5 fault codes documented
Alarm bell icon on display — Malfunction detected
This icon, appearing with a red status lamp, signifies a malfunction that the system cannot resolve automatically. The display will show the type of alarm and offer potential solutions.
Low hot water temperature or no hot water — Potential causes identified
If you experience insufficient hot water, several factors could be the cause, ranging from simple valve settings to operational modes.
No display message, but system not operating correctly — Basic checks needed
If the system is not functioning as expected but no specific error code or message appears on the display, several basic checks should be performed.
Red status lamp solid — Malfunction occurred
The status lamp changing from green to red indicates a malfunction. An alarm icon will also appear on the display. This means the system cannot fix the problem on its own.
Red status lamp blinking — Potential communication issue with heat pump
While not explicitly defined as blinking, a red status lamp indicates a malfunction. Intermittent red light could suggest a communication problem between the control module and the heat pump.
