Electronic pellet burner controller – NPBC-V3C-2 / NPBC-V4C-2
Additional information about the controller
After the power supply to the controller is on, a yellow text with Control module's version appears
on the screen for 2 seconds. There are two options for this text: NRC-6 MV – a control module for
pellet burner or NRC-6 SV – a control module for pellet burner with an option to work as a room
thermostat. After that the controller displays a screen with its version and the software versions of
the Control module and the Executive module:
The controller should display its main screen within 3 seconds. If this doesn't happen and the
Executive module's version is missing, there is a communication problem between the modules or
the Executive module is not working. To locate the problem, check the Executive module's green
LED. Normally, it should blink on 0.5 seconds. If this is the case, the problem might be in the
connection between the modules. If the LED is blinking on 2.4 seconds, there is no software in the
Executive module. Use the remote monitoring and control program to upload the software in the
module.
If the controller's version is in red, there is a hardware incompatibility between the modules.
If the software version of the Executive module is in red, there is a software incompatibility
between the modules.
