Honeywell TH9320WF5003 Thermostat Review – Pros & Cons

Honeywell has been making thermostats for what seems like forever, and they’ve clearly put their experience into the energy saving features that the Honeywell TH9320WF5003 Wi-Fi 9000 thermostat has to offer.

Some of the thermostat’s special features, like the customizable color display, should prove attractive to those who’ve found the most popular wireless thermostats a bit too difficult to incorporate into their home’s decor.

Likewise, international users might appreciate the trilingual display, which also supports both metric and customary temperature readouts.


  • Display is large and easy to read even from far away
  • Independent fan control
  • Email alerts let you know if the temperature in your home is too high or low right away
  • Learns HVAC system performance to make sure temperature is right on time
  • Separate home and business modes give you the choice of overriding temperature settings whenever necessary
  • Vacation mode dials down HVAC settings while you’re away and then restores comfortable settings once you return


  • Internal temperature keeping might not always be accurate in some use cases, which can lead to HVAC cycling issues that turn the AC or furnace on and off at unexpected times
  • Warranty doesn’t cover residential customers
  • Struggles to work with certain types of furnaces connected to heat pumps
  • Requires to have a C-wire

Ease of Use

Operating the thermostat directly is fairly easy, since there are large comfortable simulated buttons on the touchscreen that make it simple to increase or decrease the temperature at any given point in time. You don’t need to navigate menus for simple changes, but there are quite a few levels to get through if you want to change some advanced settings.

Consider the case of auto changeover, which is an advanced function that allows the thermostat to change between running a furnace and the AC unit. While the function is disabled by default, as the following video shows, enabling it only takes a few taps of the finger:

Honeywell’s Total Connect Comfort smartphone and tablet app is slightly more streamlined when compared to what you get on the thermostat’s screen. The designers just put everything into linear menus that are easy to tap on.

You can sync several Honeywell-branded smart thermostats to the app at once. If you do this, then you’ll find that all of your thermostats are listed on an at-a-glance page. You can use it to view a weather forecast to help you select the right temperatures when scheduling.

Compatibility is pretty good. The Total Connect Comfort software is fully compatible with Android as well as Apple devices. The Wi-Fi 9000 version of this thermostat can additionally sync with Amazon’s Alexa platform to give you the freedom that comes with having voice control.

Controlling Home Climate

Setting the schedule is easy from the front panel of the device. You simply have to tap on the onscreen button and then you’re presented with a short calendar.

Unlike many other models, you’re restricted to a seven-day programming outlook with no ability to make changes for alternating weeks. When it reaches the end of the seventh day, it picks up from the start of the first.

If you have a custom schedule set, then the last hour of the seventh day leads into the first hour of the first day. While many users won’t mind this, some might see this as a limitation especially if they’re used to thermostats that allow you to configure a whole month’s worth of temperatures.

The preset energy-saving schedules come already programmed to adhere to this limitation. All periods are either defined as falling between Monday and Friday or on the weekend. Many users with custom schedules will probably set a workweek and a weekend schedule, so this shouldn’t be a problem.

Since the mobile app uses the same method of setting the schedule with almost the same interface, it shouldn’t be hard to get used to switching between the two. When you first turn the thermostat on, it starts up in what Honeywell calls regular home mode, which should be familiar to most people who’ve used programmable thermostats before.

There’s also an extra business mode, which comes with some options that should appeal to you if you’re using the thermostat at work. For instance, if you switch the thermostat into business mode, then there are some preset holidays that will automatically dial back the HVAC system when the calendar reaches them.

You can also set your own custom events when in business mode, but it should be noted that the Honeywell TH9320WF5003 Wi-Fi 9000 thermostat doesn’t take the initiative to learn anything about your routine. If you don’t configure it to do something, then it won’t do it.

Energy Saving Features

Most of the energy saving options are related to basic functionality. Wise use of the scheduler can save a great deal of power since you can set the thermostat to have the right temperature for the weather conditions at any time. While this isn’t much different from how a regular programmable thermostat, the Wi-Fi features means you can do this remotely if the weather starts to change.

You’ll see an updated weather report if you sign up for a free Total Connect Comfort account, though, so you can be sure that the thermostat will gently prod you to make the right call when setting the temperature. In fact, if you disable the At Home option, then you basically have a very sophisticated programmable thermostat.

With this function on, the thermostat will allow itself to power down your HVAC system to a degree when it doesn’t sense that anyone’s at home. However, some users have reported that it can be rather sensitive and pets might set it off.

Otherwise, the feature pays attention to both your settings as well whether or not someone’s home to check whether or not to dial back the AC or furnace. Honeywell offers a free monthly home energy report for all connected thermostats.

This report won’t change anything automatically, but it will tell you how you’re doing energy usage wise against other similarly sized homes in your area to the best of Honeywell’s knowledge. You can also configure email alerts to get notified if the temperature at home is extreme.

Integration with Smart Home Ecosystems

Since this thermostat is Amazon Certified, it supports voice control through select Alexa devices. Honeywell promises at at least further limited native support for the following platforms through the Total Connect Comfort software: Google Home, Samsung SmartThings, Microsoft Cortana, Logitech Harmony, and IFTTT.

Automatic alerts can be relayed to other Wi-Fi enabled devices. The thermostat can warn other devices when the filter needs to be changed. If you use a RedLINK Internet Gateway system, then you can pair your thermostat with it for further integration with your smart devices.

Total Connect Comfort also has a regular browser interface, which is good if you’d like to work with your Honeywell account through a regular computer. You can even use it with Linux if you’d like.

Honeywell TH9320WF5003 vs RTH9580WF

Honeywell’s RTH9580WF was supposed to go up against the Nest learning thermostat according to some reports, so we were interested in what a Honeywell TH9320WF5003 vs RTH9580WF showdown would look like. Once you’ve updated either of these thermostats, though, they start to look pretty identical.

That’s because the Honeywell RTH9580WF is the version for retail consumers but is otherwise very similar. Both of them have the same customizable display and programming features. The fit and finish on them both is pretty close to. The biggest differences come from the small print.

Honeywell doesn’t sell the TH9320WF5003 through their manufacturer’s page, and the warranty only mentions professional HVAC contractors. If something were to go wrong with the Honeywell RTH9580WF, then you can enjoy a one-year warranty even if you installed it yourself. Honeywell many not honor the generous five-year warranty on the Honeywell TH9320WF5003 if you install it yourself.

Final Verdict

Should you plan to have a professional install your thermostat, then the Honeywell TH9320WF5003 Wi-Fi 9000 is probably ideal. However, seriously consider the Honeywell RTH9580WF if you plan to install it youself.

The warranty differences are enough to make the switch and Honeywell has long considered it the version best suited for retail consumers judging from the fact that they don’t include the Honeywell TH9320WF5003 on their retail site.

The configuration process of the two thermostats is nearly identical, so you won’t be loosing anything if you made the switch. You might also look into the T-series from Honeywell’s Lyric line, which come with all of these functions plus more.

Various models of the Nest Learning Thermostat may suit users better if they’re looking for an autonomous experience where the thermostat does the work.

Also take a look at the ecobee4 if you’re looking for something with more sophistication when it comes to sensing whether or not you’re home as it uses individual room sensorsto accomplish this task.

If on the other hand you’re sure of what you’re doing electrically or you’re working with an HVAC professional, then the Honeywell TH9320WF5003 thermostat might be a perfect fit for you especially if you can find it at a better price than the competition.

The 5 year warranty and small details like the customizable display colors and the user-friendly interface might be very attractive.
