Non-Programmable Emerson 1F83C-11NP Conventional 1H/1C Thermostat

Leo R Graywacz: It was easy to install mainly because I was removing a thermostat and using this Emerson to replace it. So all the wires had been run and the system setup. It was very nice that the holes for the Emerson lined up with my previous thermostat so all I needed to do was to attach all the wires and screw it onto the wall. This thermostat had a place for my "C" wire which was tucked away because the old thermostat didn't have a connection for it.

I set up the thermostat before I installed it right after I installed the battery. I had planned on having the display backlight on continuously so I activated that function in the setup. The thermostat will come on 1º below the set temperature and go off 1º above the set temperature. It's likely 0.75º because that's what I have the differential set in the tech programming area.

I have multiple temperature sensors in the room. Of course they all read a little different. They read tenths of a degree. I ended up adjusting the thermostat 2º above what the original reading said to match my other temperature displays. It's more like 1.5º but it will only let me do whole degree number...

Denis Julien: un peu difficile a programmé , mais fonctionne très bien

Grant R.: Tried other brands, nothing was a good replacment for a system without a power wire, this one can do with or without a "c" power wire (thiis has "AA" batteries). I also added a backplate to cover up the old surface (from Emerson) . I highly recommend Emerson, very well made. It can be calibrated as well, and even has a built in level to make sure you install in correctly. Great company.

Maria: We did not install this ourselves but had our AC technician install it. I watched him install it. It's a wired unit. He installed it in less than 5 minutes and was a replacement for our prior thermostat. He said it was extremely easy to install. We've had it set up now for about a year with no issues. It reads the temperature extremely well as far as we can tell. It has a button on the top that you can push if you would like to light it up if it's not in a well-lit area. It is not anything fancy, and has manual buttons, but we prefer that. Keeping things simple I think keeps things more maintenance free and gives you more of exactly what you need - at least it does for us :) It looks sharp. We recommend this to others.

DV Phil: This product works great. it has some built-in features that makes it easier for the electrician. But it doesn't have a "Filter Change" feature as advertised.

Brad: The old unit had temperature increments of .5 the new replacement does not.

AUS-USER: Thermostat is simple to use and on/off temperature points are consistently precise. It has been connected to a gas heater. There has been no instances of relay chatter while cycling. Deg C has been used and slow cycling gave a temperature variance of approximately 1.4 deg C while medium cycling variation was around 0.8deg C. A "C" wire has been connected and the backlight remains on at all times. The backlight is not blue as shown, but a white/grey colour. The room temperature display is easy to read at night with no other room lighting. During the heating cycle the display shows "heat on" when the thermostat relay switches to call for heat. However, the "heat on" display lettering is relatively small and not easy to see. Its physical size is noticeably large. In summary, its simple, stable and functional with room temp easy to read. Delivered by Amazon (US) to Australia and arrived only one day late.

Rena Morra: Easy to install, but needed a jumper wire to accommodate heat pump.

G CraigG Craig: easy to install instructions were easy to understand , All I had to change was the switch from gas to electric system.
I like that the display is large and easy to read , nice large buttons , easy to adjust temps . seems accurate , heat shuts off just 1 deg above set temp, and never drops below set temp, ac temps are dead on,
What I really like is the battery meter as You can see in the pick . no more guessing battery state good back lighting .
wiring was a snap and this one does have the blue common wire
To date I have been thru 3 thermostats, one a white rodgers that was getting just old and the buttons were wore out, went thru a couple of honey wells that worked for a year then just failed .

I highly recomend this if you want a basic thermostat for a 1 heat and 1 cool system
a LUX tstat that just had too much temp swing.

AMS: We just had 2 installed in our home, one for a gas HVAC unit and one for an electric HVAC unit. We replaced two existing thermostats, one old and one new, because they were so darned hard to read! Too dark, especially at night. Had to keep flashlights handy just to read the screens, which were both way too small. These Emersons have large screens that light up briefly when you adjust the temp, but you can also light them up (briefly) via a button at the very top of the unit. You can also keep them lit if you have a certain wire configuration, which I'm not sure we have, but it is an option on the installer menu (need to read the user guide to learn how to access that menu; it's pretty simple). I don't think we would want them lit all the time since the screens are so big and the backlight is so bright. We had a plumber who was onsite to change a faucet install both thermostats. I watched him do it and am glad I didn't try it myself. It took him less than 15 minutes to do each one. I did point out to him, as I was reading the user guide to myself while he installed, that there was a separate setting for gas or electric. Since we had one of each, he made...
