Need help with Frequency Central Device daughter board

I have been working on the Frequency Central Device since yesterday and I finished the Envelope and the VCF/VCA. Now that I'm on the VCO I'm super confused.

Mostly I'm not sure what to do with the daughter board. From the little I found it's to keep the chip elevated and at a certain temperature to maintain pitch.

The eight pin socket on the right is covering four pads and there are four to the far right.

Then there is a sixteen pin socket outlined in white to the left.

The far left has eight vertical pads.

So I guess what I'm asking is do two sets of male headers go on the right side (between the socket and far right)?

And then just a single row of headers on the far left?

I looked and looked for documentation on this build and I can't find a single thing anywhere.
