(without separate coding), but no SEC board can be
detected on it
If it concerns the SEC configuration,
test the ModBus cable between the
HeatingIO and SEC board. Also check the
SEC board to see whether everything is
flashing as it should
If it is NOT a configuration with SEC
board (e.g., because it concerns a P184
unit), check the coding resistor of the
HeatingIO
792
LIN-connection lost Unable to find a master board or any configuration Check the coding connector on the LIN
board(s)
793

„Case 1 - Inspect inverter.
Remedy fault
Case 2 - Inspect HW throughow, overow,
ow temperature sensor and high-
pressure sensor.
Remedy fault.”
