Hi Gandalf / Gael

I had another go. This time the sockets on the left are working! have made some progress. It appears that on my powerbar the connections looking from left to right are 6, 5, 4, 3, 2, 1 and not 1, 2, 3, 4, 5 and 6.

The heaters are now on! I shall update later when I have had chance to check the temperature is being controlled OK.

GHL should really publish a pdf showing all of this!
