Arnold Volume only rendering Temperature with density, not heat value

Currently working on a project that requires me to export a Pyro VDB from Houdini and render it with Arnold. so far everything works perfectly, it animates, renders, supports the volume shader, etc.. The only issue I'm having so far is that temperature is only rendering with density, the same shader that drives the volumes smoke. The VDB is also exporting the heat and temperature values, but either of these do not work with the Temperature.

Anyone else had this issue? Is it to do with the way ive exported the VDB or is it an issue inside of Arnold? Or is this correct and I've done it correct, and its just not set up right?

Brilliant! That fixed it. I didn't know you could add more than a single field.
