How Do the Models Compare?

Honeywell 9580 vs. Honeywell 9585

As we mentioned before, the Honeywell RTH9580WF is simply an older version of the RTH9585. Both models boast easy-to-follow step-by-step instructions. Keep in mind that you may need to acquire additional installation equipment if you do not have a C-wire.

While both the 9580 and 9585’s instructions are written clearly, we recommend using an instructional YouTube video to guide you through the process.

Both thermostats are also easy to set up. They are preprogrammed with an on-screen setup program. We recommend tossing the user manual aside and focusing on the prompts.

Since both models are compatible with the Total Connect Comfort app, you’ll also want to ensure that you have an up-to-date phone or tablet.

Design

Both the RTH9585WF and the RTH9580WF screens measure 4 1/2 inches diagonally. As such, they are both large enough to display key temperature and scheduling information.

The RTH9580WF boasts four easy-to-navigate menus. These include “HOME,” “FAN,” “SYSTEM,” and “MENU.” The RTH9585WF also has four headings, although the third and fourth headings consist of “MODE” and “SETTINGS.”

To give you an idea of how much information is displayed, both the RTH9585WF and the RTH9580WF’s “HOME” screens feature a large indoor temperature reading, an outdoor temperature reading, the system status, the temperature setting, and the schedule status.

Verdict

Since the RTH9585WF and the RTH9580WF are identical in size and both feature customizable interfaces, the winner of this roundup is the RTH9585WF by default.

Functionality

Both the RTH9585WF and the RTH9580WF connect to a C-wire. This is the source of power for your thermostat. What’s more, both systems work with common 24 VC heating and cooling systems, including forced air, hydronic heat pump, oil, gas, and electric.

Neither the RTH9585WF nor the RTH9580WF can be used with millivolt systems or 120-240 volt systems, such as gas fireplaces and electric baseboard heat.

While many conventional thermostats require a C-wire, they are not always used in older thermostats. It’s important to note that both models much also be connected to a C-wire to establish a Wi-Fi connection.

Verdict

Both the RTH9585WF and the RTH9580WF require 24 VAC power. This is a common requirement for conventional thermostats. Since there is no difference in power between the two models, the RTH9585WF is once again the winner by default.

Overall Verdict

While it was difficult to delineate between the RTH9585WF and the RTH9580WF, we recommend purchasing the RTH9585WF. As Honeywell’s more recent release, we think it’s safe to say that this thermostat is here to stay.

Honeywell 9580 vs. Honeywell 9320

Honeywell’s Wi-Fi 9000 with Voice Control (a.k.a. the 9320) offers a unique advantage over the 9580. Users can use their voice to activate and control the temperature and settings on this thermostat.

However, like the 9580 the 9320 is also compatible with Honeywell’s app and can be controlled remotely via smartphone. Both thermostats also boast customizable smart screens.

Of course, the 9320 is a bit more complicated in terms of installation. While it can be purchased on third-party sites, Honeywell does not sell it directly to consumers.

Instead, they recommend purchasing it from a qualified home contractor who will professionally install the device at an additional cost. Keep in mind that the thermostat’s 5-year warranty is not activated unless it has been professionally installed.

How to Use Voice Control Commands – Honeywell Wi-Fi Smart Thermostat with Voice Control:

Design

The 9320 is 3 1/2 inches high, 4 1/2 inches wide, and 7/8 inch deep. It features a black frame. This design is identical to that of the 9850. Both models feature super busy interfaces with four nested menus and customizable backgrounds and fonts.

Verdict

Since the 9320 and 9580 are virtually the same in terms of design, it was difficult to distinguish a clear winner. With that being said, the 9320 has built-in voice control, whereas the 9580 requires Amazon Alexa for voice control.

Considering this, we’d say the 9320 has the potential to take up less space while providing the same features as the 9580.

Functionality

Both the 9580 and 9320 require 24 VAC power that is accessed via C-wires. With that being said, Honeywell recommends that a contractor install the 9320, while the 9580 is suitable for D.I.Y. installation.

Beyond that, the two thermostats offer identical interfaces, setups, and programming options. Both models also provide smart alerts, including air filter replacement reminders, humidifier pad replacement reminders, and high/low-temperature alerts.

Finally, both thermostats are Energy Star certified.

