Is My Heat Pump compatible with Nest

I have an older Trane heat pump.  Don't think I have my Nest Thermostat wired correctly.  Old thermostat had Red, Orange, Yellow, Green, and Blue wires hooked up to R, O, Y, G, and B.  The Nest thermostat I have Red to RH, Orange to OB, Yellow to Y1, Green to G, Blue to C, and White to W1.  Thinking I need to move the Red to RC and disconnect the White wires.  Can someone confirm that should work?  The Nest thermostat comes on with the current wiring setup but the heater blows cold air.   Another issue is that Google Home can't connect to the thermostat.

TIA!
