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.

What does the Al002 error mean on a Kermi x-change dynamic heat pump?

The Al002 error indicates that the second stage electric heater signals an overload condition. This can occur when the safety thermostat connection is missing or faulty. Check if the second stage heater is installed and configured correctly. If the safety thermostat has triggered, attempt a manual reset. Contact a qualified technician for persistent issues.

What does the Al050 error mean on a Kermi x-change dynamic heat pump?

The Al050 error indicates that the pressure differential between low and high pressure areas is too low. Heat the storage using auxiliary heating if possible. Perform a manual error reset. Contact a technician to verify compressor operation and refrigerant charge.

What does the Al048 error mean on a Kermi x-change dynamic heat pump?

The Al048 error indicates that the refrigerant circuit controller cannot establish connection to the heat pump controller. Perform a manual error reset. Verify the pLAN communication connection. Check the heat pump controller power and function.

What does Error 5 mean on a Kermi x-change fresh heat pump?

Error 5 indicates that the pressure switch has triggered for the first time. LED 3 shows red. The compressor shuts down but will attempt an automatic restart after 5 minutes. If the error recurs, contact a technician to check the refrigerant system pressure.

How loud is the Kermi x-flair heat pump radiator?

The fans operate very quietly at a noise level of only around 28.5 decibels, which is quieter than a whisper. The sound-optimised design includes decoupling features that minimise noise transmission.

Does Kermi offer remote diagnostics for heat pumps?

Yes, once connected to the internet, Kermi x-change heat pumps support remote maintenance and diagnostics. You can check your heat pump from a PC, tablet, or smartphone, and simple malfunctions or software updates can be handled remotely without requiring an on-site visit.

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.

How should I clean my Kermi shower enclosure?

After showering, rinse the inner surfaces with warm water, then cold water, and afterwards dry them. Use only mild, commercially available cleaning agents such as diluted vinegar water at a 1:1 mixing ratio. Avoid rough microfibre cloths and aggressive cleaning agents.

Can I replace radiators with Kermi underfloor heating?

Yes, but the heating surface must be large enough to achieve the required heating capacity. If space is limited, reducing the installation distance of pipes or installing panel heating in walls may help. The heating system may need adjustment for the lower temperatures used by underfloor heating.
