  back to top

you upgraded the UCM/CBUS1 to UCM/CBUS2

UCM/CBUs1 does not have an EEPROM in U2
UCM/CBus2 requires an EEPROM in U2

The old Cbus SIM Module may also not be compatible with UCM/CBus
see the 2nd topoc here http://www.comfortforums.com/forum11/3755.html regarding upgrading UCM/Cbus1 This shows the old SIM Module which is not compatible

You need a new SIM Module and a U2 EEPROM 24C256

Take a photo of the UCM/CBus that you have
