The Fan 50 Plus pins control board provides backward compatibility with earlier Fan 50 Plus and UIB furnace control boards whilst adding modern functionality to classic RV heating systems. If three spark ignition attempts fail to detect flame, the board powers down the fan motor, protecting against battery drain and eliminating cold-air circulation.
