You might need to setup your Honeywell smart thermostat (t-stat) to the internet, by changing a new WiFi network. Perhaps you moved it, and the WiFi it ran on before is no longer in range. So in this post, we cover how to setup WiFi on a typical Honeywell thermostat, to join your unit to WiFi for the first time, or to get your t-stat working fully again on another network.
How to Setup WiFi on Honeywell Thermostat
For sure, Honeywell really improved the WiFi setup routine for their later model smart t-stats. Indeed, you no longer must set it up via a tablet or phone to update the WiFi network settings. Instead, you can do this right on the touchscreen menu system on many models. Here’s how.
1. Enter WiFi Setup mode
First of all, switch from normal to WiFi setup as follows. Press the Menu button at the top right of the Home screen, as shown above.
Then, scroll with the arrow keys at right, through the main menu. Stop scrolling when you see the WiFi Setup button, as shown next.
Next, press the WiFi Setup button, circled in red in the above pic. The WiFi setup screen then displays, as shown next. Note that we have blanked the t-stat MAC address and CRC values, to preserve its anonymity. Also note that normally, this screen shows the status of the setup WiFi network. But here, the OurHouse1 network is not in range (no signal). So we’re going to discard that info, and replace it with an in-range WiFi network in the following steps.
2. Disconnect the T-stat from its Current WiFi Network
Then press the Disconnect from Network button. The WiFi Network Disconnect Confirmation screen appears, as follows.
Press the green Yes button.
After a pause, the system lets you know that it disconnected from the old WiFi network, as shown next.
Then, press the green OK button in the lower right corner of the screen. This takes you back to the main menu, as shown next.
3. Find the WiFi Setup Button to Continue with How to Setup WiFi on Honeywell Thermostat
From there then, use the UP and DOWN arrow keys to scroll through the menu to the Wi-Fi Setup button.
4. Tap the WiFi Setup Button
Then, press the red-circled WiFi Setup button. When no network information resides in the t-stat, pressing Wi-Fi Setup starts a scan for in-range WiFi networks.
Then, a brief message displays, telling that the network scan is in progress.
Then, most Honeywell WiFi thermostats list the in-range networks they discover, on their Select Wi-Fi Network screen, as follows:
5. Find your Desired WiFi Network
Then, tap the network in the list to which you wish to setup the smart t-stat. So in our case, we’re setting up the thermostat on the 937T681J4059H_2G wireless network. The WiFi Password Entry screen then appears, as follows.
6. Enter WiFi Password if Asked For to Continue with How to Setup WiFi on Honeywell Thermostat
Next, use the displayed virtual keyboard to enter your password. Then, to enter numbers and punctuation characters, press the ?123 key. Why? Because this switches the keyboard to number entry mode.
The password characters appear as you type them. So do this when no one is looking.
7. Next, Join the WiFi Network you Picked
Once you enter the password characters, press the green Done button.
The thermostat then tries to connect to the chosen WiFi network. While setting up the link, it displays the following screen.
Then, if no errors happen, the system reconnects to the WiFi network you picked.
Then it displays the following screen. It shows the name of the wireless network that the t-stat now connects with.
8. Register your Honeywell Thermostat Online for Remote Access
Next, press the green OK button.
Then, the Register Online for Remote Access screen displays, as shown next.
Now perhaps you already registered your t-stat. If so, then you need not register it again, so long as you have not unregistered it. Note that setup on a new WiFi network does not unregister a Honeywell thermostat.
Then, press the green Done button.
The system then returns to the Wi-Fi Setup screen. But this time, the connected network settings appear, as shown in the next shot.
Next, press the green Done button.
Then, the t-stat takes you back to the main menu, as shown below.
Then from there, press the Home button at the top left corner of the Main Menu screen, to return to the Home screen, as shown next.
9. Done with How to Setup WiFi on Honeywell Thermostat !
Finally, your Honeywell thermostat is now joined to your working WiFi network. You’ll see that when the outdoor temperature and humidity settings update soon thereafter. So, you’ve successfully setup WiFi on your your Honeywell wireless thermostat.
