Changing out a thermostat

I currently have a Trane and am swapping for a CetraLite Zigbee HA Thermostat. I am looking at the posts and the lettering does not seem to match up. Here are the ones I see on the Trane:

R -- has a wire
W2/Y2 -- no wire
W1 -- has a wire
Y -- has a wire
G -- has a wire
O -- no wire
B -- has a wire

On the new unit I have as choices:

C, Y1, G, W2, W1/B, Y2/O, RC, RH, I1, IC

Can someone please tell me what goes where?

Thanks

G to G
W2 no wire
W1/B would be W1 on old stat
Y2 no wire
RC and RH would be R wire on old
