New Crown Freeport with Megastor Tank. The aquastat on the megastor, how do I get it to the Exp 506 Relay or am I going about it wrong and it goes to the boiler control. Any help for this newbie appreciated.

    aquastat on indirect to tt on priority zone (if usuing priority). If using a argo box or Tac controller like sr50#, then no add transformer needed.

    Thanks Joe I thought I had it figured out but the 110V wiring business on the aquastat instructions had me confused. I keep thinking like the old boiler with the tankless coil which had to be hot all the time. I'll get this cold start figured out yet.
