Most AC units are cooling only. Unless it is actually designed as a bi-directional heat pump, you can't make it go backwards.
good point, I think it also needs a special valve that reverses the flow of the "freon". I have seen similar units (same model) in a previous condo complex where there was no gas heat, so I know this outside unit can also work as a heat pump. I don't know if there is a valve, and if the inside furnace can handle it.
