Grundfos pump Plan wiring centre fault boiler on constant demand. Heating Engineer informs me that it is a fault in wiring centre which is no longer available from Grundfos

Boiler is Evo HE without pump overrun is constantly on demand fires up until it over heats

Any ideas where to purchase Wiring centre

I understand that you can only purchase complete pump plan kit part number 59525647 includes twin pumps and wiring centre
