Stranded wire is not compatible with the Nest terminals and usually signifies that there is line voltage (120vac) present which isn't compatible either.

Can you post a picture of the original thermostat's wiring here?

It won't let me upload a picture but I think my condo unit uses a high voltage HVAC system.
