two zone circulator electrical connections taco to becket afg

would attaching the two taco's to c1 and c2 on the aquastat and the two thermostat wires to the tt work. Or do i need to use a taco relay board with 2 or 3 zones? Anyone know?

sure it will work. when you turn either thermostat up, both circulators will run. I assume though that that is not your intent so, yes you will need another relay to call the 2nd zone. You can go with a Taco relay or a honeywell 89a or 854 or one of the newer electronci versions. Either way you need to isolate the thermostats and circulators from each other.
