11 Malfunctions and alerts

When the controller detects a malfunction, an alert symbol and alert code appear on the display. See the Info menu for more information about the alert. See also section Modbus registers , Alert registers.

Make a note of the alert in the service log to facilitate possible service actions. After the cause of the alert has been determined and corrected, you can delete the alert in the Heat pump menu, under Acknowledgement of alerts.

Try to resolve the situation yourself using the troubleshooting table first. If you cannot resolve the situation that way, contact an authorised technician.
