If you?re getting a Connection Failure message on your FocusPRO (TH6320WF, RTH6580WF, or TH6210WF) thermostat, it probably lost internet connection. Please follow the steps below to remedy the issue.

*If your thermostat has lost WiFi connection, you will be required to be on-location with the thermostat to reconnect it manually. For some users, a reconnection may be possible by remotely re-starting your WiFi router. Check with your internet service provider for possible options.*
To reconnect your device to WiFi:
- Make sure your router is online.
- Go to your thermostat on the wall and remove it from its base.
- Wait for 1 minute.
