The home screen of your CT80 looks like the illustration below. To pair the thermostat to your Smart Controller, touch the button marked "Menu" on the lower right side of the unit as shown;
The menu will appear, as shown below. Touch the "Network" menu option.
The next screen will show you buttons to start the wireless "Network" connection you'll want to make to your Vera Smart Controller. Choose "Radio 1" for your system.
NOTE: All wireless devices use miniature "radios" in order to be wireless, so don't be confused by the term here. Since your CT80 can be operated by more than one wireless network, you'll see options for more than one radio. Don't worry, you only need one.
Now put your Vera Controller into "Battery" mode and bring it to within 3 feet of your CT80 thermostat.

If you're using a Vera3 Smart Controller, push the "Z-Wave" button on the front panel to put it into pairing mode. The green Z-Wave LED light will flash slowly -- Vera3 is ready for pairing.

The blinking light on your Vera Smart Controller will flash quickly to show the thermostat was paired to it, then return to blinking slowly. The CT80 will display the name of your network to show it was paired.
On the VeraLite, push the "+" button again and hold it for 5 seconds to save the pairing. On the Vera3, push the "Z-Wave" button and hold it for a count of 3. Now return your Smart Controller to its usual spot and plug the power and network cables back in.
