What does the Al039 error mean on a Kermi x-change dynamic heat pump?

The Al039 error indicates a phase error detected at the motor connection. This requires professional repair. Contact a qualified technician to verify electrical connections and motor wiring.

What does the Al038 error mean on a Kermi x-change dynamic heat pump?

The Al038 error indicates that the frequency converter drive has been deactivated. Check that all hydraulic valves are open, clean the water filter, and bleed air from the primary circuit. Verify the external contactor has 24V supply. Contact a technician if the issue persists.

What does the Al014 error mean on a Kermi x-change dynamic heat pump?

The Al014 error indicates that the general fault input reports an overload condition. When a high-pressure switch is connected, this error indicates similar issues to Al013. Follow the same troubleshooting steps and contact a qualified technician if needed.

What does the Al044 error mean on a Kermi x-change dynamic heat pump?

The Al044 error indicates Power Factor Correction circuit undervoltage. The electrical supply voltage is too low. Check the electrical supply. Perform a manual error reset. Contact a technician if the fault persists with adequate supply voltage.

Can Kermi x-net underfloor heating provide cooling as well?

Yes, the x-net system can provide cooling by circulating cold water through the floor. However, rooms with high humidity such as bathrooms and kitchens should be excluded from cooling operation to prevent condensation.

How does the Kermi x-net C15 thin layer system work?

The x-net C15 is an ultra-slim underfloor heating system designed for renovations. It can be laid directly on existing floor coverings without costly demolition, offering both heating and cooling options. The low installation height and quick reaction time make it ideal for retrofit projects.

How does dry cooling work with Kermi heat pump radiators?

Cold water from the reversed heat pump cycle flows through heat pump radiators with integrated fans. These extract room heat without condensation forming on the radiator surface. The x-flair radiators require thermostatic sensor heads with K settings for cooling operation.

What structural preparation is needed for heat pump installation?

Air-to-water systems need a stable outdoor substrate or ventilated basement space. Brine-to-water systems require extensive collector areas or authorisation for deep boreholes. Water-to-water systems demand two wells and groundwater permits.

How do I remove stubborn deposits from my shower enclosure?

For heavy limescale or mineral deposits that regular cleaning cannot remove, Kermi recommends using a specialist polishing paste. Apply to the affected areas and work gently with a soft cloth. Never use scouring pads, steel wool, or abrasive cleaners as these will damage the glass surface.
