    • Good product at an unbeatable price
Works well as advertised. The installation was somewhat easy as long as you are a bit of a handyman and follow the wiring instructions...

    • Easy, simple, cheap, wonderful!!!
I just wana say how easy this thermostat is to install and program. I replaced a non programmable thermostat in my apartment with this one. I live in the Midwest and it’s get pretty cold.. so I bought this little guy so I can’t set it to turn on a few hours before I wake up to warm my apartment up.. and when I leave it will turn off.. so I don’t have to remember to lower the temp before I leave.. the unit came with 2 screws, the plastic wall anchor thing and 2 batteries and instructions.. I bough mine refurbished for $18 and there are no blemished or issues.. looks and works fine.. I had the same exact model and brand but the basic one.. so I took a pic of the wires and just used that to install the new one. Very straight forward and simple.. programming took me less than 5 minutes.. I mean how easy was that!!! You program the weekday and the weekend separately.. honestly I don’t see why anyone wouldn’t be happy with this product.. I don’t have any experience with wires or even hvac.. just kill the power to your furnace and you should be safe.. honestly I’m thinking the bad reviews are just people who are not so very smart.. ... show more

    • Excellent Thermostat
I own two of these thermostats. One was a new installation for a new furnace, and the other was a recent replacement for another programmable brand. I find this product to be a great value considering its functionality. It is programmable separately for heating and cooling systems, which is always a nice option (some brands/models are "one season at a time" so you have to constantly reprogram every season). The 1F78 can be programmed for four programs for each weekday, as well as for programs for weekends. This is your basic 5/2 programming. This model DOES NOT let you program for individual days, so if that is an option you want, skip the 1F78. For example, you can program for Mon-Fri, and Sat/Sun, but not Monday independently. I've had that feature on other thermostats and it is nice if you like to maybe let the heat stay on later on a Saturday night compared to Sunday, for example. However, for the price that was a small sacrafice to me, given the other features and ease of use. I do like the EMR (Energy Management Recovery) feature on this thermostat. It "calculates", based on current temperature and desired temp/time when it should come on. For example, it you want it to be 70 degrees at 7 AM, you don't need to guess how early to start the thermostat in order to call for heat and reach 70 by 7 AM. You just set it for 7 AM, and what it does is come on about 5 minutes earlier for each heating degree it is below your set temperature. For cooling, EMR will turn on you A/C 15 minutes early for each degree above your set point. You can disable the EMR feature if you prefer. What's in the box: The 1F78 thermostat Instruction manual Two mounting screws Two screw anchors Two AAA batteries (mine were Duracell, obviously this could change depending on manufacturer shipping). Set up is simple. TURN OFF ELECTRICTY to your HVAC, which should cut power to your old thermostat (except for any batteries in it). Remove your old thermostat, taking note of the wiring colors in use. Tape/tie off your wiring cable so it does not fall into the wall!! Run the wires through the back of the 1F78 and connect to the appropriate terminals. Display is basic LCD - gray on gray, backlit in amber when you press a key. The display is easy to read. Controls are simple to understand, and you are used to programmable thermostats, timers, etc. you may not even need the manual to program this product. The buttons are basic - Time, Program, Run, Hold, and Fan (On/Auto) and System (Cool/Off/Heat). I have one complaint about this product, and its not a huge deal and you should only need to deal with it once - the wiring terminals. The terminals themselves are screw-down, which is nice since you don't have to wrap the wire on a terminal. But there is very little room in between the terminals, so it can be a pain to work the wires into each terminal to tighten them down. Overall, this is a reliable thermostat. I've had no issues with my first, which is about four years old, and the newly installed one took about 20 minutes to install. I would purchase this product again. ... show more

    • Good and Easy Replacement for My Old White-Rodger Thermostat
If anyone ever have any question what to replace if your thermostat is reading the wrong temperature, you can just replace the thermostat. My old White-Rodger thermostat (that looks externally exactly like this one) has started reading 14 deg F while it's still 69 deg F and I can't adjust thermostat lower than 40 deg F. I know I had to replace it. I was just worried that the temperature sensor was somewhere else and changing the thermostat isn't going to do anything. Well, when I opened the box and put the battery in, I'm happy to see that it reads 70 deg F. I was relieved that the sensor is at the thermostat. So I went and swap the old one with this one. The old thermostat only have two wires going into it: White and Red. I do believe Red is power and White is the heater signal. I just need to take out the old wires and removed the two screws from the thermostat housing to get them out. I routed the wires from the middle opening and put them into the W and Left R. It take some fenagling to put it the wires in without pliers but it goes in just fine. Making sure no exposed wires touching any other contacts or wires. The contact screws are much smaller on this model than the old one. You might need a precision screwdriver for it. Other than that, the installation was very simple. The housing uses the same screw holes as the old one. So the installation was REALLY easy and eventless. I tested the thermostat and it turns on the heater. All is good and we shall see how it performs in the long run. ... show more

    • Cheap, reliable, does the job
I have several of these for a long time. They were previously sold as White Rogers, now sold as Emerson. The electronics have changed over the years, but the outside shape and the model number did not. The thermostat is easy to operate and program, and I like that the LCD shows two temperatures at once: the current room temperature and the temperature the thermostat is set to maintain. One glance, and you know everything you need to know. The LCD is not backlit: if you plan to check the settings in darkness, you need a flashlight. This thermostat has only two programs: one for all weekdays, and one for the entire weekend. This is called 5+2. If you need more granularity, such as 5+1+1 (separate programs for Sat/Sun), or seven days (separate program for each day of the week), you need something else. Programming such a thermostat would take longer though, so only go for it if you really need to. ... show more

Easy to install with just two wires. Within a matter of minutes installed! Easy to program with just a push of a few buttons. Looks just fine on the wall. Good quality for the price.
