Had this with a divertor valve on a Main combi, took GC number away with me to order the part and merchants came up with 3 different divertors! Rang tech support and they said they had three different variants during production and the only way they could tell me which one I needed was to be be stood in front of boiler and describe it to them! Could be a similar thing with your PCB

upgraded pcb,you need the full serial number to get the correct one

The difference is not really noticeable. But there's different boards for different serial numbers. Before and after a certain date which is identifiable by the date read from the serial number first 4 digits. So for example a 28kw duo tec built in the 20 week of 2009 will be CAC0920XXXXXXX

The difference is mainly due to the diverter valve, the old black diverter valve head is a more powerful motor than the white and black.

Either way the new pcbs both are vastly improved and come with brighter displays.
