1F83C-11PR Conventional (1H/1C) Programmable Thermostat

This review is for Emerson 1F83C-11PR Conventional (1H/1C) Programmable Thermostat, White. This is for a system with a 1-stage fan for the furnace. If you have 2-stage furnace, you will need a different model. I purchased this to replace an old White-Rodgers that I have had forever. It was still working fine, but I didn't like the small, non-backlit displace, and lack of features. I had tried a 2nd generation Google Nest Thermostat (which was causing damage to my system, because it did not function properly without a C-wire) and a couple of different higher-end, programmable (not smart), Honeywell thermostats. One of the Honeywell thermostats I didn't like the interface on, and the other died after a year. I wound up plugging back in my old White-Rodgers. Emerson and White-Rodgers merged, so I settled on this Emerson thermostat. I've been using this Emerson thermostat for a month. So far, it is the best thermostat I have used. The interface is excellent. Extremely straight forward and easy to use. The backlight and display are both excellent. I am running it off of 2 x AAA batteries. If I had a C-wire connected, I could run it off of that or that with the batteries as backup. If you connect the C-wire you can set the backlight display to always on. Speaking of setup, the initial setup was the best I have seen. The included manual was well written, and they have an excellent online walkthrough video. You can set filter replacement remind, adjust the readout temperature to more accurately represent your room, turn on/off the program feature, adjust the system for heat pump use, you can turn on an air conditioner power on delay protection feature to protect your compressor, and other features are available as well. I just touched on the main ones. If you want an easy to use thermostat, with good setup features, and excellent interface, this one is my top choice. Now, I'm hoping that I get many years of usage out of it. On a side note, a wall plate is no include. It can be purchased separately. If you have holes to cover or like the look, it is pretty inexpensive to get. I have holes from a previous thermostat that are visible, so if I may get the wall plate, unless I decide to patch & paint the area.

This replaced a two wire manual thermostat for my gas ducted heater in Australia. Installation was very easy and programming is relatively straightforward. Since this shipped from America, the initial setup was in degrees Fahrenheit, however it was very easy to change to Celsius in the settings. This is a great choice if a dedicated power source is not available.

This was a breeze to install and program. We installed one in our camper to replace the factory one and it works like a charm. Put one in our new house also. Simple and does what a thermostat needs to do.

If you're not getting a smart thermostat, this one has lots of features for the money. I have a large house with two boilers so I have two of these that I self installed. You can program it various ways for different times of the day. I like the fact that you can adjust the swing setting, (How much temp. fluctuation before the unit turns on), Emerson calls it the cycle rate with 3 settings and the middle one works fine for me. It's not a touch screen but the buttons are large and well marked. I do wish the screen was a bit larger but it does backlight when you push any of the buttons and if you have a C wire, (usually it's the blue wire), you can set the backlight to be on constantly. Most importantly this thermostat holds the temperature when and where you need it to.

Easy installation, compatible with Carrier HVAC. Simple, basic controls. Was for my mother's condo.
