It would be better to wire the control kit to the primary control than to the aquastat relay. The main reason for this would be to bring the power venter on when the primary control is calling. If you wire the control kit to the aquastat relay and the primary control trips out, the power venter will keep running anytime the aquastat relay is giving the control kit a call for heat. This could result in premature power venter motor failure and an irate customer.
