Refrigeration equipment of the brand Paracelsus is deservedly popular due to its reliability and ability to maintain a stable microclimate even in hot summers or chilly winters. Correct temperature setting is the foundation for long-term preservation of products and uninterrupted operation of the compressor. Many owners encounter difficulties during the initial setup, not knowing how to interpret the display readings or adjust the freezing power.
In this article we will analyze in detail the algorithm of actions for various models, including the popular series KH and PH. You'll learn how to avoid common mistakes that can lead to food spoilage or increased energy consumption. Proper calibration of the thermostat extends the service life of the unit.
Before you start manipulating the control panel, it is important to understand the basic principles of operation of your device. Temperature conditions inside the chambers directly depends on external conditions and frequency of opening doors. If you have just installed the refrigerator or defrosted it, the adjustment should be made after the chambers have completely cooled.
Design of the control panel and interface
The refrigerator control interface Paracelsus can vary significantly depending on the year of manufacture and the specific series. Most modern models use a digital display located on the outside of the door or inside the refrigerator compartment. Older modifications may be equipped with a mechanical thermostat with a rotary knob.
Digital models usually have separate indicators for the refrigerator and freezer compartments. Clicking the corresponding button allows you to switch between setting modes. The screen displays the current set temperature, and blinking of the indicator indicates the possibility of changing it.
It is important to distinguish indication modes: constant light means normal operation, and blinking often indicates the process of changing settings or an emergency situation. In some models, such as Paracelsus KX 0.7, control is carried out through a hidden panel, which is activated by touch.
⚠️ Attention: If the display does not light up after turning on the power, check the electrical connection. In some models with an energy-saving mode, the screen may go dark after a certain period of inactivity.
For precise settings, you need to know the button labels. The snowflake button usually represents the freezer compartment, and the thermometer or drop symbol represents the refrigerator compartment. Holding the button for a long time often turns on additional functions, such as “Super Freeze”.
Step-by-step temperature adjustment in the refrigerator compartment
The optimal temperature in the main compartment should be in the range from +2 to +5 degrees Celsius. It is under these conditions that most products retain their freshness for the longest possible time, and bacteria multiply the slowest. To set the desired value, follow these steps:
- 🔹 Press the mode selection button for the refrigerator compartment (usually indicated by "Fridge" or a thermometer symbol).
- 🔹 Use the "+" and "-" buttons or the multifunction knob to change the readings on the display.
- 🔹 Wait until the end timer (usually 3-5 seconds), after which the new values will be saved in the controller’s memory.
- 🔹 Check if the indicator has stopped flashing, which will confirm the successful acceptance of the settings.
If your model is equipped with electronic control, changing the parameters occurs instantly, but the compressor will start working in the new mode only after a few minutes. This is a protective mechanism that prevents frequent cycles of turning the engine on and off.
In models with a mechanical regulator located inside the chamber, adjustment is made by turning the handle. The numbers on a scale from 1 to 5 or 1 to 7 do not indicate degrees, but indicate the intensity of cooling: the higher the number, the colder. To set +4°C, position 2 or 3 is usually sufficient.
☑️ Checking the settings of the refrigerator compartment
Adjusting the freezing mode in the freezer compartment
The freezer requires lower temperatures to ensure deep freezing and long-term storage of meat, fish and semi-finished products. The standard value is -18°C. However, to quickly freeze fresh food, you can use the “Super Freeze” mode, which temporarily lowers the temperature to -24°C.
To activate this mode, press the corresponding button (often with a snowflake icon or the words “Super Freeze”). The indicator will start flashing, indicating that it is operating in enhanced mode. After a certain time (usually from 8 to 48 hours, depending on the model), the refrigerator will automatically return to standard settings.
It is not recommended to keep the “Super Freeze” mode on all the time. This leads to Excessive energy consumption and accelerated wear of the compressor. Use this function only when loading a large volume of fresh food.
In some industrial and semi-industrial models Paracelsus freezer and refrigerator settings may be independent or linked. If you have a two-compressor system, you can set the parameters for each circuit separately without affecting each other.
What is fast freezing and why is it needed?
Fast freezing prevents the formation of large ice crystals inside the cells of products. This preserves the structure, taste and beneficial properties of meat or vegetables after defrosting. Conventional freezing is slower, forming large ice chips that can damage the tissue of the product.
