As C4 don't support the unit any more and the PUS15 commonly fail we offer a replacement board .
It takes about 30-45 to replace it and it is not a direct fit I.E. you will use only one out of the 4 corners screws and the 4 wires will have to be exposed and screws into the connectors on the board (not cilices in)
we have it for the last 2-3 years and works better than the original may found in eBay
