Perhaps you are moving but leaving your Honeywell smart thermostat at the old location. Or, you wish to sell it to someone else at a different location. Or maybe they have a different TCC account to assign the thermostat to. But in any case, please run through the unregister Honeywell WiFi Thermostat RTH9580WF process. Do this at the My Total Connect Comfort (TCC) web site, to save time and aggravation for the next person to own it. To make that easier, we show how to correctly unregister Honeywell Wi-Fi thermostat from the TCC web site. This unlinks it from its current TCC account.
If you do not unregister, your buyer will have to jump through some painful hoops to add this thermostat to fully access it. They may even pester you to unregister it. So take a few moments and unlink the thermostat from your own TCC account before giving it to a new owner.
How to Unregister Honeywell WiFi Thermostat RTH9580WF
1. Visit the Honeywell Total Connect Comfort Web Site
Direct your web browser to https://www.mytotalconnectcomfort.com/
2. Log In There
Enter your TCC user Id and password on the login page shown above. Then tap / click the red Login button.
When we do it, we get the device status screen for our sole thermostat, as shown next.
3. Tap or Click the My Locations Link
Find the My Locations link near the top of the page. It’s close to the left edge, as pointed at by the pink arrow in the previous picture.
This brings up a list of all the locations / physical addresses that you’ve set up in your TCC account, as follows.
4. Tap / Click the Settings Link for the Location to Change
To unregister a particular thermostat, edit the location in which the thermostat has previously been registered. In our case, we only have one location; the My Apartment locale. So, it is those settings we’ll edit here.
Activating the Settings link brings up the Edit Location page, as shown next. Note that we’ve “spray painted” the sensitive details about our personal TCC account, in pink “paint”.
5. Tap the Trash Can Link
Tap the Trash Can link for the thermostat you wish to unregister at the location you’re editing. Find the list of registered thermostats at this location in the right lower quadrant of the page. It’s in the Devices Assigned to this Location section. The pink arrow in the previous picture points to the trash can we’re referring to.
6. Tap / Click the Red Yes Button
This action briefly displays the Deleting Thermostat page while it unregisters the selected thermostat, as shown next.
After this de-registration is finished, the site then returns you to the Edit My Location page, as shown next. Notice that the thermostat we unregistered is no longer listed in the Devices Assigned to This Location section.
7. Check that your Thermostat is Now Unregistered
Verify this by going to the thermostat itself, and inspecting its home screen. As shown next, when a Honeywell 9000 series Wi-Fi thermostat is not currently registered, it displays a message in a yellow box. This prompt invites you to register the thermostat to control it remotely. If you see this message, then it has been successfully unregistered. Thus, a new owner can register it in their TCC account, without needless difficulty.
After de-registration, the thermostat still works correctly. E.g. It continues regulating the temperature and following its schedule if set. Plus, you still can control it locally making adjustments to temperature and schedule as well. But the thermostat will no longer be accessible remotely via the Honeywell Total Connect Comfort web site, until iregistered again.
Caution. Keep in mind that unregistering the thermostat does not reset it to factory default values. All your local settings changes, including programs, schedules, and preferences, will remain intact. Nor does resetting the thermostat unregister it. While resetting may erase any settings customization, the thermostat remains linked to its current account until iexplicitly unregistered by the account owner on the TCC web site. So, to prepare the thermostat for its next owner, we strongly suggest not only unregistering it online, but also resetting it to factory default settings locally.
