Compressor blocked symbol displayed — Compressor is not running

What does Compressor blocked symbol mean?

This symbol appearing on the display indicates that the heat pump's compressor is currently blocked from operating. This can be an intentional state based on settings or a protective measure due to an active alarm.

• The operating mode selected in menu 4.2 does not permit compressor operation.
• Compressor blocking is scheduled in menu 4.9.5.
• An active alarm is present, which is causing the compressor to be blocked as a protective measure.

Click steps to track your progress.

1. 1

   Navigate to menu 4.2 and check the selected operating mode, adjusting it if necessary to allow compressor function.

2. 2

   Review the settings in menu 4.9.5 for any scheduled compressor blocking and modify them as needed.

3. 3

   If there is an active alarm on the display, resolve that issue first, as it may be the cause of the compressor blocking.

4. 4

   If urgently needed, consider activating 'aid mode', but remember this only provides temporary heat/hot water and doesn't fix the compressor issue.
