Re: Using CBUS Dimmer channel as normal switch
Ah OK,
Was looking for flexibility in using a dimmer channel rather a relay -
which
restricts my lighting options.
Does anyone have any practical experience with this on a CBUS dimming
channel. Again I only want the dimmer channel to fast ramp up on switch on,
and fast ramp off on switch off - well I think thats what it is called.
Cheers
