    I use a pellet stove and It sure is nice to get up in the morning to a warm house. It works great, Probably a alittle bit of an over kill for my aplication but the extra features are there if i need them in the future I just have mine set to go off at 11:30 pm and come on at 6:30am Since the day temp is changing now and each day is different, I either let it run all day or manually turn it off till I need it. Good Product

    The Honeywell RTH221B1021 is a basic 7 day programable thermostat, which was easy to install and operate. But as a retired person it would have been helpful had the instruction book included hints on how to program the thermostat for those who don't "leave home" to go to work each day, or 5 days a week. You basically have to program the thermostat to keep the same temperature at "waking" for the "leaving" setting and the "return" setting. So, in effect, the only times the temperature is automatically changed is "sleeping" and "awake". Other than this programming issue for those of us lucky enough to be retired.....great unit....great value.....great convenience!

    The installation instructions were very clear and complete. The setup instructions could have been better. This unit has the same program for every day, but the instructions say to select the day of the week which is confusing. You just have to skip this step. Otherwise, everything is OK.

    Customer has been confirmed to have purchased the item from Walmart.

    I didn't need different setting for different days of the week, in fact for cooling I really only need two setting (day and night) as I'm retired and around most days. For heating I'm a bit fussier as I like to sleep cool but get up in a warm house. This fits the bill and was easy to install replacing my old one (as soon as I reconciled the wires coming out of my wall with the colors in the installation guide and I easily got help with that by calling Honeywell support). There's a slightly longer delay than I was used to (especially when you first turn it on) when you change a setting manually but I got used to it.

    Instructions are a little difficult to follow but once it is set up it works well and saves big bucks. A deal for Wally's price.

    1) Turn-on temperature does not agree with setting temperature. It kicked in at about 4 degrees above the setting while expectation should be about 1 degree below the setting temperature. 2) Other thing: The unit is very difficult to open to install or replace batteries. It would be much better with a separate and easily open battery compartment similar to the one I have, Comfort-Stat CP1717. Honeywell should go to this direction for its more friendly-use products.

    The thermostat was easy to install and works great. It is hard to see the settings and I wish it had a backlight but for the money it is a big improvement over my old non programmable one.
