I had the same problem - Communications failure after upgrading SEM to 8.021. Using the programming cable I downgraded again to 7.207.
However I am now in a weird situation evertime comfort restarts it tells me communication failure SLAVE 1. When I log in via the keypad it will say communication failure restore and the error goes away. But next time Comfort is reset the same thing happens.
I Scan modules and see the slave there showing 7.207 firmware and zones on it work correctly.
I have tried a read modules (and then get told there is a mismatch and to scan again - which I do.
I then write selective (modules and settings) yet still when comfort restarts the error Communication failure
Please can you advise?
