The instructions supplied with ucmcbus seem difficult to understand, I am trying to have a comfort input control a cbus output, without success, I cannot understand what the problem could be, ucmcbus is receiving the command but the output does not operate, i have the group address set correctly and the application address appears correct, I have monitored the network and it appears that the key input toggles on and off but not the output, can anyone give me a basic overvue of how to get this working. Thanks Peakey.
