Checking operation
During normal operation, the alarm indicator lights green continuously to show that
everything is OK. When the alarm is triggered, it flashes green at the same time as a text
message is shown in the display.

Regularly check the alarm indicator to ensure that the installation is working correctly. It is
not always the case that you will notice a problem with the installation, for example, in the
event of a fault with the compressor the auxiliary heater starts automatically (operat
AUTO). For further information about alarms, see the "Troubleshooting" section.
