2 circulators, one Thermostat

Rubline

Senerio:
5 zones, 1 main circulator. I need to have an additional inline circulator that is connected to my radiant heat circuit to come on when the radiant thermostat calls for heat. When the plumber installed the radiant, he screw up the pipe layout so I need an additional circulator to run along with the single main circulator. Taco 007. Right now the Taco runs continuous because it is plugged into an outlet and pumps against a dead head until the zone valve opens.

Thanks in advance.
