How do I change or reset the WiFi connection on my RTH6500WF Smart Series Programmable Thermostat?

A basic Wi-Fi 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 Wi-Fi signal is was previously paired with. To connect to a new Wi-Fi signal, follow step 1 outlined below to disconnect or “forget” the old Wi-Fi network and connect to the new network.

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

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

*If your thermostat does not display Wi-Fi Setup, remove the thermostat faceplate from the wall plate for 30 seconds and then reattach it. If Wi-Fi 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 Wi-Fi (via an internet browser on your mobile device)

After connecting to the thermostat Wi-Fi (NewThermostatxxxxxx), open a web browser (Safari, Chrome, etc.) You should be automatically guided to a page titled “Thermostat Wi-Fi 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 Wi-Fi network listed. Select it and enter your Wi-Fi password. After a brief connection period, your thermostat will display a “Connection Success” message. Reconnect your phone to your home Wi-Fi network if your device does not reconnect automatically.

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