It is very common for manufacturers to keep this information "proprietary",same as automotives.All the major pellet stove manufacturers and suppliers are the same,over here.Not a new thing at all,but,in my opinion,not a right thing.On automotive vehicles,it created so many problems,for the repair industry,federal laws were introduced to allow opening the programming up,and,in most of the world that also happened.I do not expect to see this ever happening in the pellet stove industry,as it is so small.Good luck with your project,and please keep us informed.
