Hello again,

You will need a complete zone control panel, one built to be compatible with your air handlers and cooling system if you have AC, in order to accomplish the zone control with a boiler involved... there are many different configurations.

That is a simple relay, you need a bank of those with computer logic operating them, Taco makes a series that might work for you.

If you want engineering on that let me know, I will submit an additional service request.
