So which wire do you use for the SPAL unit, heavy gauge or lighter gauge?
Are you using a SPAL temperature sensor?
The earlier SPAL units did not have the overcurrent protection, this is new with Version 3. I find it hard to believe that the MarkVIII fan pulls more than 30 Amps continously at 50-60% load, when the reported 100% load is 33 Amps
If Version 3 does not work, maybe you can use the brown wire to trigger a 70 Amp relay. Then the SPAL unit at least is still a temperature on/off controller...

I've wired it with both the positive wires - seemingly no difference in how it acts either way.
You could have the SPAL control a relay as you've mentioned, but if you are going to do that, I'd just get a temp switch or adjustable thermostat and remove/sell the SPAL controller. Leaving it in place makes for an awefully cumbersome and expensive temp switch.
It's the grey wire you'd want to use for that purpose - the brown wire is for a status output (to an LED).
