Honeywell has several smart thermostats that can connect to your Wi-Fi network and two of them are the Honeywell Smart Thermostat RTH9580WF and the Honeywell Smart Thermostat TH9320WF5003.
First Up: Honeywell Wi-Fi Smart Thermostat RTH9580WF
Honeywell created the Wi-Fi Smart Thermostat RTH9580WF to compete with Nest Learning Thermostat. We think that it is a very competent smart thermostat that gives Nest a stiff competition with its range of features.
Features of the RTH9580WF
Some of the main features of the Honeywell Wi-Fi Smart Thermostat RTH9580WF include:
- Wi-Fi enabled and mobile app. The name says it all. You can connect your Honeywell Wi-Fi Smart Thermostat RTH9580WF to your Wi-Fi network and then control and manage everything from your smartphone, computer, or tablet. You can use the mobile app to turn off your HVAC system when you are away and to turn it on even before you get home for instant comfort.
- Simple setup. The Honeywell Wi-Fi Smart Thermostat RTH9580WF is very simple to set up and you wouldn’t need to program it. To install, you just have to remove your old thermostat, hook up your Honeywell thermostat, and you’re good to go.
- Touchscreen controls. If you do not have your smartphone with you, no problem! You can adjust the temperature of your home using the touchscreen interface. What’s more, the screen has a changeable background color to make sure that it does not clash with your home decor and paint colors.
- Learns your behavior. Over time, the Honeywell RTH9580WF will learn your cooling and heating cycles, allowing it to optimize itself and give you the right temperature every time. This will help make you more comfortable while also helping you save more money.
Advantages of the RTH9580WF
- Relatively Easy Setup: Honeywell promises that you can install the smart thermostat yourself, and that the setup is quite easy.
- Smart Learning: Another advantage is that it is a learning thermostat. This means that it familiarizes itself with your behavior so that it could tweak the temperature at the right times, assuring you utmost comfort.
- Smart Scheduling: You can also work with a seven-day schedule. Scheduling the Honeywell RTH9580WF is easy as it is very smart and flexible.
- Works with Amazon Alexa: Moreover, Honeywell RTH9580WF works with Amazon Echo, so you can use voice commands to control the thermostat. You don’t have to stand or reach for your smartphone or your remote control at all. How’s that for convenience?
- Smartphone Notifications: Further, you can get maintenance notifications on your smartphone. If the filter needs changing soon, you would surely know about it.
- Can Pay for Itself: However, what really makes the Honeywell Wi-Fi Smart Thermostat RTH9580WF a good buy is that it practically pays for itself and it usually takes only a year to do so. For instance, living in New York City, the average household could save around $286 per year with this smart thermostat. The manufacturer has an energy savings calculator on its website if you are curious to know how much you can save using the thermostat.
- Plenty of Integrations: Lastly, you also have a range of integrations that helps extend the features and what you could do with your Honeywell Wi-Fi Smart Thermostat RTH9580WF. The RTH9580WF works with Samsung SmartThings, Amazon Echo, Logitech, Yonomi
, IFTTT, Panasonic Smart Home, Zonoff, Wink, Stringify, and other connected devices.
Things that Could Be Improved About the RTH9580WF
- Needs C-Wire: The Honeywell Wi-Fi Smart Thermostat RTH9580WF needs a C-wire. This means that if your current thermostat does not have a C wire, you might need to buy additional devices to make it work. Honeywell also gives alternative wiring instructions for those without a C-wire, but that would mean the thermostat will be stealing power from the HVAC system, meaning it might turn your heating and cooling systems on and off just to draw power for itself. This might also cause annoying fluctuations in temperatures and give rise to strange noises and other problems.
- Acts Smarter than it Looks: Also, for a smart thermostat, Honeywell Wi-Fi Smart Thermostat RTH9580WF looks very much like traditional and older thermostats. This might be good for those who want their thermostats to look like older thermostats, but compare that to Nest and other modern-looking thermostats and you would see that the RTH9580WF fails.
- Instructions Could be Improved: While the installation might be billed as DIY because you can certainly do it yourself, beginners might have a difficult time following the instructions given by the manufacturer. Also, your current thermostat might make the installation a more complex process than expected. Plus, the lack of a C-wire also creates another problem because the alternative wiring suggested by Honeywell might not work for every system.
Final word on the Honeywell Wi-Fi Smart Thermostat RTH9580WF
The Honeywell Wi-Fi Smart Thermostat RTH9580WF is a very capable smart thermostat that learns your behavior in order to keep your home’s temperature at the right levels for you at all times. Accessing, controlling and managing everything is very simple and easy because of the mobile app.
And while it does come with an easy and flexible schedule, you can do away with scheduling and just let it learn your behavior and use its algorithms to set the right temperature for you and at the right time.
Also, cutting all the hype and noise, the Honeywell RTH9580WF works really well. It follows your set schedules and its algorithms are spot on in learning your behavior. And you can also override things manually if you want the room to be extra warm or a bit colder on certain days.
Long story short, the Honeywell Wi-Fi Smart Thermostat RTH9580WF is a worthy competitor for the Nest Learning Thermostat. But it does look more like the traditional thermostat while Nest has a modern look.
