How to Register Honeywell WiFi Thermostat

Shows how to register Honeywell WiFi thermostat models online, on the Honeywell Total Connect Comfort (TCC) site.

How to Register Honeywell WiFi Thermostat: Prerequisite Steps

1. Install your the Thermostat

Skip this step if you already installed your t-stat and it is showing its Home screen.  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 Ut to your WiFi 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 WiFi 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 WiFi 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.

5. Look at the  Home Screen

6. Tap the Yellow Message Box

Then find this on the left center of the screen, as shown in the last picture.

So this brings up a Notification screen. This tells you that you must register the thermostat online.

7. Tap the   Wi-Fi Setup Button

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 WiFi 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.

8. Write Down CRC and MAC Address Shown to Continue with How to Register Honeywell WiFi Thermostat

Then you will need these values from your t-stat in the steps next, to register it.

9. Visit the   Honeywell Total Connect Comfort   Web Site

So point your web browser at https://www.mytotalconnectcomfort.com/ .

You’ll then see the login screen.

10. Enter your TCC Account User Name and Password

You’ll see the next screen if all conditions below are true.

1. 1. This is the first time you’ve signed into the TCC web site
   2. You’ve never set up any locations before.

Furthermore, at that screen, you must set up at least one location in which to register your thermostat.  We detail how to do that in the next steps.

But if you already defined this location, then that will appear on the  My Locations   screen.  So skip ahead to step 12 in that case, to continue.

11a. Tap the Black   Add Location   Button to Continue with How to Register Honeywell WiFi Thermostat

The    Add Location  screen then displays, as shown next.

11b. Type in the Info Asked For About the Location you Want to Define

So in our demo, we define a location named Graystone.  Enter the location’s name, physical address, region, city, state. But don’t forget to choose the location type (home or building).

11c. Tap the Red   Submit   Button

Then the site displays the   Register Device   page.  From here, jump down to Step 9 to continue.

12.  Tap the   Settings   Button  on the Already-Defined Location

Following, you’ll then see the   Edit My Location   screen.

13. Tap the Black   Add Device   Button to Continue with How to Register Honeywell WiFi Thermostat

Find this near the lower left corner of the screen.

This then brings up the   Register Device   screen.

14. Enter the MAC Address and CRC Value you Wrote Down in Step 4 Above

15. Tap the Red   Submit   Button

The system then briefly displays the   Device Registration In Progress   screen as shown next.

So after a few seconds, you get the  Thermostat Registration Successful   screen, as follows.

16. Tap the Black   View   Button

This takes you then to your thermostat’s status screen.

17. Done with How to Register Honeywell WiFi Thermostat !

Finally, stop here.  Registration is now complete. So, you may now control the Honeywell WiFi thermostat  via the internet and the TCC web site or app.

Fixing Registration Problems

Finally, perhaps you received an “already registered” message as you follow the steps above. Then in that case, you’ll need either to,,,

1. 1. Contact the previous owner of the thermostat (if you bought it used). Then ask them delete that device from their TCC account.
   2. Or if you cannot do that, call Honeywell customer service at 1-855-733-5465 for assistance.
