Hi All Newbie here so please be gentle! Have a problem with an 8 ch dimmer. I have a total of 4 units which have been working perfectly. The system itself is working well and I am delighted with it. However, when the renos were done, there were a number of spare channels for future expansion. I now wish to use one of the spares however, it seems to have defaulted to high and now matter what I do the until won't switch the channel off. (number 3) I have tested the second spare (channel 6) and I have the same problem but all others work well. I have re-set the unit, tried toggling, checked all parameters I could think of on the Toolkit all without sucess. The only strange thing is that the power light on the unit is flashing. So basically, HELP!!!!! Thanks for any assistance. Cheers Adrian
