question about upgrading Smith Gates Thermostat

I have in floor heat controlled by a 10+ year old Smith Gates thermostat and want to upgrade to something with a timer, even better something with a wifi option. the old one has what I assume is a thermocouple (single thick bare copper lead embedded in the body of the thermostat that I assume goes down the wall and ends up embedded in the tile floor somewhere. The only other wires are the 240v power leads. Can anyone suggest what my options are please?
