How can I reset the fault code displayed on the heat pump controller?

Resetting a fault code that appears on the Aerona³ Remote Heat Pump Controller can either happen automatically or it can be manually reset by a heating engineer. In most instances, once the fault is fixed and it returns to normal condition, the error code will automatically reset.

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 as follows:

Press – and + o buttons on the Remote Controller at the same time for three seconds,

OR

Press Reset SW on the Terminal PCB. Please refer to the image below.
