Radiant along with H/W baseboard

I ran in to a hybrid system. The kitchen zone is radiant heat controlled by a Tekmar 356 injection system and a Tekmar Heat only remote t-stat and Taco zone valve. The rest of the house is hot water baseboard controlled by individual Honeywell stats with 2 other Taco zone valves. The boiler has a domestic tankless coil. What I want to do is eliminate the coil and install an indirect along with outdoor reset. My dilemma is what would I use to interface the 356 radiant control and the baseboard controls to give outdoor reset to the entire system? The 356 has outdoor reset for the radiant zone only. Any information will be greatly appreciated. Thanks.
