Lochinvar Knight with multiple heating zones

I'm currently in process with the install of a Lochinvar Knight WHN-110 with three heating zones (with circulators) and a DHW zone. One of the heating zones is a hydronic coil in our air handler (first floor), one is Warmboard radiant (part of first floor), and the other is baseboard (basement). We had initially purchased a Taco SR504-4 to control the different zones thinking that we'd utilize a single temp for the heating zones. We'd have a thermostatic valve for Warmboard to reduce the temp for that zone.

But now we're thinking that it would be best to utilize multiple temps here as Lochinvar supports it, but there's a bit of confusion around the setup for multiple temperatures via the boiler. Given what we currently have, is it possible to configure multiple temps? Or do we need to without Lochinvar's Multi Temp Loop Control or some other controller?

Thanks!
