Gree Heatpump with Gree KX75 control panel - how to wire in Nest 3

[AndrewC2]

Hi  I have a Gree heatpump with a KX 75 panel

The Kx75 wired panel has 2 connections  - H1 and H2. 

The wires running to the connections are twisted pair - orange/white and blue/white

As its a heat pump its heat, cool ,dehumidify etc. 

What is the right wire locations on the Nest 3 plate .
