Top Notch Digital Thermostat
This is an excellent digital thermostat and one of the best around, according to our professional HVAC company. It works perfectly and is easy to use, as it is a basic thermostat without all the bells and whistles.We highly recommend this product and the Seller. 110% happy customer!!!

Package of item issue
While the item works and replaced ours when I opened the outside pkg the inside thermostat box looked like it had gone thru a wind storm. The box was smashed and opened on both ends. Thank goodness the product wasn't damaged and worked but wow it had been thru something for sure when packaged.

It's all you need. Covers the requirements
Love the Emerson 1F85U-42NP Non-Programmable Thermometer. It's modern, clean, beautiful & covers everything you really need. I was smart & got the NON-programmable one this time. Why hassle with anything else? Why invite possible intrusions into your life with "Smart" thermostats & the hassle of setting those up? I tried "Smart" thermostats before & promptly returned them. I like the fact that it's NOT constantly lit up like all the "energy vampires" built into everything electric you buy. It illuminates to a soft blue when YOU want it to by hitting any button or touching the "illuminate" button on top. It's only been up a few days; all seems well. Only at the very beginning did it seem like the temp was a bit off, but it settled down in accuracy. If something changes in the future, I'll let you all know.

Great thermostat
Easy hook-up. Blue backlight is cool looking. Keeps very accurate temperature. You will need a neutral from furnace for the backlight to stay on. Just use a blank wire in the harness and hook to common on furnace and on thermostat (white). This is for gas/oil units. Heat pumps already use the neutral.

Better than a NEST
The best! , Nest thermostat do not have a hold function... you figure no big deal well, when a newborn is napping and your at home not moving around Nest will think that your are gone and go in away mode. Anyways this is such a simple, easy to use thermostat.Thank You Emerson

Does the job
I use this for a wall heater but it does have connections for fan and air conditioning. There is a short delay when you first turn it on after it has been off but you get used to it. The thermostat is readable in most lighting conditions and the display does light up when you touch any button. So far it works fine

It works.
It's a thermostat. If it works it works. If bought the WIFI version I would give it a more through review.But it is what it is. It works just fine, has no problems and does what it's expected to do. That means 5 stars. U der performing gets less and outstanding in some way gets more.It's just another thermostat that does it's job.
