exqlode Posted February 11, 2023 Report Share Posted February 11, 2023 Heyhey, maybe someone can help me I bought a used sundance sentry 850 here in germany. Today i tried to to check the electronic, but nothing worked. Sometimes if i turn the power on the Display shows 0000 and you can hear the blower working slowly, sometimes the Display shows - - - - and you cant hear anything. I added three pictures. Is the jumper setting correct? What do the jumper settings mean, I have no plan for the jumper. Maybe someone has an idea Thank you Quote Link to comment Share on other sites More sharing options...
