Outdoor reset

Any suggestions on controls for outdoor reset? Hot water boiler. I'm going to disconnect the tankless coil (Summer- Winter hookup) install an indirect with OD reset. Not sure whose control to use. Any guidance will be most appreciated.

    Tekmar 260. Argo dpm2 is pretty good too...or Depending on the set up of your boiler (pumps or Zv) you could do the Taco pc701 w/ the exp relay...

    SR50?-exp with pc700. Taco plugs right into your SR50? exp pump relay.

    Ken I would strongly recommend the Honeywell AQ251 from the AQ 2000 series I don't work for HW but I install this control a lot and really like it. It is very easy, read intuitive,to use will run up to 16 zones but comes as a one zone, a four zone and on up. Check it out I think you'll like it. Oh ya reasonably priced to boot.
