I had a BMPlus 5000 (Version A) connected to a Carrier 3EYG060300 heat pump. The expansion board went out and after going thru some trial and error and discovering that the new XM2 Version B is not compatible with the BMPlus 3000 Ver A board. I purchased a new BMPlus 5000 so I now have a version B main board and expansion board, which I am attempting to install. After wiring the boards up the fan and all of the damers are working perfectly. The problem is that it is not kicking on the heat pump itself. I have been over the wiring diagrams repeated and checked the dip swithes and I can't find the problem. Obviously I am missing something. I would be grateful for any ideas.
Thanks
