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”.

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.

8.  Done!

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.
