I have an airwolf 3d printer, my heated bed is not software controlled, it's just wired to a fixed 12v power supply. I'm using gen 6 electronics, and that does not support heated bed, I'll have to upgrade to a gen 6 deluxe if I want software heated bed. I'm using repetier host and firmware, and that will support a heated bed if I I upgrade the electronics. I could also put an independent temperature control on the bed... I just have to get a round to it. I may just get some PLA and try it non-heated.
