Can I reset the fault code displayed on the heat pump controller?

If a fault code appears on the screen of your Aerona³ Remote Heat Pump Controller, in most instances, once the fault is fixed and it returns to normal condition, the error code will automatically reset and it will no longer display on the remote controller.

However, if the fault has resulted in the heat pump stopping, it may not be possible to reset the fault code automatically and in these cases, it will need to be reset manually by a heating engineer. You will therefore need to contact your heat pump installer or service engineer for further support.

If your remote controller is showing a fault code, here are some useful links to other helpful resources:
