AU - Controlling an LG 3 wire multizone ducted reverse cycle air conditioner

As the title suggests. I am in Australia and we have a ducted reverse cycle inverter AC bybLG. It is broken into 4 zones and I have searched the net but had no luck trying to find a controller or even a suggestion on a way to control and integrate this into my ZWave network…

Has anyone maybe seen or know of any suggestions for this task… which I would really have thought is everywhere… or are these type of heating and cooling solutions only in Australia??

Any help appreciated.
