    Introduction The MB250 Controller is a device to manage stoves and boilers with automatic ignition and pellet loading. The operation of the heating system is determined by reading the exhaust temperature, water temperature, and through the acquisition of the parameters setup by the user. The parameters of the controller are fully configurable inside the menu.
