How do I turn off the power to my thermostat?

Question

I'd like to replace my thermostat with a new one. My current thermostat is one that doesn't have a C-wire and is powered by batteries.

Now, my question is... is there a switch for the power that I need turn off too? I could not find a switch for the thermostat in the breaker box.

I'm assuming just removing the batteries is fine for replacing my thermostat?

Simply turning off the breaker that feeds the furnace will turn off the thermostat power as well.
