Our Verdict
The basic Honeywell Home RTH2300B thermostat offers straightforward operation and basic scheduling, but lacks the advanced features found in more premium models. Its simplicity makes it easy to use, with intuitive temperature adjustments and mode changes facilitated by dedicated buttons and switches. However, the absence of smart features and a mobile app means that remote access is not available, and scheduling must be done manually via the thermostat menus.
Our Analysis and Test Results
The Honeywell Home RTH2300B 5-2 Day Programmable thermostat offers simplicity and ease of use for temperature control, with straightforward scheduling options that are easy to navigate, although they may be a bit time-consuming. Its intuitive interface, complemented by dedicated buttons, ensures easy adjustments, while the inclusion of filter change reminders adds convenience for maintenance. However, we don't recommend it to anyone who lives in a warm climate.

Ease of Use
Setting the temperature and changing modes were intuitive on this model, thanks to dedicated buttons and switches for each function. Although the up and down arrows for temperature settings make for slower adjustments than touchscreen sliders, they worked fine with zero learning curve. Mode changes couldn't be any easier thanks to the three-way switch for Heat, Off, and On. The same applies to the fan, which features a clearly labeled two-way toggle switch for Auto and On.

While this is a straightforward thermostat to operate, it lacks smart features and does not have a mobile app available. That means no remote access whatsoever.
Hold status is pretty straightforward on this unit. It holds the temperature until the next scheduled event or until you disengage the hold via the dedicated Hold button. The display is nearly impossible to read from more than a few feet away, but the information is laid out logically. Clarity is fine if you're within viewing distance. We did ding it for not letting us see the current temperature and the set temperature at the same time, though. To reveal the set temperature you have to press an arrow button. The accuracy of the temperature displayed on the screen versus the temperature recorded by a temperature sensing data logger placed beside the thermostat was within 0.211 degrees Fahrenheit on average, which was fairly consistent and very accurate.
This wasn't the most convenient install, nor was it rocket science, but you'll need to bring a tiny screwdriver and some AA batteries to complete it.

DIY Installation
Installation of the RTH2300B is less guided than that of other thermostats, especially those with apps or polished instructional videos. With this one, there are little more than some helpful pictures in the paper manual to get you started. There's no mention of what tools might be needed or any reminders to take photos of the wiring of the outgoing thermostat in case things get confusing, either. And there's no built-in level or packaged wall plate, like on some of the premium models we tested. However, once you get the batteries (not included) inserted and the wiring screwed in correctly using a flathead screwdriver, you're pretty much home free on this install.
Scheduling
With the Honeywell Home RTH2300B 5-2 Day Programmable, you're limited to a 5-2 day schedule, meaning you set the same schedule from Monday to Friday, with a separate one for the weekend. Up to four events are schedulable each day. Since there is no app connectivity, everything has to be done from the thermostat menus with the onboard buttons. Begin by ensuring the thermostat is set to the desired system mode (heat or cool). You can switch between modes during scheduling to program both simultaneously, which is nice.

Smart Capabilities
Normally, this is where we'd report on things like the quality of the thermostat's app, its schedule learning capabilities, and smart home ecosystem compatibility, but, as a much more basic thermostat, the RTH2300B doesn't provide any of that. It does, however, offer filter change reminders that you can set to Off, 30 days, 90 days, six months, or a year.
It's nice that the RTH2300B lights up when buttons are pressed for those late-night adjustments.

Energy Saving
In terms of energy efficiency features, sustainable practices, and carbon offset initiatives, there are no notable features for the RTH6580WF. This basic thermostat lacks eco modes, energy consumption reporting, and grid-optimized consumption. Furthermore, we didn't find any information on sustainable packaging or carbon offset efforts for this product.

Should You Buy the Honeywell Home RTH2300B 5-2 Day Programmable Thermostat?
The RTH6580WF is about as basic as thermostats get these days. It's one of the most affordable models we tested, we wouldn't say that it's a good deal for everyone. For a bit more, you can get thermostats with companion apps that make them easier to configure and allow remote access, as long as you install them in the range of your WiFi network.
What Other Thermostat Should You Consider?
If you like more basic thermostats but want to kick it up a notch, we recommend the Orbit Clear Comfort. It's more programmable than this one and a bit easier to use at a similar price point. If you want to step into the realm of smart thermostats, we highly recommend the Nest Thermostat. This unit features a range of premium options and integrates seamlessly into the Google smart ecosystem. It's also very simple to install.
