Thanks for the reply.
I did some testing and this is really getting weird.
First - the controlled devices/scenes work, they turn on or off as per the button pressed.
There are 2 sequences of flashing I noticed:
1. A delay of about 5 seconds, then one flash, delay of 2 seconds and 14 or 15 flashes.
2. A delay of about 5 seconds then 20 flashes.
On one RL the On and Off clicks of button 3 produce the different flash codes.
This RL has the 20 flashes for B3 off, B6 on and off and the 1-15 flash on B1 on and B3 on.
The other RL has the 20 flash for B3 on and off, B6 on and off and B5 on.
One time I did notice the 1-15 flash for B3 off, but since then it has been 20 flashes.
I gather from the lack of responses that there is no users or developers guide anywhere that lists what the flashes mean?
Thanks again...
