Power off your furnace or heating system. This ensures a safe installation.
Either at the breaker panel or on the shutoff switch.
Set a temperature on the existing thermostat that should trigger heating or cooling. Wait 5 minutes and verify the system did not come on before proceeding.
Keep Your Tools Ready.
All you need are a Phillips-head screw driver and a wire stripping pliers.
Remove your old thermostat faceplate. If you see thick black wires and wire nuts, your system is not compatible and do not proceed. If you see thin colored wires, then take a photo of the backplate to show the colored wires and the labels of the thermostat terminals each is connected to.
Make sure to pull the wires out of the barrels and from the wall before unscrewing the backplate. You may need to wrap the wiring around a pencil or other large enough object to keep the wires from falling back behind the wall.

Feed the colored wires through the back off the backplate and connect the wires to barrels according to the colors.
