I have a new clock module for a customer that is programmed up ready to go except the RND button doesnt seem to be working ? If i follow any of the instructions on how to inititiate random stuff - hold channel & RND or d+ h+ m+ channel RND - it never appears. Am i missing something - is RND disabled by default ? I've reset the unit a couple of times but still no joy... Any suggestions appreciated - perhaps its a faulty one - though i not a faulty CBus unit yet :D Dean.
