This component is critical for proper refrigerant circuit operation.

What does the 203 error mean on an Immergas heat pump?

The 203 error on an Immergas heat pump indicates a communication error between the inverter and main control board lasting more than six minutes.

This fault may require inverter board inspection or replacement.

What does the 202 error mean on an Immergas heat pump?

The 202 error on an Immergas heat pump indicates a sustained communication error between the control kit and outdoor unit lasting more than three minutes. Switch off the heat pump at the isolator switch for five minutes. Switch back on and monitor for the error. If communication is not restored, contact a qualified technician. Do not repeatedly reset the unit as this will not resolve a wiring or component fault.

What does the 24 error mean on an Immergas boiler?

The 24 error on an Immergas boiler indicates a push button control panel anomaly. The main circuit board has detected a fault with the user control panel. Switch off the boiler at the electrical supply. Wait 30 seconds and switch back on to reset.

What does the 441 error mean on an Immergas heat pump?

The 441 error on an Immergas heat pump indicates cooling operation has stopped because the outdoor temperature has fallen below 9 degrees Celsius. This is normal protective behaviour, not a fault. The heat pump will automatically resume cooling operation when outdoor temperatures rise to within normal operating range. No action is required. The unit should resume normal operation as conditions change.

What COP (efficiency) can I expect from my Immergas heat pump?

The Coefficient of Performance varies by model and operating conditions. For example, the Audax Top 6 ErP achieves approximately 4.28 COP when producing water at 35°C, meaning it delivers about 4.28 kW of heat for every 1 kW of electricity consumed.

What annual maintenance does my Immergas boiler require?

Annual maintenance should include cleaning the heat exchanger on the fume side, cleaning the main burner, verifying correct ignition and operation, and checking burner settings for both heating and hot water phases. A visual inspection for leaks and corrosion is also required.

What do the symbols on my Immergas boiler display mean?

During normal operation, the display shows a green illumination with symbols indicating boiler status. The display typically shows the current water temperature. A flame symbol indicates the burner is active. A tap symbol relates to domestic hot water functions. A radiator symbol relates to central heating. Error codes appear as numbers or letter-number combinations when faults occur. When on standby, a horizontal segment appears. Consult your specific model manual for detailed symbol meanings as they can vary between models.

How should I protect my Immergas heat pump outdoor unit during winter?

Maintain a clear space of at least 60 centimetres around the outdoor unit at all times. After snowfall, gently brush away any snow accumulation from around the unit using a soft broom. Never use sharp objects to remove ice or snow as this can damage the coil fins. Do not cover the unit or stack anything on top of it as this restricts airflow. Some frost on the unit is normal and the automatic defrost cycle will handle this. If the unit remains frozen for more than a few hours, contact a qualified technician.

What should I do if I smell gas near my Immergas boiler?

If you smell gas, do not operate any electrical switches, lights, or the boiler controls. Do not use any naked flames or electronic devices. Open windows and doors to ventilate the area only if it is safe to do so. Do not attempt to locate the source of the leak. Leave the property immediately and take all occupants with you. Once safely outside, call the gas emergency service. Do not re-enter the property until it has been checked and declared safe by a Gas Safe registered engineer.