Table of recommended temperatures for storing food
The correct distribution of food on the shelves of the refrigerator directly depends on the set temperature. The microclimate may differ in different areas of the chamber, even if the sensor shows an average value. Below is a table that will help you optimize storage.
| Product type | Recommended temperature | Shelf life (approx.) | Placement area |
|---|---|---|---|
| Fresh meat and fish | 0...+2°C | 1-2 days | Lower shelf (freshness zone) |
| Dairy products | +2...+4°C | 3-5 days | Middle shelves |
| Ready meals | +2...+5°C | 2-3 days | Top shelves |
| Vegetables and fruits | +4...+6°C | 3-7 days | Bottom drawers |
| Frozen foods | -18°C and below | up to 12 months. | Freezer compartment |
Please note that dense loading of shelves may damage air circulation. Cold air must flow freely around the food in order for the temperature sensor to read the correct readings. Do not place hot pots inside - this will cause the compressor to work harder.
If you store a lot of vegetables, make sure there is ventilation in the drawers. Excess moisture at low temperatures will lead to rotting, and at high temperatures it will wilt. Adjust the air supply dampers if your model Paracelsus is equipped with a No Frost or mixed type system.
The influence of external factors and seasonal adjustment
Refrigerator Paracelsus, like any technology, is sensitive to ambient temperature. In summer, when the room is hot, the compressor takes longer to cool the chambers. In winter, on the contrary, the load may decrease. Some models have a “Winter-Summer” function, which optimizes the operation of the unit.
If the refrigerator is installed in an unheated room or in a kitchen with high temperature changes, the standard settings may be ineffective. In such cases, manual correction may be required. For example, in winter you can slightly reduce the power, and in summer you can increase it.
It is also important to consider the location of the refrigerator. Do not place it close to the wall or next to heating devices. Heat transfer should occur unobstructed through the rear radiator. A condenser clogged with dust also forces the system to work in increased mode, distorting temperature readings.
⚠️ Attention: Operating the refrigerator at ambient temperatures below +10°C or above +32°C is not recommended by manufacturers. This can lead to solidification of the oil in the compressor or overheating of the system.
Check the door seals. If the rubber band does not fit tightly, warm air will flow inside, and the sensor will constantly signal an increase in temperature, causing the motor to work without stopping.
Fault diagnosis and reset settings
Sometimes users are faced with a situation where the set temperature does not hold or the display shows an error. First of all, try performing a hard reset. To do this, unplug the refrigerator for 10-15 minutes and then turn it on again.
If the problem persists after rebooting, the temperature sensor or thermostat may have failed. In models with electronics, error codes often light up (for example, a flashing light at a certain interval). The decoding of the codes can be found in the instructions for the specific model Paracelsus.
A frequent reason for “under-freezing” or, conversely, over-freezing of products is incorrect calibration of the sensor. If you are sure that food spoils at +4°C, try shifting the settings by 1-2 degrees in the desired direction and observe the result during the day.
Regularly check the cleanliness of the internal ventilation openings. Their blockage with food or ice crust (in No Frost systems) disrupts heat exchange. In such cases, even a working compressor will not be able to maintain the set mode.
Why does ice freeze in the Paracelsus refrigerator, although the No Frost mode is set?
The No Frost system does not guarantee 100% complete absence of ice. Ice may appear if the door has been open for a long time, you have placed a hot product, or the seal has been broken. It is also possible that the drainage hole through which moisture should drain is clogged. Clean the drainage with a special stick or warm water.
Is it possible to transport the Paracelsus refrigerator while lying down?
Transporting it lying down is highly undesirable, since oil from the compressor may leak into the refrigerant circulation circuit. If there is no other way out, place the refrigerator on the side opposite to the outlet of the compressor tubes, and do not turn it on for at least 4-6 hours after installing it in a vertical position.
How often do you need to defrost the Paracelsus refrigerator?
Models with manual defrosting require cleaning from ice when the thickness of the crust reaches 5 mm (usually once every 3-6 months). No Frost systems require preventative defrosting and washing once a year to remove bacteria and odors, even if there is no visible ice.
What to do if the temperature alarm indicator is on?
A flashing red indicator or a sound signal means that the temperature in the chamber is higher than permissible. Check that the door is closed tightly, that the refrigerator is not overloaded, and that the compressor is running. If a few hours after closing the door the signal does not go off, there may be a freon leak or a sensor failure.
