It is very hard to give you an accurate answer without a picture of the old thermostat wiring, but try the following it should work:
- Red to Rc or R.
- Blue to Y1 or Y
- Green to G

Thanks, which Nest thermostat I should buy

The Nest thermostat 2020 (the one with the mirrored faceplate) is usually cheaper and should work fine for your use case.
