What it is

The Vaillant 0020269448 is an inverter module used in Arotherm air-to-water heat pump outdoor units. It controls the speed of the compressor drive, matching output to the heating demand of the system. It is a service component for the Arotherm 5/5 range.

Signs this part needs replacing

  • The outdoor unit fails to start, with the compressor not running
  • The heat pump trips or shuts down shortly after start-up
  • Fault codes relating to the inverter or compressor drive appear on the controls
  • Intermittent operation, with the unit cutting out under load
  • Reduced or lost heating and hot water output despite a call for heat

Before you order

  • Confirm the appliance model and variant from the data plate on the outdoor unit
  • Check the existing part number against the manufacturer's parts list for your unit
  • Verify the unit is one of the Arotherm 5/5 AS 230V S2 models listed in the Fits section
  • Inverter work involves mains voltages and refrigerant-side equipment — fitting should be carried out by a competent heating engineer
