performance of this themostat.

I have had it for five or six years. Zero complains. Last weekend I changed thermostats (veeeeery easy) and clean by myself heating elements (veeeeery easy too), 15 mins job. Working as new...8-)

We replaced an old (18 years) thermostat for our heat pump at a very reasonable price. We don't need one that is programmable and this works just fine. Easy to read and simple to understand the controls.

This product is a great alternative for our 107 year old home rather than trying to rewire.

Its great to see Z-Wave thermostats go mainstream and offer great features.  When I was considering upgrading my existing Z-Wave thermostat, I considered several other "new" thermostats, such as the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Nest-Learning-Thermostat-T100577/dp/B006ML9J4O/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Nest Learning Thermostat T100577</a>, but I had invested so much in my Z-Wave network I really wanted to stick to that type.

This Honeywell thermostat replaced an older Z-Wave Thermostat I bought several years ago, the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Wayne-Dalton-WDTC-20-HomeSettings-Controls-Thermostat/dp/B001F8QKYQ/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Wayne-Dalton WDTC-20 HomeSettings Controls Thermostat</a>.  Both units cost about the same money, but the amount of progress made in 3 years is astounding.

Like the Wayne-Dalton Thermostat, I chose to have this Honeywell one installed professionally.  Unlike the Wayne-Dalton one, which was almost impossible to install (you can read the reviews to see why), my heating/cooling folks put this on in about 15 minutes.

This what I love about the Honeywell:

- Touchscreen!  Nothing, of course, like an iPhone or iPad touch screen, but completely responsive and solid feeling.
- Large screen so easy to read (I chose to keep the backlight on continuously (no timing out)
- Filter reminder, with many options (days running, calendar days, etc).
- Adaptive intelligent recovery
- Ability to have fan run all the day, only when unit is cooling/heating, or at a set interval
- And of course, the Z-Wave function.  I'm using 5 year old software -&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Leviton-CCTEP-20W-ControlThink-ThinkEssentials-2-1-Professional-with-ThinkStick/dp/B001HT6Q24/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Leviton CCTEP-20W ControlThink ThinkEssentials 2.1 Professional with ThinkStick</a>&nbsp;- but I'm still able to set "normal" and "energy-saving" features for both heating and cooling.  The Honeywell is immediately responsive to Z wave commands (the Wayne-Dalton took a few minutes go think about it...)

The one negative is that there are many options, but none of them are available through intuitive menus on the screen.  Instead you have to put in specific codes provided by the instruction manual.  Clearly, the idea here is to have your installer do the programming for you, but as a gadget freak, I wanted to do all the programming.  Once you figure out how to do one, you can do them all. Just don't lose the instruction manual!

In sum, the Honeywell has everything I want, both in terms of a good Thermostat and in terms of a Z-Wave device.

I had more difficulty setting the time and temperature points than others seem to have had, but I think I've got it now.  Control of temperature is quite precise, holding to 1 consistently.  Instructions were understandable, no surprises.  I hoped that the mounting screw holes would be in the same place as the old thermostat, but they weren't and new holes had to be drilled and old holes patched up.

I am satisfied with the performance of this thermostat.
