Page 46: Sim Card
5.10 SIM card The main memory for the settings is in the flash memory of the integrated controller; the SIM card serves as a backup of all settings. When starting the integrated controller, the serial number of the SIM card is compared to that of the integrated controller. -
Page 47: Replacing The Integrated Controller Board And Using The Existing Sim Card
If an Integrated Controller without software is used, proceed as follows: 1. Switch off the power to the Nordmann Omega Pro and insert the USB stick with the requested soft- ware into the USB port at the back of the Integrated Controller. - Page 48 7. Open menu "Factory > Factory Default" and select <Reset Serial Number>, then confirm with <Yes>. 8. Disconnect the Nordmann Omega Pro from the mains and after 3 seconds switch it back on. Confirm the message "First Power Up" during the starting sequence with <Proceed>.
- Page 49 Transferring the original settings from the SIM card is not possible when: – A completely new control unit with a new serial number is delivered (see case 10.3). The serial number has been loaded into the integrated controller during production. It does not match the serial number of the existing SIM card.
