How do I connect my RTH6500WF Smart Series Programmable Thermostat to WiFi and register it?

Last updated



Connecting your thermostat to Wi-Fi can be performed during the initial setup and configuration, or later at a time you choose.


Connecting to Wi-Fi – Initial Setup:


After the Configuration step during the initial install, you will be prompted to connect your FocusPRO Wi-Fi 6000 to your Home Wi-Fi.

The FocusPRO Wi-Fi 6000 uses a 3-step connection and registration process

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

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

Step 3 – Register your thermostat in the My Total Connect Comfort web portal.

*Registration cannot be performed with the mobile app, currently only supported via the web portal*

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. Return to step 1.*

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: 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 below.*

Step 3 – Register at

Registration is completed at Navigate to the page and create an account / login. You will be prompted to create a “Location” to associate your thermostat with, if you do not have a location already in your account.

Select the “Add Device” icon and Input the MAC ID / CRC for your device. (MAC ID / CRC are located on your thermostat information card, on the back of the thermostat.

Complete the security check (if prompted) and follow the directions within the web portal to complete the registration.

Unable to Register:

If your device connects to Wi-Fi, but fails to register, it may already be registered to another user. If known, contact the previous owner and ask that they delete the device from their account. If the previous owner is not known, contact resideo Customer Care to unregister your device. You will require the MAC ID (located on the back of your product) to complete the un-registration process.

Wi-Fi Reset:

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 above to disconnect or “forget” the old Wi-Fi network and connect to the new network.
