Customers say
Customers find the thermostat works well, is easy to install and operate, and appreciate its retro look and simple, non-programmable design. Moreover, it doesn’t require batteries, and one customer mentions it works well with older furnaces. However, temperature accuracy and reliability receive mixed reviews – while some say it stays at the set temperature, others report inaccurate readings, and while some find it well-made, others consider it low quality. Additionally, the size receives mixed feedback, with some saying it fits perfectly while others find the numbers too small.

THE BEST!!
Dome style thermostat for heat/AC & WORKS without all that crazy programming!! (I could never figure out all of those settings and I replaced that dumb digital one!) I love the Honeywell dial! So easy and it works GREAT!!!!

Easy to use.
I don’t care for digital thermostats. Was happy to find this one to replace my old one.

Welcome back analog, good by digital.
The digital thermostat that was installed by our utility at no cost several years ago, was never really of high quality. The vinyl covered flat push button screen was something out of the mid 80’s it seemed.It was never very responsive, you had to really push hard on it to make any adjustments, and eventually,actually rather soon after installation, the vinyl started cracking under the pressure of where the push buttons were. Several of the buttons just stopped working all together. Luckily not the most important ones.It was always a few degrees off. And the utility had the ability to cycle it when they deemed necessary on peak usage. That always has kind of bothered me. I’ve known the thermostat was needing an upgrade, and obviously so did the utility.They offered a new Google thermostat for only $60.00. A pretty good price, but here’s the catch, I had to sign a waiver to give the utility even more control over my usage.So I thought, man I miss that analog device, do they even still sell them. And boom, I found this Honeywell thermostat, and ordered it. It works great, and is accurate, and we have full control, at least at the thermostat level, of how we want it set.My wife likes it even more. She loves the simplicity of the old style, just point the needle where you want it, and it’s done.

Perfect for what it does.
It’s the round thermostat that you know and love. Perfect for my tech challenged in laws who just want an easy to use device without programming and timers.

Great basic thermostat – owner’s/installation manual virtually useless.
Replaced an old/original Honeywell ‘Round’ with this 2 years ago. Recently it started to act erratically, cycling on and off at frequent intervals much shorter than normal. There are no instructions on how to disassemble and – even though I noticed when installing it – nothing about replacing the battery. It takes a #2450 ‘button’ battery and it turns out the erratic behavior was probably the result of the ‘anticipator’ not getting proper voltage. Replacing the battery was not a simple, straight-forward process so if you are uncomfortable opening up things, do a search and you will find several videos for guidance. The original ‘Round’ didn’t require a battery since it drew the small amount of current needed from the HVAC unit. With a new battery – everything’s working fine now.

Honeywell Home CT87N1001/E1 poorly redesigned former workhorse
Skip to the bottom to read about the problemThis redesign was completely unnecessary and is so inherently flawed that, in the old days, In an American factory, the first inspection of the first unit would have been dismissed as defective and several heads would have rolled for letting it get that far. And in a union shop, union guys would have been enraged and probably refused to make them in the first place which is why many American companies are PROUD to pay their people the big bucks. That’s how bad these are. It’s not merely a “flawed” design. It’s an inherently *defective* design.Purchased used, from Amazon Warehouse. I noticed, right out of the plastic bag, that the top cover wasn’t seated properly. The reason is a defective redesign of what was once the most reliable piece of equipment. Whether the damage was caused by someone trying to install it or in the factory on assembly, I have no idea.I’m going to fix and “frankenstein” mine because I’m a tinkerer but, as it was designed, there’s a pretty good chance installation will bugger up the *required* electronic connection when putting the cover on so, if you just like the looks and have to have it and want to use it anyway, get 3 but don’t get a “3 pack” because if there’s only one good one, they may not let you send the defective ones back. Chances are, a 3 pack will contain at least one survivor but if you only need one – what then? To refund, you’d have to send back the “3 pack” you purchased. It’s actually a very clever – though corrupt – way to get rid of a whole bunch of stock of an extremely bad design.One must also consider that if one ever has to remove the cover after installation, you have that whole problem of getting it back on without rendering it useless.The problem: Taking the cover off opens a cheap and delicate 6 pin electronic connector that must then be reconnected – blindly – when one replaces the cover and if it doesn’t go on perfectly straight the first time, seating the cover will bend whatever pins get caught outside their holes. It also appears that in trying to force the cover to seat properly and catch the latch, the plastic of the female side of the connector on mine was damaged and a small piece of that plastic is lodged down inside it blocking the hole of the pin I straightened. And it is an electronic connection so we’re talking about very tiny pins and very tiny holes. If you opened 10 brand new pieces, I’d bet that at least 3 of them will have bent pins and if you reassembled them and opened them again, I’d bet the number of bent pins would double.Buy at your own risk. If you’re like me and don’t read all of the bad reviews until you discover what you were sent doesn’t work, you’ll be left with the dilemma of either eating the money you spent or sending it back with the very real possibility that it will simply be shipped to someone else, compounding the problem of landfills that are quickly filling up with cheap, defective products.

Easy to switch out with the directions.

Good precision and easy installThanks !
Lynne Jeffries –
It’s perfect. Being retired, we don’t need one of the ones you can program………..if you even can. We had a programmable one when we were working, but, just wanted a good old plain one.

I got this for my rental as the local hardware stores did not carry any. Of course after a couple of months, my local stores had them for about 25% cheaper. Its a basic thermostat controller, on/off, should not be so pricey.

Simple design and accurate readings.Easy operation, no batteries to worry about. Could not be happier going back to non programmable and non wireless device.
