If you have UCM/Cbus1, you may be able to upgrade it to UCM/Cbus2 and take advantage of the powerful new features
The procedure is shown at http://www.comfortforums.com/forum11/3755.html
It included adding the U2 256 Bits EEPROM to the U2 socket. UCM/Cbus1 has been shipped out with an empty U2 socket for some time
However if your UCM/Cbus2 does not have the U2 socket, then you should NOT try to solder a socket. This is not easy as the ic pin holes are filled with solder. Trying to remove the solder with a normal soldering iron may damage the PCB tracks. This requires special tools at the factory.
If the U2 socket is not present you should order a new UCM/Cbus
You can upgrade the ucm/cbus firmware to UCM/cbus2 even without the U2 eeprom, but in the Status field, it will show \"EEPROM/Missing/Faulty\" instead of \"Normal/ No Error\" as shown below
