Need Tek Mar help

I had a job just land in my lap where I have to straighten out a homeowner installed radiant floor problem. I need a variable circ control for injection with boiler return water control to keep return above 130, (cast iron Burnham). I have a Tekmar 356 sitting on my desk but the boiler sensor in the Aplication diagram has the boiler sensor on the supply. Do I need another controller or can the 356 work for my app. Thanks for your help in advance.

    optional return sensor

    looks like you just need the (optional boiler return) sensor

    Thanks guys

    I finally got to the literature I needed.(D356) The boiler sensor can go on the Supply or the Return. All systems go.
