How to Use Set, Hold, and Run on Your Thermostat?

If you’ve ever looked at the buttons on your thermostat and wondered what “Set,” “Hold,” and “Run” actually do, you’re not alone. These three features are small but powerful tools that can help you keep your home comfortable while saving on energy costs.

In this guide, we’ll walk you through what it means to set, hold, run your thermostat—and how using these functions the right way can make your heating and cooling system work smarter, not harder.

What Does Set, Hold, Run Mean on a Thermostat?

Modern programmable thermostats allow you to customize how and when your heating or cooling system runs. That’s where set hold run comes in:

• Set – This is where you create your heating and cooling schedule based on your daily routine.

• Hold – Temporarily locks in a temperature, overriding your usual program until you turn it off.

• Run – Returns the thermostat back to your normal programmed schedule after you’ve made manual changes.

When you understand how to set hold run effectively, you gain better control over both your comfort and energy usage.

How the “Hold” Function Works and When to Use It

The Hold button is perfect when your plans change. It lets you pause your usual schedule and keep a single temperature running for as long as needed.

When Should You Use “Hold”?

• You’re home on a day you’d normally be out.

• You’re going on vacation and want to maintain a consistent, energy-saving temperature.

• You’re dealing with a heatwave or cold snap and need to temporarily override your schedule.

How to Use “Hold”:

1. Adjust the temperature to your liking.

2. Press the Hold button.

3. Your thermostat will now maintain that temperature until you change it or hit Run.

Adding “Hold” into your set hold run routine makes it easy to stay comfortable without constantly reprogramming your settings.

What Does the “Run” Button Do?

The Run button brings your thermostat back to its scheduled programming. This is especially useful after you've used “Hold” or made a one-time change.

Use “Run” When:

• You're back from a trip and ready to resume your normal routine.

• You've hosted guests and want to return to your everyday temperature settings.

• The weather has returned to normal after a few days of extreme conditions.

How to Use “Run”:

• Just press the Run button and the thermostat will pick up where your schedule left off.

This final step in the set hold run process is key to restoring your system’s energy-efficient operation.

Why Set, Hold, Run Helps Save Energy

Each part of the set hold run process plays a role in saving energy:

• Set makes sure your HVAC system only runs when it needs to.

• Hold prevents overuse when you're not following your usual schedule.

• Run gets you back on track so your system runs efficiently again.

For even more control, consider using a smart thermostat that can learn your habits and make automatic adjustments.

Does Every Thermostat Support Set Hold Run?

Most newer programmable thermostats include set hold run features, but if you’re using an older model, you might not have access to these tools. Upgrading to a modern or smart thermostat can offer better control, comfort, and long-term savings.

Common Mistakes to Avoid with Set Hold Run

Even though it’s simple to use, it’s easy to make a few mistakes when using these features:

• Leaving “Hold” on too long, causing your system to run constantly.

• Not using “Hold” during extended absences, leading to energy waste.

• Accidentally hitting “Run” too soon, undoing a needed temperature change.

By understanding how to properly set hold run, you’ll get the most out of your thermostat and avoid these common issues.
