Sometimes though, adjusting the setting doesn’t seem to help. If no matter how much you adjust the thermostat, you can’t get comfortable, you may need to reset it.

Below we’ll show you how to reset your Honeywell thermostat. In fact, we’ve dug through the manuals of the most popular models so you don’t have to. Read on to learn more.

How to Reset a Honeywell Thermostat: All Models

There are several ways you may want to rest your thermostat, depending on its capabilities and the problem you’re trying to remedy. Here are the types of resets you may want to do:

  • Factory reset. This is the most common type of reset. It returns the device to the original settings when it came from the factory.
  • Wi-Fi Reset. If you have a Wi-Fi-enabled thermostat, this reset will cause it to forget the Wi-Fi network it’s using.
  • Schedule reset. This will erase the schedule you are using to control your thermostat.
  • Model-Specific Resetting. Depending on the kind of Honeywell thermostat you have, you will use a different technique to reset it. Identify the thermostat model by looking at the front of the unit or checking the manual that came with it.

Caution:  Some of these thermostats are connected directly to household electric current. If you can’t identify the model or aren’t knowledgeable about working with household wiring, call an HVAC pro before doing any work that would expose you to the wiring. 

If you make a mistake, there is a danger of electric shock, which could cause injury or even death. However, most of these resets can be done by simply using the built-in controls without any risk.

  • Factory reset. This is the most common type of reset. It returns the device to the original settings when it came from the factory.

How do you manually reset a thermostat?

To manually reset a thermostat, first turn off your thermostat using the power control switch. Then, turn off the breaker on your electrical panel. Wait about a minute, and then turn both back on. This should give the system time to reset. If this does not work, you might have a faulty thermostat.

What is wrong with my Honeywell thermostat?

If your Honeywell thermostat is malfunctioning, it's likely not holding the desired temperature. The batteries could be low if the screen is flashing or the buttons don't work. If the screen looks fine, you might have a bad temperature sensor, at which point it's best to replace the entire thermostat.

How do you reset the battery on a Honeywell thermostat?

To reset the battery on a Honeywell thermostat, first ensure that the thermostat is turned off. Then, open the battery door and take out the batteries. Put them back in as indicated on the back. Then, let the thermostat sit for about a minute to give it time to reset.

What is hold on a Honeywell thermostat?

The "hold" button on a Honeywell thermostat locks the temperature to the desired setting (or in some cases the current temperature) until you press the "run" button, which will return the thermostat to its programmed schedule.

Resetting a Honeywell Thermostat: Final Thoughts

If the resetting doesn’t fix the problem, or you don’t want to use one of the methods that could expose you to electricity, you can find an authorized repair shop by calling Honeywell Home support at 855-733-5465.

However, once you’ve identified which thermostat you have, the resetting process is not that complicated. And resetting will often help your thermostat return to quietly doing its job of keeping you comfortable.
