Technical description: Inverter Error
What causes this fault?
This fault occurs when the heat pump’s brain is unable to send signals to the motor that drives the heating process. It is usually caused by a physical failure of the internal electrical circuits or a loose connection that prevents the system from regulating the power needed to run. In some cases, it can be triggered by a sudden electrical surge or moisture getting into the control casing.
