Honeywell is a trusted name when it comes to quality thermostats, with a reputation earned over many years.
Just as with any electronic gadget, though, thermostats can sometimes hit a snag. You might find your Honeywell thermostat having a tough time connecting to your Wi-Fi or not maintaining the temperature you’ve set for your home.
If you hit a speed bump with your thermostat, one of the easiest fixes is to give it a good old reset. This wipes all user information from the device, taking it back to factory settings, and helping to eliminate any odd software glitches that could be causing issues.
Trust me, I’ve lost count of the number of times a quick power cycle or a hard reset has solved problems with my thermostat and other devices.
It’s always my first line of defense before I look at other troubleshooting options.
Most Honeywell thermostats make the reset process fairly straightforward, though some of the older models might need a bit more elbow grease.
In this guide, we’ll walk you through how to identify the model number of your Honeywell thermostat and explore the different types of resets available.
I’ll also provide step-by-step instructions to reset your device based on its specific model.
The CleverFix:
If you’re looking to reset your Honeywell thermostat, different models have different methods. First, find out which Honeywell model you have. Then, scroll down to see whether a reset involves a simple button push or a deeper dive into the thermostat’s settings.
Finding the model number of your Honeywell thermostat
Before you proceed with any reset, you need to identify your Honeywell thermostat’s model number.
You can usually find this on the product ID card that came packaged with your device.
Misplaced the ID card? No worries. You can also spot the model number on the thermostat itself.
Typically, it’s displayed on the front faceplate. If not, take the device off the wall, flip it over, and you should find a label on the backside detailing the model number and date code.
Once you know your thermostat model, you’re set to dive into the steps below.
How to reset Honeywell thermostat
You can reset your Honeywell thermostat in different ways, and the one that will work best depends on what issue you’re trying to solve with your device. These resets include:
- Hard reset
- Wi-Fi reset
- Schedule reset
- HomeKit reset
Hard reset
A hard reset is like taking your Honeywell thermostat back to its ‘out-of-the-box’ state—it clears all your settings, data, and preferences, including programmed schedules. This type of reset is handy for tackling problems like faulty controls, software glitches, or calibration issues.
To do a hard reset, you’ll need to access the thermostat’s programming menu, but steps might differ from model to model.
Wi-Fi reset
Doing a Wi-Fi reset is a bit like giving your thermostat a fresh start at connecting to your Wi-Fi network—it deletes all the current Wi-Fi settings. Perfect for when your device is struggling to connect to your internet.
Schedule reset
Opting for a schedule reset wipes out all of your thermostat’s programmed schedules. It’s the ideal reset if you wish to start from scratch with a new heating or cooling timetable.
HomeKit reset
A HomeKit reset will wipe out all thermostat settings linked to HomeKit. It’s important to note that this feature isn’t found on all Honeywell thermostats, only on newer models like the Honeywell T9 and T10.
This reset can be a big help if you’re running into issues with your thermostat’s HomeKit functionality or if you plan on passing your thermostat onto someone else.

Once turned on, the thermostat should revert to its default factory settings.
