How do I access the Install/Service menus on the Infinity Thermostat?

Press and hold the ADVANCED button for at least 10 seconds to enter the INSTALL/SERVICE menus. The menu will automatically exit after 60 minutes of no button activity. From this menu, you can access Equipment Summary, Install, Setup, Checkout, and Service options to view system information, add or change equipment, modify settings, test equipment operation, and view fault history.
