Electric Boiler Controller NELBC-1
Service Settings
The service settings parameters should be modified with high attention. The controller provides the
option to restrict the access to these screens. If this option is activated then before displaying
Service settings menu the following screen requires entering the access code first:
When access code is entered by the virtual keypad then the last digit is displayed for 2 seconds,
after which it is replaced by "*" symbol for security reasons. When the code is entered then button
should be pressed for confirmation. If the entered code is correct then Service Settings menu is
displayed. Otherwise, the corresponding message is displayed after which it is only possible to
return to the main screen. If no code is entered then the controller returns to main screen too.
The "Service Settings" screen is as follows:
During the first 20 seconds after the power supply is switched on the controller checks for the
connected temperature sensors for the heating and the hot water section of the boiler. If all the
sensors needed for the corresponding section are disconnected then the controller considers this
section is not available and changes the operation mode if needed. Until the startup self-test is
completed "Heating Setup", "Hot Water Setup" and "Screed Drying Program" are not
displayed in Service Setting menu. These lines appear only if the self-test finds the corresponding
section of the boiler as available.
