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!!!!

Great Replacement
I got this to replace an old round mercury-switch version that looked identical on the outside except for color and material. I initially thought that I would just be able to pop this on, but the instructions looked daunting. I read through the instructions 4 times over a week or two before finally deciding that I needed heat on a regular basis. Although some of the instructions could have been clearer I got through it in just about 15-20 minutes. Not all labels on the original thermostat were clear as to which post/wire they were representing, and the blue wire was sitting unattached directly between two posts so I initially mislabeled it... turns out it was supposed to be the unused "B" wire. The new base/wall plate that was to replace the old one attached to the wall was missing the big hole that the wires run through coming out of the wall (but did match the old base plate perfectly otherwise). So that I wouldn't have to move the thermostat over 6" or so on the wall to fit the new base plate (drilling plaster was the last thing I wanted to do), I just left the old base plate and connected the new assembly to it. I've got a two-tone thermostat now, but it doesn't look all that bad, and more importantly... I have heat! I did forget to set the Cycle Rate switch, but turns out that the factory setting is correct for my system. The two control switches (heat/cool, on/auto) have a different mechanism inside than the old thermostat, so the solid "click" is gone, replaced by a softer, mushy, less diffinative muffled click. Comparing the setting on the thermostat to the built-in thermometer, the temp is only about a half degree off. I am keeping the setting lower now... maybe I'm more used to the cold now. UPDATE: A few months down the road and the temps outside called for the blower to bring the cool air up from the basement, and eventually a need for A/C. Neither worked, and my heart sank. Turns out that the unused "B" wire - in my case anyway - was what was needed for both the blower alone and the A/C with blower (the cool side). Since I still had the original thermostat I carefully looked at how the switches on the cool side worked then pulled the new thermostat apart (after turning off the power at the breakers), and hooked up the "B" wire. Now it's done.

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.

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.

For the not so tech savvy...
After the 3rd time my elderly parents (80 somethings) called me to come and "fix" their programmable thermostat, this easy to read, easy to use Honeywell was installed.Old people seem to not be able to regulate their body temperature too well so they are always fiddling with the thermostat.With the old one they would accidentally program the HVAC with sometimes horrific results.They can adjust this one to their hearts content without all the frustration they experienced from the "fancy" model.I don't know how accurate it is, but I do know it keeps my parents happy. We were lucky to find one here on Amazon....they are zero models like this in our little town
