Electronic pellet burner controller – NPBC-V3C-1/ NPBC-V4C-1/ NPBC-V4E-1
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.
