Bill,
I am going to take the 120 VAc that would normally come from the board to the compressors, and trigger the contactors with that. It's a bit of extra, but simple wiring. So it will take the 15 amp compressor current completely off the board. In the past others have had either compressor relays or the compressor supply circuits fail on the boards. The fans don't draw much current so I won't fool with them.
One could pull the 12v signal on the board to trigger a contactor, but that seems like a lot of extra monkeying around.
I will put the contactors in an external electrical box just outside the SCS unit. It doesn't make sense to cram them into the space with the board.
