  • Awesome Buy on Thermostat
Works great and half the price of Name brand... and the same Thermostat with different name on it..

  • Easy to use - Easy to Read - Looks Good - Long Lasting
This is a replacement for one I had. I prefer plain & simple, where I can turn the air conditioner, heater, or blower on and off when I want it and still have the thermostat tell me the temperature of the room, even when off. It looks good and is easy to use. If you don't want all the fancy settings to program and re-program, this is for you. My last Emerson thermostat was the original when the house was built in 1979. You can't beat that kind of durability! I am not familiar with wiring, so I had someone install it, so I cannot comment on that, but the wires do have to be hard-wired (not plug-in, like a computer). So I went down 1 star for install. But none seem to be for a lay-person who know nothing about electricity. ... show more

  • Great simple digital thermostat
The thermostat is nice, it was easy to install, however I thought it lit up when changing the temperature, but it does not, that was my main purpose for buying this model, but still work well and is accurate.

  • Good replacement for the old school one.
Perfect replacement for the old one if you don’t want to up grade yet. I used it for AC only.

  • Vertical Thermostat Model Is What You Get!
The vertical model of the thermostat, 1E78-144, is what you receive. While it would be okay for a new installation with limited horizontal space, it is not okay to replace an existing horizontal model.
