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.

    a few

    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.
