2GIG Thermostat removal?

I am trying to remove the thermostat from my system. May I have help or direction please.

Similar to the addition process, to remove a Zwave device, go to your panel and access your Zwave toolbox by pressing Services, Zwave, the lower right Wrench icon, installer code. Select Remove Device, then follow the standard pairing process on the thermostat. (on a CT100 that would be Menu, then “Mate” twice.

Will this remove the item from my Alarm.com interface?

After a short period, yes. If you have multiple thermostats, this will be no longer accessible from the drop down menu. If you only have this one, your thermostat page will be empty.
