Danfoss – 35VUBMA102
6 Regular checks
6.1 Checking operation
During normal operation, the alarm indicator lights green continuously to show that every-
thing is OK. When the alarm is triggered, it flashes green at the same time as a text message
is shown in the display.
Figure 18: Flashing alarm indicator in the event of an alarm.
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 (operating mode
AUTO). For further information about alarms, see the ”Troubleshooting” section.
