Tekmar RoomResponse or Outdoor Reset Modulation
I am looking for some insight on the best way to set up my heating system, specificallyhow to modulate my boiler. I realize that there are many variables and no definitive answers but I was hoping to get some professional opinions. My question is, should I use the Tekmar 306P to modulate my Laars Mascot LX boiler using their RoomResponse technology, or should I let the boiler modulate itself using the outdoor reset?
