Hello audioplus,
Thank you for reaching out to the community. Based on your wiring system, most of them are compatible with the Nest thermostat. However some wires may require a professional's help for proper identification.
If you'd like to get better assistance with installation you can contact one of the recommended technicians.
Best regards,
Daniel
