I'm looking for some help on setting up area addressing to act as master On/Off. I have created 4 Zones controlling relays only. It is my understanding that all channels on the relay with the appropriate area address can be controlled by a key input with the same area address, therefore zoned light groups need to be allocated to the appropriate relays. I'm using a 4 gang key switch to control the 4 zones. Can anyone step me through the process to achieving individual zone master On/Off control. Regards