Verdict

If you’ve successfully pinpointed a C-wire and you’re comfortable installing a thermostat, the 9580 is the way to go. This thermostat is an easy and straightforward replacement for any preexisting home thermostat. It will save you money and hassle from the start.

The only downfall is that you’ll have a shorter warranty than you would with the 9320.

Overall Verdict

With that said, the winner of this roundup is the 9580. While we enjoyed the 9320’s voice activation and extended warranty, we didn’t feel these features were worth paying a professional contractor.

Honeyewll 9585 vs. Honeywell 9320

In our last roundup, we took a hard look at the Honeywell 9585 vs. the 9320. As we’ve already explained, these models are barely distinguishable from one another.

The main differences are the 9320’s built-in voice activation and control settings, extended warranty, and professional installation requirement.

Design

Once again, the 9585 and 9320 have virtually identical screens and interfaces. The only difference here is the 9320’s voice activation element.

Verdict

With that being said, the 9320 is the clear winner in terms of design. This is mainly because it boasts more advanced integrated features, such as the onboard voice activation system.

This feature gives users more autonomous control over their heating and cool systems. As such, this thermostat fairs well against the competition.

Functionality

Both the 9585 and 9320 require a 24 VAC C-wire power connection to power up and connect to Wi-Fi. Both models also have the potential to inaccurately register inside temperatures, a flaw which can lead to some pesky cycling issues.

Verdict

The 9585 and 9320 are virtually identical in terms of power and performance. The main difference here is who’s connecting the wires. Since the 9320 requires a licensed HVAC contractor, our go-to choice is the 9585.

Overall Verdict

The main difference between the 9585 and 9320 is availability. After all, Honeywell doesn’t sell the 9320 directly to retail consumers. Instead, it must be purchased through a professional HVAC contractor or from a third-party retailer.

What’s more, the 9585 boasts a 1-year warranty, while the 9320 comes with a 5-year warranty. Given the facts, we feel that the 9585 is better suited for moderately handy homeowners who are looking for a budget-friendly update to their residential HVAC system.

F.A.Q.

Will the Honeywell smart thermostats work without Wi-Fi?

Yes. The thermostats will continue to regulate your home heating and/or cooling system without Wi-Fi. However, you will not be able to tap into the Honeywell Total Connect comfort app. What’s more, the 9320’s voice control feature will not work.

Can I install a Honeywell without a C-wire?

No. All of the models require a C-wire for attaining 24-volt power. With that said, you may be able to circumvent the C-wire by using an extra wire to connect to the C-input on the thermostat or by installing a Honeywell Wire Saver Module (THP9045A).

Lastly, you can hire an HVAC professional to install new wire.

What does the manufacturer mean by “customizable color screen?”

All three models boast full-color touchscreens with customizable color themes. Users can select from colors and predefined backgrounds or create a custom background using hand-selected color and text combinations. Users and also adjust the screen’s backlight settings.

Do the Honeywell thermostats have adjustable language options?

Users can choose between English, French, and Spanish languages.

Can I use more than one thermostat in my home?

Yes. The Honeywell smart thermostats can be paired together to create a whole home heating and cooling solution. Users can create a custom name for each thermostat. These names are used to delineate between thermostats on the Honeywell app.

What if my Wi-Fi router doesn’t have a strong enough signal?

We recommend using a device called a repeater. Wi-Fi repeaters amplify and rebroadcast wireless signals to create a stronger secondary Wi-Fi network.

Do Honeywell smart thermostats stand a chance against the competition?

The Honeywell smart thermostats are intuitive and easy to use. However, we are seeing many newer, sleeker thermostat designs popping up in the market. Still, the familiar digital interface and nested menus may appeal to traditionalists.

The Bottom Line

If you’re planning on hiring a professional to install your new thermostat, the Honeywell 9320 is a solid choice. Yet, we recommend the Honeywell 9585 to anyone with basic wiring knowledge and a preexisting C-wire.

While the 9320’s extended warranty is appealing, it doesn’t outweigh the cost of hiring an HVAC professional.

While we haven’t forgotten the Honeywell 9580, this thermostat is simply a more outdated version of the 9585. As such, we so no need to choose it over the 9585 nor the 9320.

Of course, all three of the Honeywell thermostats have nearly identical interfaces and features. With that said, there is no wrong choice in this roundup. Overall, the Honeywell smart thermostats are great options for most home heating and cool systems.
