Reviews
"note : Picture of base if from my old unit, just posted to show wires, Red Wire is power, Green wire is Fan, Yellow is A/C and white is Heater."
"Biggest loss with this step-down is the lack of an automatic transition between heating and air conditioning, but I knew that going in."
"The "smart thermostat" devices were out of the question, too many reliability and security issues, expensive, and honestly really pointless loading apps onto cell phones etc., to do what haa! The great thing is no matter what if I lose power due to an outage no settings are lost and it restarts plain and simple."
"If you have a complex system, the manual has a chart that lists different wire color combos but it's the type of info that I'm not rated to understand. If you know what a changeover valve is and the difference when it's energized in heating or in cooling, or what an auxiliary heat relay is vs what an emergency heat relay is, then you can use the data provided."
"Originally had a simple thermostat which stopped working and our oil company installed a fancy model which drove me crazy."
"Only now, the temperature number looks weird - there's a number there, but it looks like it's preceded by a + or -, and I can't really tell what the setting is, so I don't know what temperature the house is supposed to be."
"Backlight feature is really nice as it allows u to see the settings easily something many even more expensive units will not do."
"It took me about 2 hours to install but only because I did not realized that I had dropped a small brass jumper piece which belonged with the new thermostat."

"Love this thermostat."
"Easy to follow instructions, but more clarification on connecting up heat pump installations with Aux Heat strips (orange and white wires) would be GREAT!!"
"I installed this in my grandparents home because it is very simple and easy to understand."
"This is the main unit on my 4 zone Hydronic system."
"Nice and simple install and non programmable so life's good ."
"I installed this in my RV."
"Works as promised."
"Had an HVAC company service person out to inspect heater and check out the non-functioning thermostat. I purchased another Honeywell from Home Depot, also a non programmable, that was similar but much cheaper and not as highly rated."

Emerson 1E78-140 Non-Programmable Heat Only Thermostat for Single-Stage Systems
This non-programmable thermostat works with most single stage heat only systems.
Reviews
"I do think that it's misleading that the picture has a backlit screen."
"The Emerson 1E78-140 was simple to operate and kept my camper very comfortable when heat was needed."
"I used this to replace the simple mechanical one that came in my Lance camper."
"Works very well, I would have given 5 stars but I wished it were a little less sensitive... it has a 1 degree window so my heater toggles on and off more than I like."
"Spend a couple extra bucks and get something better."
"Had a little trouble installing, but a short telephone call to the support line gave me the information on set up that was not clear in the paperwork that came with it."
"Have a millivolt powered gas wall heater common in Southern California apartments. Perhaps valve is at some threshold of operation, where slight voltage drop caused by minor increase in resistance of t-stat is enough to prevent activation?"
"Basically for two wire, red and white and heat only, Take off the red jumper then connect red to RH and white to W. My only reason for 4 stars is one of mine didn't come with the screws and drywall mounts and the poor directions."

Nest Learning Thermostat, Easy Temperature Control for Every Room in Your House, Stainless Steel (Third Generation)
The Nest Learning Thermostat is here to help make your home work for you. After a couple of days of manual adjustments, the Nest Learning Thermostat can anticipate when you would want to turn the temperature up, to help keep you cozy in the morning, and set the temperature down as you head to bed. With four beautiful colors to choose from and an easy to read display, this thermostat will help make your home not only smart but energy efficient. It’s called Farsight, and it lights up to show you the temperature, weather or time. A STYLE FOR EVERY HOME: The Nest Learning Thermostat now comes in four fantastic colors; Copper, Stainless Steel, Black, and White. Your Nest Secure can use your smart light bulbs to help get your attention in the event of an emergency; your smart washer and dryer can take the data from Nest and run the next load of laundry when energy demand is low. Nest is focused on making simple, human, delightful things. Home/Away Assist: Nest automatically turns itself down when nobody’s home to help you save energy. Farsight: When the Nest Thermostat spots you across the room, it lights up beautifully to show you the time, temperature or weather.

"I began to purchase LED light bulbs as a start, new energy efficient appliances, and then September 2015 the Nest 3rd Generation was released which caught my attention. I asked my father in-law who had the Nest 2nd Generation for information and he had nothing negative to say about it so I was sold. Test your wires one more time prior to uninstalling to make sure no power is running (avoid being shocked or damaging anything). If you have children you can lock it so that a child touching it can not change or disrupt your temperature or any of your settings. Nest will remind you when you should change your air filters on your furnace because it can base it upon how many times it turns on and off. Significant drop in energy consumption can be seen on my gas bill after month 1."
"The nest was not calling for heat and temperature was dropping fast. I called the nest techs which were polite and helpful. They said my nest was wired for a heat pump which I do not have. The nest was properly wired, but when wiring was check via the wi if it said it was erroneously wired for a heat pump."
"** EDIT: I am happy to report that the Nest Thermostat now has a number of options for the Farsight feature, including to display the current room temperature, which I wanted, and to display the weather outside (downloaded from the internet), which is very cool indeed! To charge its batteries, the Nest needs a C (common) wire hooked up; otherwise it tries to charge itself whenever the heating or cooling system is running -- the only time current is passing through it. If I turn the heating system on and set the thermostat to something low, like 60 degrees, so the heat won't ever turn on, the Nest displays "60" rather than the actual temperature in the room. Why should I have to wall-mount a thermometer next to the Nest to replicate its thermometer, just because the Nest programmers won't offer the option to show the current temperature?"
