What does the Al028 error mean on a Kermi x-change dynamic heat pump?

The Al028 error indicates that the minimum drive temperature has fallen below the threshold. This typically occurs at very low outdoor temperatures or after extended power outages in cold weather. Heat the storage using auxiliary heating if possible. Perform a manual reset once conditions improve.

What does Error 3 mean on a Kermi x-change fresh heat pump?

Error 3 indicates that the temperature sensor on the evaporator is short-circuited. LED 3 shows red and the compressor will shut down. Contact a qualified technician to inspect and replace the evaporator temperature sensor.

What does the Al053 error mean on a Kermi x-change dynamic heat pump?

The Al053 error indicates that the defrosting duration limit has been exceeded. If safe to do so, gently remove ice accumulation from the outdoor unit. Use auxiliary heating if temperatures are very low. Perform a manual error reset. Contact a technician to review defrost settings.

What does the Al020 error mean on a Kermi x-change dynamic heat pump?

The Al020 error indicates that the minimum allowable suction temperature threshold has been exceeded. If ice is visible on the evaporator, carefully remove it. Perform a manual error reset. Contact a technician to inspect the refrigerant levels and sensor calibration.

What does the Al004 error mean on a Kermi x-change dynamic heat pump?

The Al004 error indicates a fan overload condition. This may be caused by power supply issues, winding short circuit, or impeller blockage. Check for obstructions blocking the fan and remove debris if accessible. Perform a manual error reset. Contact a qualified technician if the error persists.

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 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.

What should I consider when replacing a bathroom radiator?

The required heat output must match the radiator size, and the connections must be compatible with your existing pipework. Purely electric radiators offer a good alternative for localised heating requirements as they only need a socket connection.

Can I replace a standard radiator with an x-flair heat pump radiator myself?

The physical replacement is straightforward as lug positions are identical to standard radiators, allowing existing brackets to be reused in most cases. However, the x-flair requires an electrical connection for its integrated fans, which should be installed by a qualified electrician.
