You may not know but you can use LIGHT commands to control lights in the current room, and you can use LINK LIGHT to control lights in all the rooms where a 2-way B&O device is.
When you press LINK LIGHT, the BM7000 gets the signal and transmit it through the MCL network. All the other TVs and IR eyes on the network will re-emit the signal in other rooms.
This is of course not used in modern Masterlink, 1 way devices :-(
What you need to know is that in fact you have 18 light pictures in the memory of a LC2: LIGHT 1 to LIGHT 9 and LINK LIGHT 1 to LINK LIGHT 9 as Global (=LINK) light pictures.
When programming the BM7000 to start Light picture at a certain time, it sends a Global command, a LINK LIGHT 1 in fact.
So what you need to do is memorise the light picture you want to program as a LINK LIGHT 1 light picture.
