Shows how to register Honeywell thermostat models online, on the Honeywell Total Connect Comfort (TCC) site.
How to Register Honeywell Thermostat: Prerequisite Steps
1. Install your the Thermostat
Firstly, skip this step if you already installed your t-stat and it is showing its Home screen. But if you haven’t, see our Honeywell Smart Thermostat Wiring Instructions RTH9580WF post. This offers tips on mounting and wiring this new thermostat.
2. Connect It to your Wireless Network
Then skip this step if you’ve already done this. But if you haven’t, then see our Change WiFi Network on Honeywell Smart Thermostat RTH9580WF piece. This gives tips on how to link the t-stat to your home or office network.
3. Create an Account on the Honeywell Total Connect Comfort (TCC) Web Site
Thirdly, you’ll need a working account over there to register and control your t-stat remotely. Again, skip this step if you’ve already set up a TCC account. If you have not, then visit the TCC web site here. Then on the login page, click the Create an Account button, and follow the instructions.
4. Gather the T-stat Info to Continue with How to Register Honeywell Thermostat
So to add your t-stat to your TCC account, you’ll need its MAC address and CRC code. Find this info printed in the manuals that come with a new t-stat. But you may also get it from the t-stat itself, as follows. But if you have this data already, then skip down to Step 5.
How to Register Honeywell Thermostat: Step by Step
5. Look at the Home Screen

6. Tap the Yellow Message Box
Then find this on the left center of the screen.
So this brings up a Notification screen. This tells you that you must register the thermostat online.
![Picture of the Honeywell RTH9580WF thermostat. Displaying a Notification screen that says that you must register the thermostat. Plus it shows the -Wi-Fi Setup- button.](https://i0.wp.com/tomstek.us/wp-content/uploads/2017/03/HoneywellRTH9580WFNotificationRegistrationNeededWiFiSetupHighlighted_001.jpg?resize=300%2C223&ssl=1)
7. Tap the Wi-Fi Setup Button
So the Wi-Fi Setup screen displays then, as shown next. Note that in this demo, we connect the t-stat to our 937T681J4059H_2G WiFi network. But nonetheless, it is as of yet, unregistered. Thus you should connect to the network you used in Prerequisite Step 2 above.
Also, we “pink-painted over” our thermostat’s MAC address and CRC value in these pictures for security reasons.

Finally, stop here. You have now registered your thermostat. So, you may now control it via the internet and the TCC web site or app.
Fixing Problems
Finally, perhaps you received an “already registered” message as you follow the steps above. Then in that case, you’ll need either to,,,
-
- Contact the previous owner of the thermostat (if you bought it used). Then ask them delete that device from their TCC account.
- Or if you cannot do that, call Honeywell customer service at 1-855-733-5465 for assistance.
