Is my thermostat compatible?

Can anyone confirm if attached wiring is compatible with NEST, this is how it is wired in my carrier thermostat.

The humidifier makes your system only compatible with the Nest 3rd Gen Learning Thermostat.

You can wire it like this.

White - W/W1 to W2

Yellow - Y / Y2 to Y1

Green - G to G

Red - R to Rc

Orange - O/W2* to OB

Blue - C to C

Black - HUM to * (set as Humidifier)

Brown - S1 - not used
