Can I use misting, fogging, and soaking in a THI controlled equipment group?

Yes! THI misting/fogging/soaking looks exactly the same as in a cooling equipment group, only you will have THI values as the low/high/max setpoints rather than temperature values.
There are three videos explaining the three modes available in the AFX:
