Unregister Honeywell Thermostat RTH9580WF

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 t-stat 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 for the next person to own it.  To make that easier, we show how to fully unregister it.  This  unlinks the t-stat from your TCC account.





If you fail to unregister, your buyer will have to jump some hoops to register it in their account.  They may even pester you to unregister it.  So take the short time to unlink the t-stat from your own TCC account before selling it to someone else.

To unregister a certain thermostat, edit the location where you registered it.  In our case, we only have one address; the  My Apartment  locale.  So, it is those settings we’ll edit here.





Clicking 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”.

7. Check that your Thermostat is Now Unregistered

Verify this by going to the t-stat itself, and look at its Home screen.   As shown next, when not registered, it shows a message in a yellow box.  This prompt invites you to register the thermostat to control it remotely.  If you see this, then you have indeed fully unregistered it.  Thus, a new owner can register it in their TCC account, without needless hardship.

8.  Done with Unregister Honeywell Thermostat RTH9580WF Instructions !

After de-registration, the t-stat still works.  E.g. It still controls the temperature and follows its schedule if set.  Plus, you still can adjust it locally.  But you can no longer access it remotely until you register it again.

Caution  

Keep in mind that unregistering the t-stat does not reset it to factory default values.  All your local settings changes, like schedules, and preferences, remain.  Nor does resetting the thermostat unregister it.  Resetting clears settings,  yes. But the t-stat still links to its current account until unregistered by the account owner on the TCC web site.  So, prepare the t-stat for its next owner the right way. We strongly suggest not only resetting it to factory default settings locally, but also unregistering it online as well.
