I did this on Aprilaire 8870 in a house with radiant baseboard and forced air conditioning. As I recall it was as simple as a couple of settings in the menu and leaving off the jumper between R and RH
I've done the same with radiant in floor and an 8870.
If you end up using separate t-stats, Houselogix has a driver that will combine them into a single t-stat on the UI's.
