Possible Causes
Loose communication cable (e.g., Modbus/Canbus) between panels, Faulty interface module, Incorrect address or protocol settings, Electrical interference or grounding issues
How to Fix / Troubleshooting
Safety: Isolate power before opening control panels.
- Inspect communication wiring: Check the data cable between the Danstoker boiler controller and the burner control or remote I/O. Tighten terminals and ensure shielded cable is correctly grounded at one end only.
- Verify settings: On both devices, confirm that communication parameters (baud rate, parity, address) match the Danstoker documentation.
- Check power to modules: Ensure any communication interface modules are powered and status LEDs indicate normal operation.
- Test with short cable: If possible, temporarily connect with a short known-good cable to rule out cable damage.
If E15 persists, the interface or controller PCB may need replacement by a qualified technician.
