Looking for help on programming boiler heating circuit. B2ha boiler with indrect with low loss header, radiant floor one room with vitrotrol 200a. No mixing valve. Trying to have the room temperature sensor built into the 200a adjust the curve, and shut off the pumps if the heat gain is achieved with fire place in the room. Pump for low loss header and IDWH are separate and floor pump wired into 28 option. Three pumps total. Any older manuals explains the viessman program functions in more dumb downed level. Love all the option but still learning. I am one used to the buderus system and am a firm believer of constant circulation. Thanks for any input.
