I've run into a problem where I can't seem to activate an RRD-6D dimmer into my system. This dimmer was used previously at my house, but I replaced it a few months ago with a 6CL to dim some LEDs in my kitchen. Now I want to re-use the RRD-6D in the dining room, and when I go to activate, it says "this device is already activated" but continues to ask me to press the dimmer pad to activate this dimmer. It never works. This is the only device that won't activate or transfer, the rest of the system works fine.
It is possible that because this dimmer was used previously, it is still "activated" somehow, and I need to restore it to factory conditions before it will work in its new location? If so, how do I do that? Or if this is not the case, what could the issue be?
