  Jason LucasAug 17, 2025
  If the Ferroli Furnace is showing an overtemperature protection activation, it could be due to several reasons. First, the heating sensor might be damaged; in this case, you should check its correct positioning and operation. Second, there might be no water circulation in the system, so you should check the circulating pump. Finally, air in the system can also cause this issue, so try venting the system.
