Average thermostat
This is an average 7 day thermostat. It is selectable from cooling or heating. It has a wake, day, evening, sleep time range that are adjustable to your preference. This thermostat does not have a backlight display making it hard to read in low light.

Nearly unreadable in hallway with modest lighting
Model I bought was RTH221B and had a gray screen not green as shown. Thermostat display was barely readable making it unsuitable for intended hallway location. The contrast in the actual display was not at all close to that shown on product box. Installation was straightforward with markings on unit and good directions in installation guide.

    Straight forward install. Switched wires from the old non-programmable to this one and mounted to the wall and all went as expected.

    Once it is setup, it works very well!
    It was a little difficult to assemble at first because the schematic and directions were different than what I have at my house, but after toying with it with a friend we were able to successfully get it connected and working. It works really well and I love the fact that I can set up different temperatures at different times, so I can keep my energy costs low.
