Reset for All Trane Thermostat Models

This step-by-step reboot procedure applies to all Trane thermostats.

1. Ensure Your HVAC System Is Idle Before the Reset

Ensure your HVAC system is idle; this helps prevent any potential damage during the reset process. When your HVAC system is active, pressure build-up is managed through the valving system. 

Attempting to reset an active HVAC system could lead to an increased pressure load that can damage your HVAC’s internal workings.

2. Find the Switch Connecting to Your Thermostat

If you’re having trouble finding the switch to your Trane thermostat, don’t worry – it’s probably just hidden in your breaker box. The breaker box is usually located in a basement or utility room and houses all the switches for your home’s electrical system.

Here’s a YouTube video that explains how to find the right switch for your appliance in the breaker box:

3. Turn the Switch to the OFF Position

Turn the switch to the “Off” position; Most people don’t know this, but when you reset your thermostat, it’s important to turn off the switch in the breaker box. Otherwise, you could be in for a nasty shock. 

When you turn off the power to your thermostat, you also turn off the power to the sensors. These sensors tell the thermostat when to turn on and off. If you don’t turn off the power to the sensors, they can become overloaded and cause damage to your thermostat.

Here’s a step-by-step guide on how to reset a Trane Thermostat for models XL824/850/1050.

1. Ensure Your HVAC System Is Idle Before Continuing

Just like all the regular models, the Trane XL824/850/1050 models must be put into idle mode before a reset to prevent potential pressure damage. The idle mode also ensures that your system’s circuits are protected from any damage that may occur while resetting your thermostat.

After tapping the menu button, select “Settings” from the options displayed on the screen. The settings menu is typically found in the upper-left corner of the screen

4. Wait for the Thermostat To Reboot

A Trane thermostat can take anywhere from minutes to reboot. However, the average time it takes to reboot is between 2-3 minutes. If your Trane thermostat takes longer than 3 minutes to reboot, you may have an issue with your unit. In that case, you should call a professional to check it for you.
