Didnt manage to get an email to Rich Bell - or a response from the HES community forum or Light Network.....

However, between Ian N and Hugh, we figured out that the fan speed setting was in an OLD fixture software version, and is not in the current latest version (1.5.0) so fan speed control on a DL1 is no longer possible.

This has also been a sad example of the lack of technical support from HES in the UK. I tried phoning the main number and just got an answerphone - also tried a few mobiles of certain HES staff - and none of those were answered either (I think one has changed recently too...H?) So it seems that if we have issues with HES kit - we have to sort it out ourselves (except catalyst) or ask those among us who used to work for FP/HES who have now re-located to other companies.

This is obviously not related to Catalyst Software (which has a great tech support forum ) - but theres enough people who read this forum that might agree and may be able to pass the message on....
