How to Register Honeywell Wi-Fi Thermostat Online for Remote Control, RTH9580WF




In order to control your Honeywell Wi-Fi thermostat remotely, you’ll need to register and connect to it at the   Honeywell Total Connect Comfort (TCC)   web site.  Here, we demonstrate how we registered our 9000 series RTH9580WF wireless thermostat, on that site.

 

Prerequisite Steps

1. Install your Honeywell Wi-Fi thermostat.  Skip this step if you’ve already installed your thermostat and it is powered on, and showing its home screen.  If you haven’t, see our Honeywell Smart Thermostat Wiring Instructions RTH9580WF post for tips on mounting and wiring this new thermostat.

 

2. Connect your thermostat to your internet-enabled Wi-Fi network.  Skip this step if you’ve already connected your thermostat to an internet-ready Wi-Fi network at its installed location.  If you haven’t, then see our Change WiFi Network on Honeywell Smart Thermostat RTH9580WF piece for instruction on how to link your thermostat to your home or office wireless network.

 

3. Create an account on the Honeywell Total Connect Comfort (TCC) web site.  You’ll need a working account over there in order to register your thermostat and control it 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, and on the login page, click the  Create an Account  button, and then follow the instructions.

 

4. Gather the necessary thermostat information.  In order to add your thermostat to your TCC account, you’ll need its MAC address and CRC code.  This information is printed in the documentation that accompanies new Honeywell thermostats.  However, you may also obtain it from the thermostat itself, as follows.  If you have this information already, then skip ahead to Step 5 below.

4a. Look at the thermostat Home screen, as shown next.

4b. Tap the yellow message box   on the left center of the screen, as shown in the previous picture.  This brings up a notification screen, as shown next, that indicates that an online registration is needed.

4c. Tap the   Wi-Fi Setup  button.   The   Wi-Fi Setup  screen displays then, as shown next.  Note that in our scenario, the thermostat is connected to our 937T681J4059H_2G wireless network, though it is as of yet,  unregistered.  Yours should be connected to the wireless network you pointed it at in Prerequisite Step 2 above.

We’ve “pink-painted over” our thermostat’s MAC address and CRC value in these pictures.

4d. Write down CRC and MAC address displayed on your thermostat.  You’ll need these values in the following steps to complete the registration.

 

5. Visit the   Honeywell Total Connect Comfort   web site.  On your computer, phone, or tablet, point your web browser at https://www.mytotalconnectcomfort.com/ .   You’ll then see the login screen similar to what we got, as shown next.

6. Enter your TCC account user name and password.

 

7. Press the red    Login   button.  If this is the first time you’ve signed into the TCC web site, and you’ve never set up any locations before, then you’ll see the following screen, and will have to set up at least one location to register your thermostat in.  We detail how to do that in the steps immediately following.

But if you already have defined the location where you’ve installed your thermostat, then it will be listed on the  My Locations   screen, as shown in the next picture.  Skip ahead to step 8 in that case, to continue the registration process.

7c. Tap the red   Submit   button.   The site then displays the   Register Device   page, as shown next.  From here, jump down to Step 9 to complete the rest of the registration process.
