Hi Joanna4,
Thanks for posting here in the Community forum and for showing interest in our Nest Thermostats. Fortunately, your thermostat wires are compatible with our Nest Learning Thermostat 3rd generation since you have second stage of heating and cooling. Your thermostat wires should be wired to the Nest Learning Thermostat base as shown:
Take not that jumper wire is not needed for Nest Thermostat. Also, here's a guide for the installation and setup of a Nest Learning Thermostat.
Let us know if you have any other questions.
Best,
Zoe
