A used Viessmann Vitodens 100 compact heat only 24kW control panel/pcb part no. 7828495 taken from a working boiler type WB1A model no. 7179919. Please note that the plastic retainer on the 8 way socket has broken ( a common issue on these boards) but the connector still works correctly with the contacts undamaged. . See photographs. A boiler change to a different model from Viessmann means this part is not compatible and no longer required as a spare for me. Hopefully it will be of use to someone else as the colder weather approaches. Uk sale only Any questions please ask.
