What to do if my IVT Airbox E 50- 90 shows DHW temperature sensor alarm TW1 error?
- A
  Anthony TuckerAug 7, 2025
  If your IVT Heat Pump displays a DHW temperature sensor alarm TW1 error, there are several potential solutions: * If no DHW system is installed, deactivate the DHW system in the service menu. * If the sensor is defective, replace it. * If screws or plugs are loose, tighten them. * If the sensor values are incorrect, replace the sensor. * If the sensor values are correct but the voltage is incorrect, replace the user interface.
