Did you know that a huge chunk of your electric bill comes from your heating and cooling system?

With the ever-increasing rate of our modern-day expenses, having a programmable thermostat will be a huge help in pulling that expense down.

In this Trane XL824 Thermostat review, we’ll share with you exactly how you can achieve that.

Trane XL824 Thermostat Review

Trane is definitely one of the biggest names in the industry of HVAC systems.

In fact, they have been creating home comfort systems for more than 120 years.

They are known for their innovative design and excellent features.

This has even earned them the quietest sound rating among all of their competitors, particularly their Hemi Anechoic acoustic sound chamber technology.

The XL824 Thermostat is part of the Nexia Smart Home control system.

This allows you to link and control Trane home devices included in the series with a single app.

The series is a lineup of four different units, and the product that we are going to feature today is the second one.

The only thing lacking in this product, which is included in the other two units ahead of it in the series, is the ComfortLink.

This feature allows the optimization of humidity and temperature with advanced controls.

We believe that the XL824 provides the best balance between features and value for money, which is why we have chosen this unit to feature over them.

Who Is This Product For?

The Trane XL824 is excellent for homeowners looking for a high-end yet more affordable programmable thermostat system.

It can be remotely controlled through an app due to Wi-Fi connectivity.

In this way, you will be able to enjoy additional savings from your monthly bill without investing too much in a single unit.

As for the installation process, this unit is compatible with any conventional and dual-fuel heating and cooling systems.

It’s very specific when it comes to its wiring, though.

It is not compatible with any type of wiring (including C wires).

It will only work with Trane’s and the American Standard's three-wire system.

This is the reason why Trane suggests their buyers work with a Trane Comfort Specialist to get more information and insight into the use, features, and specs of their products.

What’s Included? 

If you do decide to purchase this unit, you can expect to get the thermostat unit, its mount (in the form of a back cover that you can simply snap off), the needed screws and adapters, and a comprehensive user manual.

Overview of the Features

What we absolutely love about this unit is the fact that it’s not just a programmable thermostat, it’s also an all-around temperature system that displays live weather forecast.

While most thermostat screens are boring and hard to navigate through, this one is equipped with a wide and colored touchscreen display that allows you to easily access all of its features.

You can even forget about standing up because you can control everything through your phone, from the comforts of your couch.

Another thing that we love about this product is its smart features.

It can automatically switch between cooling and heating, providing both comfort and convenience.

One feature that sets this product apart from others, however, is its diagnostic system.

You see, one of the main culprits behind a spike in your electric bill is an undetected issue.

This forces your system to push harder to compensate for it.

This unit is equipped with real-time diagnostic features that can alert you and (with your permission), Trane, if there’s something wrong with it for fast repairs.

As for compatibility, the Nexia app can easily be downloaded through any app store, but aside from that, this unit also works well with Amazon Alexa and Google Home.

Finally, Trane offers a 10-year warranty along with the product.

How to Program Your Thermostat Schedule in a Trane XL824

Let’s start putting the unit into action and schedule our preferred temperature for every day of the week through this simple process.

Step 1: Access the Schedule screen.

You can do this by tapping on Menu from the Home screen and then tapping on Schedule, which is the icon that’s second from the upper left.

Step 2: Set the grouping of your weekdays.

On the Schedule screen, tap on Grouping.

It will allow you to set which days are going to be grouped together, sharing the same schedule.

Once you’ve determined your preferred grouping, tap on Apply.

This will then take you back to the Schedule screen.

Step 3: Set your preferred temperature and periods.

There are generally three periods: Wake, Away, and Home.

  • Wake refers to the time you wake up.
  • Away refers to the time you plan to leave home.
  • Home refers to the time you expect to get home.

To add a period, tap on Add Period.

Then, tap on the temperature or the hours to set them accordingly. You can also watch the helpful video.

Step 4: Done.

Don’t forget to tap on Apply and save your settings.

You can now choose whether to follow your schedule, to override the schedule, or to hold a set temperature conveniently through the main Home screen.

Its switch icon is located at the bottom right of the screen.


This Trane XL824 Thermostat review proves that this device is truly an impressive programmable thermostat.

However, we also understand why some owners would still be turned off with the price of the product.

After all, this unit is on the pricier end of the spectrum.

Hence, if you’re considering a unit made by a similarly trusted brand but is definitely more affordable, then we suggest taking a look into the RTH9580WF Smart Thermostat by Honeywell.

Like Trane, Honeywell is also a century-old brand in the industry, and just like the thermostat we featured here, this unit also sports a wide, colored touchscreen that you can actually customize the color of!

The RTH9580WF can also be linked to your digital devices via Wi-Fi through a partner app.

The main difference, though, is that this product has fewer features compared to the XL824; you can say goodbye to your real-time diagnostics and live weather feed.

On the flip side, you can get an equally high-quality product for a significantly lesser price.


It’s no secret how much we like the Trane XL824 Thermostat.

Investing in this unit is totally worth the money spent with all the features included with it and the 10-year warranty thrown in by Trane.

In the end, we hope that we were able to provide you with the info you need about the product to make a clever purchase.
