I'm not familiar with the hydronic controls available, but Honeywell makes a T775 controller with a collection of output forms like relay, floating, and analog; as well as reset on certain models. Fairly flexible, yet simple to install, wire, and program.
I've used them for modulating SCR heat with reset, modulating heat & cool, staged cooling, and staged cooling with modulating heat.

The hardest part is figuring which T775 you need.
Very simple to program."If you can't explain it simply, you don't understand it well enough"
