Need help with wiring

Hi everyone, I am trying to replace my cor7 thermostart with a new Nest Thermostart. This is the current setup in my cor7:

O/W2/B: Brown wire

G: Green Wire

Y/Y2: Yellow Wire

Rc : Red Wire

C: Blue Wire

My A/C unit is Carrier Sentry 3-Ton 14 SEER R410A Heat Pump (208/230 V 1-Phase)

Please help. Thank you very much
