Emerson 1F78-151 5-2 Day Programmable Thermostat for Single-Stage Systems

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.

good clear instructions and easy to install, this is the way to go, i have now tested my rooms and it seems with this new thermostat and some duct rework all the rooms in the house are { +/- 1 degree difference} @ outside temp, of less than -5degrees celcius, and above 5degrees celcius. you can turn it down by the HOLD or program it if you go away,. its great Thank You.

Good product. Instructions complicated so not for the average person. But happy with it.

I have installed a dozen or two of these thermostats over the years and never had one fail.This is a basic function programmable t-stat, it has a weekday program and a weekend program, you manually select heat or cool.It doesn't have a touch screen with a bunch of menus, 50 buttons or a 100 page manual to read, it doesn't link up to your network, phone or NASA -- none of that nonsense.Very easy to use, programming takes just a few minutes and if you want to temporarily override the program it is easy to do and changing back simply requires pushing run.It doesn't cost much, is easy to use and will control your furnace or AC unit reliably for years to come.Highly recommended.
