Go here and download the Control 4 driver.

[Link: drivers.control4.com]

rename the file to .xml and then open in a text editor.

Search for 0000 0067

There you will find the Pronto Hex as officially used by Control 4.

My recommendation would be to test 1 or 2 codes. Start with line 1557 of the file
