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

I like it. It’s easy to read and nothing fancy. My other one was set on Celsius but I’m finding that I like the Fahrenheit better. You can change it if you want to.

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 sure he set it correctly, so I'm glad I looked at the instructions. It has occurred to us that, with these new thermostats, we are having to adjust the temp less often. Seems like we were always getting up from whatever we were doing and adjusting the heat or air up or down. It was a way of life, so now that we don't have to do that, we realize the thermostat is regulating the temp and not just a mechanism to turn it on and off. Duh! I would recommend this thermostat if you want a very basic, adjust up or down, select heat or air, be able to read the screen in any type of light unit. No wi-fi or app or voice guide or remote access, just basic manual control.

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.

Good illumination, simple to operate and no problem with response to ac and heat. Great value. Simple installation

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