Electronic pellet burner controller – NPBC-V3C-1/ NPBC-V4C-1/ NPBC-V4E-1
Change code
– Enable/Disable the access code for the Factory Settings. The code could be any up to
6-digit combination. It is not necessary to use all of the digits. Changing only one of them is a valid
code. Use only the numbers from 0 to 9. Only the currently editable digit is visible. Use the up and
down navigation buttons to set the current digit and switch to the next/previous position with the
right/left navigation button. To enable the code, check the check box, enter the code and then repeat it.
If you use less than 6 digits, make sure to leave the same ones when you repeat the code. If it is
correctly set, the next access to the Factory Settings will require access code.
Output test
– This menu directly controls all of the controller's outputs for test purposes only when
the burner is in Standby mode. Test the main and the exhaust fans' speed by increasing their power
from the parameters FM and FSG. Test the rest of the outputs by activating them with a check sign on
the corresponding check box. The controller supplies power to the outputs for 5 minutes, if no buttons
are pressed during that time.
