Scross, the shower heads probably can't all work at the same time.
A bit like a typical shower and the bathtub faucet, it's one or the other, not both.
There are four separate controls for six heads, so some are shared, obviously, but I don't know that they are flow-limited or switched. I haven't seen an operations manual for it yet, though, so I may be wrong.
