Hellooo,
I had to relocate a small 750 Watt convector wall heater yesterday in a new house. It is of French manufacture but I have forgotten the make. The integral flex had three cores, a brown L, a blue N and a black pilot wire. The installation electrician had sleeved the black bare copper end with green/yellow sleeving which threw me a bit as the appliance is double insulated and displays the square within a square symbol. An instruction book was not available. So just what does the “pilot wire” do?
Thanks,
Z.
