I accidentally pressed "Remove Home". What do I do now?

From the removed thermostat, login using your Lennox S40 credentials under Menu > User Account. Logging in will automatically add the Lennox S40 Smart Thermostat to your account again. You will be prompted to re-enter the home address.

Note: If there was more than one thermostat registered in the home at the time it was removed, you will have to repeat this process for every thermostat.
