What does the Al055 error mean on a Kermi x-change dynamic heat pump?

The Al055 error indicates that the circulation pump's fault signal indicates an overload condition. Check that all hydraulic valves are open. Clean the water filter. Ensure adequate cooling air supply to the pump. Perform a manual error reset.

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 Al012 error mean on a Kermi x-change dynamic heat pump?

The Al012 error indicates that the heat source temperature (EQ temperature) is too low. Check for and remove any airflow obstructions around the outdoor unit. Perform a manual error reset. Contact a qualified technician to verify refrigerant quantity and expansion valve settings.

What does the Al001 error mean on a Kermi x-change dynamic heat pump?

The Al001 error indicates a general error at the frequency converter (Power+ LED flashes red). This can occur due to communication issues between the frequency converter and refrigeration circuit controller. Perform a manual error reset, verify voltage and phase sequence, and check the compressor current draw. If the issue persists, contact a qualified heat pump technician.

Why does silicone need to dry completely before showering?

Silicone is very sensitive to water while drying. Moisture during this time reduces the adhesive quality and can make the seam leak. Apart from sealing, silicone also provides structural stability to the shower enclosure. All work on the enclosure should be avoided during the 24-hour drying period.

How do I find a Kermi specialist installer?

Use Kermi's specialist partner search tool to locate qualified installers in your area. Authorised specialist partners provide professional advice, careful planning, and expert installation.

Can heat pumps work in older buildings?

Yes, heat pumps are viable for older buildings as they use free environmental energy, reducing dependence on fossil fuels. Adequate insulation and compatible radiators are important to ensure efficient operation at lower temperatures.

What is a radiation shield and should I use one?

A radiation shield is installed behind the radiator to prevent heat energy from being lost to cold external walls. With a Kermi radiation shield, up to 80% of heat loss to the wall can be avoided.

What are Kermi convectors used for?

Kermi convectors are ideal for rooms with large glass areas such as panorama windows, bay windows, or conservatories. With their high heat output in a low-profile design, they form an invisible heat protection shield and prevent cold air from spreading through the room.
