A basic WiFi Reset can be performed by removing the thermostat face plate from the wall plate and reattaching it after 30 seconds. The thermostat will attempt to connect to the WiFi signal is was previously paired with. To connect to a new WiFi signal, follow step 1 outlined below to disconnect or “forget” the old WiFi network and connect to the new network.

Step 1 – Connecting your mobile device to the thermostat’s WiFi network (NewThermostatxxxxxx)

Once installed and configured, the thermostat will display “WiFi Setup”. Open the Settings – WiFi on your mobile device and connect to the WiFi network named “NewThermostatxxxxxx”.

*If your thermostat does not display WiFi Setup, remove the thermostat faceplate from the wall plate for 30 seconds and then reattach it. If WiFi setup does not display, enter the Installer Setup (press and hold the fan and up arrow simultaneously for 5-10 seconds until the screen changes) and use the RTH6580WF1 User Guide here (or TH6320WF1 Install Guide here) to navigate the settings to function 38. Make sure function 38 is set to 1, then proceed to function 39. Use the up or down arrow to change function 39 function to 0 then press done. WiFi setup will then be displayed on the screen.*

Step 2 – Connect the thermostat to your home WiFi (via an internet browser on your mobile device)

After connecting to the thermostat WiFi (NewThermostatxxxxxx), open a web browser (Safari, Chrome, etc.) You should be automatically guided to a page titled “Thermostat WiFi Setup. If you are not automatically guided there, enter the IP address: 192.168.1.1 into the address bar on your browser to navigate there manually.

You should see your Home WiFi network listed. Select it and enter your WiFi password. After a brief connection period, your thermostat will display a “Connection Success” message. Reconnect your phone to your home WiFi network if your device does not reconnect automatically.

*If you do not see your home WiFi network, refresh the list. If your WiFi network is still not displayed, check the Trouble Connecting? / WiFi network recommendations*
