What it is
A wiring harness manufactured by Vaillant for the Modbus inverter fitted to Arotherm VWL 155/2 A 230V heat pumps. It carries the Modbus communication and power connections between the inverter and the appliance's control electronics. The harness is supplied as a single assembly with its factory-fitted connectors.
Signs this part needs replacing
- Modbus communication faults or loss of communication between the inverter and the appliance controls
- The inverter is not detected or does not respond during commissioning or diagnostics
- Visible damage to the harness: chafed insulation, heat-affected or discoloured conductors
- Loose, corroded or damaged connector terminals at either end of the harness
- Intermittent operation that changes when the harness or its connectors are moved
Before you order
- Confirm the appliance model and variant against the rating plate before ordering
- Check the existing harness routing and connector arrangement match this assembly
- Verify the fault is traced to the harness rather than the inverter or control board
- Check the harness length and connector count against the part being removed
