Multiple GB142 wiring?

in THE MAIN WALL
has anybody done a 2 GB installation(both boilers used for domestic production)? If so, how are they wired? The application guide has the piping diagram, but no schematic. I have been kicking a few ideas around in my head & just wanted to hear if anyone had accomplished what I am trying to do. I will be zoning w/ circs (5 zones of fin tube baseboard & cast iron radiators), using an Argo relay, no room sensor, indirect temp & priority via BC10 boiler controls. I want to keep them modulating, so I was thinking I wouldn't bring the Argo box back to the TT's on the boilers. My problem is getting the boiler loop circs to turn on when I get a call for heat & a zone pump turns on. I thought maybe I could go from ZC on the Argo to 63 on the heating pump terminals of the boilers to get the boiler pumps to come on when any of the zoning circs get called on. I figured the boilers would ramp up & down based on return temperature. All I'd really be doing is turning on the boiler pumps. Sound ok? Has anyone done this? Please advise.

    wiring on the GB142

    Your manifold pump which is included; should have been wired to the 61,63 terminals. The Argo board can also be wired to the 63 terminal as long as you will not exceed 5 amps. I would suggest wiring this to the same boiler that you will be using for domestic.
