If the ARMED red LED  does not come on when armed to one of the modes (Away. Night, Day, Vacation), this could be due to having too many commands to C-Bus or EIB bus in the Away Mode, Night Mode, Day Mode Responses,
These messages may have caused the transmission buffer to overflow and lose the Keypad led command. We encountered this recently in the case of an installation with Comfort I where there were more than 10 Cbus commands in the Away Mode Responses. This can be fixed by splitting up the Cbus commands into two or more responses
eg

Response X: Cbus command, Cbus command, cbus command , ...., Do Response  Y after 1 second using Timer 1

Response Y: Cbus command, Cbus command, .. Do Response Z after 1 second using Timer 1

Response Z: Cbus commans etc

This is less likely to occur with Comfort II whuich has a larger buffer but nevertheless it is a good idea to split up the Cbus commands to around 8 at a time if you have many of them
