In the event of an alarm, some type malfunction has occurred, which is indicated by the status lamp shining with steady red light. A dialogue box appears in the display, containing information about the alarm.

ALARM
In the event of an alarm with a red status lamp, a malfunction has occurred. The display shows what type of alarm is and lets you reset the alarm.
In many cases, it is sucient to select "Reset alarm" for the installation to revert to normal operation.

If the alarm indication disappears after
you have selected "Reset alarm", the alarm has been remedied. If the alarm recurs, the cause of the problem remains.
"Auxiliary operation" is a type of emergency mode. This means that the installation attempts to produce heat and/or hot water, even though there is some kind of problem. This could mean that the heat pump's compressor is not in operation. In this case, any electric additional heat produces heat and/or hot water.

Caution
To select "Auxiliary operation", an alarm action must be selected in menu 7.1.8.1 - "Alarm actions" in the main product.

Caution
Selecting "Auxiliary operation" is not the same as correcting the problem that caused the alarm. The status lamp will therefore remain red.