Honeywell Wi-Fi Touch Screen Programmable Thermostat TH9320WF5003
Honeywell Wi-Fi Touch Screen Programmable Thermostat TH9320WF5003 has the following features:
- Personalized display. You can choose your own colors on the screen to help your thermostat match your room paint. What’s more, you would appreciate its high-gloss frame, making it look very classy and elegant.
- Easy set up. Set your Thermostat TH9320WF5003 easily. You do not even have to rely on a manual as you can just follow the installation and set-up process that you see on your tablet or smartphone.

These include the temperature and humidity inside and outside the house, the current date and time, the cooling or heating status, the current temperature set, as well as information on whether the thermostat is following your set schedule or not.
- Works with just about any heating and cooling systems. The Honeywell Wi-Fi Touch Screen Programmable Thermostat TH9320WF5003 works with a wide range of cooling and heating systems, including heat pumps, electric, gas, and oil. It can also work with 3H/2C heat pump and 2H/2C conventional.

Comparing the TH9320WF5003 vs RTH9580WF
The features and functionality you see on the Honeywell RTH9580WF are present on the TH9320WF5003. That means the same personalized display, the same easy set up, and the same compatibility with a wide range of existing HVAC systems.
However, you should take note that the Honeywell TH9320WF5003 is not a retail product and is only available from professional contractors. It comes with a five-year warranty.
Meanwhile, the Honeywell RTH9580WF is a retail equivalent of the Honeywell TH9320WF5003. What does this mean? The Honeywell RTH9580WF is available at retail stores and has a one-year warranty. You can install the Honeywell RTH9580WF yourself and the one-year warranty will still be in effect.
On the other hand, you should only let professional HVAC contractors install the Honeywell TH9320WF5003. If you install it yourself and something goes wrong, Honeywell would not honor the five-year warranty.
PLEASE READ: With that in mind, be wary and cautious when you buy Honeywell products. The Honeywell TH9320WF5003 is not sold from the manufacturer’s website but you can find it on Amazon. (Check here for latest price). This should not be the case, though, as it should only be available from professional HVAC installers. Naturally, people who buy it from Amazon are shocked when Honeywell tells them that the warranty has been voided.
Before you buy
Both the Honeywell TH9320WF5003 and the Honeywell RTH9580WF are highly capable smart thermostats that have all the features you see in other similarly priced smart thermostats, such as Nest and Ecobee3.
However, if you are looking for a smart thermostat that looks sleek and more modern, you might want to consider Nest or Honeywell’s own Lyric thermostat.
Ecobee and Nest also give you data reports that help you gain insights on how you use energy and more importantly, guide you on how to save more.
The explanation of the C wire in the paragraph below is completely false and needs to be removed. The C terminal, which represents common, is needed to complete the 24v (low voltage) circuit. It’s identical to the Neutral wire on a residential 120v circuit. Four wires are necessary for a traditional AC & Heating system. 1) Red- to send 24v power to the thermostat; 2) Green- will energize the fan through a switch in the thermostat; 3) Yellow- will energize cooling through a switch in the thermostat; 4) White- will energize heating through a switch in the thermostat. Older, now obsolete, mercury thermostats don’t require power to operate the equipment and only required 4 wires. Digital thermostats require power to illuminate the liquid crystal display. Most digital thermostats receive batteries to power the display with an option to connect the C wire (if an extra wire is available) to power the thermostat with the indoor units transformer. Some thermostats don’t have a battery option and need to be powered by the transformer as is with the Honeywell RTH9580WF and TH9320WF5003. The statement that additional devices might need to be purchased is completely false. At worst, new low voltage wire with an additional conductor might need to be installed between the indoor unit and the thermostat, which in most cases is simple and affordable. The statement of the thermostat stealing power from the HVAC system and it might turn the heating and cooling systems on and off just to draw power for itself is ridiculous and absolutely WILL NOT cause annoying fluctuations in temperatures or give rise to strange noises and other problems by any stretch of the imagination. The transformer in the indoor unit has more than enough power to energize the thermostat.
Things that Could Be Improved About the RTH9580WF:
1. Needs C-Wire: The Honeywell Wi-Fi Smart Thermostat RTH9580WF needs a C-wire. This means that if your current thermostat does not have a C wire, you might need to buy additional devices to make it work. Honeywell also gives alternative wiring instructions for those without a C-wire, but that would mean the thermostat will be stealing power from the HVAC system, meaning it might turn your heating and cooling systems on and off just to draw power for itself. This might also cause annoying fluctuations in temperatures and give rise to strange noises and other problems.
Thank you for the comment. I will take a look at the information you provided and update the article accordingly.
Have a great day!
I really disliked my RTH9580WF. Every night at about 2:00 AM the screen turns WHITE as if someone turns on a 60 watt light in my hall way. We have to keep our bbedroom doors closed each night. This is no an option and cannot be turned off or dimmed. Next, it has a 12 month warranty and my touch screen went blank/black after 15 months. My prior thermostat lasted 25 years.
Thanks for your comment, Shane. I did hear from other RTH9580WF owners that the light might be a probe especially if you live in a smaller apartment. Regarding the warranty that’s definitely a huge drawback and as far as I know, the company is trying to extend it to 24 months.
