Configuring during initial setup:

When powered, after setting the time and date, the thermostat will display 2 sets of numbers, one set on the left of the display and one set on the right. Use the User or Installation Guide to configure your thermostat for your system.

After finishing the setup, the thermostat will control your heating and cooling system normally.

Wi-Fi – After installing your thermostat, Wi-Fi Setup will display on your thermostat screen (TH8320WF / RTH8580WF) This indicator means your thermostat is broadcasting it’s own Wi-Fi network and is ready to be paired.

Or, your thermostat will prompt you to connect to Wi-Fi at the end of the setup (TH8321WF).

Connect to the mobile app / web portal – After Connecting to Wi-Fi you can register your thermostat at www.mytotalconnectcomfort.com/portal. Create an account, login and add your thermostat by inputting the MAC ID / CRC (located on your thermostat information card, or on the back of the thermostat])

Reconfiguring your thermostat:

At any time, the configuration of your thermostat can be modified from the Installer Setup of your thermostat. Access the Installer Setup by pressing the System button and holding the center blank box at the bottom of the thermostat for 5-10 seconds until the screen changes (TH8320WF / RTH8580WF). On the TH8321WF, select the Menu > Installer Options, then enter the Date Code (located on the back of the thermostat or from the Menu >Equipment Status screen). Use the User or Installer Guide to navigate / modify the settings.

*Modifying your system configuration can cause improper operation. Verify you fully understand your system type before reconfiguring any settings.*
