This 5-day/2-day programmable thermostat touts a backlight, easy-to-use controls, and simple installation, but for the ultra-low price, users sacrifice compatibility with multi-stage systems.

Pros: Consumers who are fine forgoing extras appreciate the simplicity of the Honeywell RTH2300B1012 (starting at $23; available on Amazon). In reviews on Amazon, users say this thermostat is extremely easy to install and set up, with straightforward instructions. They say it keeps their homes at a consistent temperature without much fuss. Reviewers also contend that it's quite easy to program, with intuitive buttons and a "hold" option that allows them to easily override any programmed settings and instead use the thermostat manually. Users also appreciate the backlit display, which makes low-light viewing a squint-free affair.

Cons: The Honeywell RTH2300B1012 does not have an adjustable temperature swing, which can lead to more frequent cycling of heating and AC units, and its system compatibility is slightly more limited. Aside from these deficits, a handful of users report quality-control issues with this thermostat. Several warn that they received displays with visible black smudges inside, and some say the display went out after a short period of use. A few even report units that arrived defective. Customer service receives mixed reviews.

Where to buy

Features: Like many budget-friendly thermostats, the Honeywell RTH2300B1012 has 5-day/2-day programming functionality that allows one program for weekdays and another for weekends. Each day is made up of four temperature periods. Users can also temporarily or permanently override the schedule. Potential buyers should note that this thermostat is compatible with only single-stage central heating and cooling; heat pumps without auxiliary or backup heat; millivolt systems; hot water systems; and gas, oil, or electric furnaces. It cannot be used with any kind of multi-stage system or heat pump with backup. It requires two AAA batteries and is backed by a 1-year warranty.

Takeaway: Anyone who wants a basic programmable workhorse that still has helpful features such as a backlight should check out the Honeywell RTH2300B1012. Apparent quality-control problems and a lack of compatibility with multi-stage systems keep it from a higher ranking.
