KA 6 Hook up

My ka6 is on order since July so I'll still burn nut inside the house. My boiler is going to be installed in a brand new building 10x14 that is almost done. Already bought 2 heat exchangers and will run a closed loop system. Here is the question. Will I need to run thermostatic wire from the house to the boiler? I was thinking that the boiler should know enough to keep the water at 180 degrees. The circulation pump will run 24-7. I will use the controls on my propane boiler and just preheat the water returning to the propane boiler.Thanks Brian

Will this be a series hook-up? I too have a K6 on order since June 1. My plumber told me that he will run a thermostat wire from the coal boiler to one of my oil boiler zones with some kind of control. This will create a "dump zone" if my K6 gets to hot. Hope this helps.
