Q: Is it possible to use cooling without activating the ventilation?

No, on the Eurom PAC 7.3 Compact , cooling requires air circulation. When you activate the cooling mode, the fan operates simultaneously with the compressor for two essential reasons: to expel heat through the external drainage pipe and to partially evaporate the condensed water extracted from the air. You can adjust the fan speed according to your needs: Low speed: 240 m³/h High speed: 280 m³/h However, you cannot stop the fan during cooling. It is an integrated system: without air circulation, heat would not be expelled from the unit and the condensed water would not evaporate properly, quickly filling the water tank. The PAC 7.3 Compact offers several alternatives according to your needs: the fan-only mode (circulating air without cooling) allows you to use the fan without activating the compressor. You also have a dehumidification mode and a sleep mode (which gradually increases the temperature after 1 to 2 hours of cooling) to adapt the operation to different situations. Cooling operates within an ambient temperature range of 16°C to 35°C. If the room temperature drops below what you have programmed, the unit will automatically stop cooling.

Q: What does error code E3 mean on the LO50?

The error code E3 is not an official error code of the Eurom LO50. According to the manufacturer's complete documentation, this device only has two error codes: E1 - Humidity sensor problem (reading error or malfunction) E2 - Pipe defrost sensor problem If your LO50 displays E3, several explanations are possible: Confusion with another code (E1 or E2 misread on the LCD screen) Failure of the display circuit or internal diagnostic system Malfunction of a sensor not documented in this model Dust accumulation on the sensors causing false signals Troubleshooting procedure: Completely turn off the LO50 (Power button) Unplug the device for 1 minute to reset the electronic system Plug it back in and turn it on - a reset often corrects these anomalies Clean the filter (at least monthly) and the intake/exhaust grilles Ensure that the device is level on its support (tilting affects the sensors) If E3 reappears, it indicates an internal malfunction of the diagnostic circuit or an electronic component In this case, contact an authorized repairer or Eurom directly (info@eurom.nl). Mention the undocumented code E3 - this may require specialized technical diagnosis or replacement of the electronic board.

Question 1

How to reduce the cold air flow for more comfort at the extremities using the PAC 7.3 Compact?

Accepted Answer

The PAC 7.3 Compact cools by circulating air: you cannot turn off the ventilation in cooling mode. However, you have several solutions to adjust comfort:

Reduce the fan speed - The manual offers two speeds: Low speed (240 m³/h) and High speed (280 m³/h). By selecting the low speed using the fan speed button on the panel or the remote control, you will significantly decrease the air flow and discomfort at your hands and feet.
Adjust the wind direction - The outlet blades are manual: by moving the handle left or right, you can redirect the air flow away from you rather than directly on the extremities.
Raise the required temperature slightly - A higher target temperature reduces the cooling output and decreases the feeling of intense cold.
Use Sleep mode - This mode gradually increases the temperature (+1°C after 1 hour, +2°C maximum after 2 hours), creating a softer and more gradual air circulation.

If the air flow is still uncomfortable even at low speed, consider positioning the unit in a different room or further away from your position.

No, on the Eurom PAC 7.3 Compact, cooling requires air circulation. When you activate the cooling mode, the fan operates simultaneously with the compressor for two essential reasons: to expel heat through the external drainage pipe and to partially evaporate the condensed water extracted from the air.

Question 3

What is the normal temperature difference between the incoming air and the air expelled by the AC3501 Wifi air conditioner?

Accepted Answer

To check the proper functioning of your Eurom AC3501 Wifi air conditioner, you should observe a temperature difference of at least 8 °C between the incoming air and the expelled air.

For example, if the room temperature is 28 °C, the air expelled by the air conditioner should be around 20 °C or lower. If you measure a difference of less than 8 °C, this may indicate a performance issue with your device.

To perform this test, use a reliable thermometer and measure the air temperature just before entering the air conditioner and that of the air coming directly out of the air conditioner, ensuring that the device is operating at high speed.

Question 4

What does error code E3 mean on the LO50?

Accepted Answer

The error code E3 is not an official error code of the Eurom LO50. According to the manufacturer's complete documentation, this device only has two error codes:

E1 - Humidity sensor problem (reading error or malfunction)
E2 - Pipe defrost sensor problem

If your LO50 displays E3, several explanations are possible:

Confusion with another code (E1 or E2 misread on the LCD screen)
Failure of the display circuit or internal diagnostic system
Malfunction of a sensor not documented in this model
Dust accumulation on the sensors causing false signals

Troubleshooting procedure:

Completely turn off the LO50 (Power button)
Unplug the device for 1 minute to reset the electronic system
Plug it back in and turn it on - a reset often corrects these anomalies
Clean the filter (at least monthly) and the intake/exhaust grilles
Ensure that the device is level on its support (tilting affects the sensors)
If E3 reappears, it indicates an internal malfunction of the diagnostic circuit or an electronic component

In this case, contact an authorized repairer or Eurom directly (info@eurom.nl). Mention the undocumented code E3 - this may require specialized technical diagnosis or replacement of the electronic board.
