Modern refrigerators brand Lumus are distinguished not only by their stylish design, but also by a well-thought-out microclimate control system inside the chambers. Correct temperature setting is a key factor influencing the safety of products, their taste and shelf life. Many users mistakenly believe that it is enough to simply plug in the device, but for the compressor and evaporator to operate effectively, precise calibration of the parameters is required.
Owners are often faced with a situation where the products in the main chamber freeze or, conversely, quickly deteriorate due to insufficient cold. In models Lumus an electronic control unit is responsible for these processes, which must be correctly programmed to suit your needs. Ignoring basic operating rules can lead to increased energy consumption and premature wear of the unit.
In this manual, we will analyze in detail the algorithms for setting temperature values for different compartments, explain the meaning of the indicators on the control panel and help avoid common mistakes. You will learn how to quickly switch between modes and understand how the system No Frost works in your device.
Control of the electronic display panel
The refrigerator control interface Lumus is usually located on the outside of the upper chamber door or at the end. The panel is a touch screen or a set of buttons with a digital display that displays the current parameters. Main screen shows the temperature in the refrigerator compartment, and when you press the corresponding button, in the freezer compartment.
To activate the setting mode, you must press and hold the "Temp" or "Fridge" button within 3 seconds. At this moment, a digital value will begin to flash on the display, which indicates that the device is ready to change parameters. If you do not perform any actions within 10 seconds, the system will automatically exit the settings menu, saving or canceling changes depending on the model.
⚠️ Attention: When setting up, avoid touching the panel with wet hands or sharp objects, as this may damage the touch layer or cause false alarms of the electronics.
Navigation is carried out using the "Up" and "Down" arrow buttons or by pressing the main selection key again.
Optimal values for the refrigerator compartment
The refrigerator compartment is designed for storing products that do not require freezing, but need refrigeration. Factory settings Lumus are often set to +3°C or +4°C, which is considered gold standard for most product groups. It is at these temperatures that the growth of bacteria slows down, but the structure of vegetables and fruits is not destroyed.
If you plan to store a lot of perishable products, such as fresh meat, fish or dairy products, the temperature can be lowered to +2°C. However, be aware that when setting values below +1°C there is a risk of water freezing in vegetables and some drinks located at the back wall.
- 🥦 For vegetables and fruits, the optimal range is +4..+6°C to retain moisture and crunch.
- 🥛 Dairy products and prepared foods are better preserved at +2..+4°C at middle shelves.
- 🍺 Drinks and sauces can be stored at +5..+7°C without loss of quality.
- 🥩 Fresh meat for short-term storage (1-2 days) requires a freshness zone with a temperature of about 0..+2°C.
Adjustment is made by selecting the appropriate number on display. Remember that the actual temperature inside the chamber may differ from the display readings depending on the load of products and the frequency of opening the door. Accurate calibration of sensors is only possible with the help of professional equipment in a service center.
Adjusting the freezing mode
The freezer compartment in refrigerators Lumus allows you to set the temperature in the range from -15°C to -24°C. The standard value for everyday use is -18°C. At this temperature, most microorganisms completely stop their activity, which allows you to store food for months.
The function Super Freeze (Super Freeze) is designed for quick freezing of fresh food. When this mode is activated, the compressor operates continuously, reducing the temperature to the lowest possible values (usually -24°C). This allows you to create an “ice crust” on products quickly, preserving their cellular structure and healthy juice during defrosting.
It is not recommended to keep the super freezing mode turned on constantly, as this leads to increased energy consumption and load on the compressor. After fresh food is completely frozen (usually after 24 hours), the function must be turned off manually or wait until it automatically returns to the previous settings.
☑️ Checking the freezing mode
Vacation function and energy saving
If you are planning a long absence, in refrigerators Lumus there is a special mode “Vacation” or “Vacation”. Its activation switches the refrigerator compartment to an economical operating mode with a temperature of about +15°C, which prevents the appearance of mold and unpleasant odors, but does not freeze food.
The freezer compartment continues to operate as normal, preserving frozen stocks. This solution is ideal for situations where you're going away for a week or two and won't be storing anything in the main compartment. Energy consumption in this mode is reduced significantly.
To turn on the mode, you usually need a long press (about 5 seconds) on the button with the image of a suitcase or the inscription "Eco". The mode indicator will light up to confirm activation. Do not forget to remove all perishable food from the main chamber before leaving.
⚠️ Attention: In the "Vacation" mode, the refrigerator door should remain slightly open or be thoroughly washed and dry to avoid mustiness, unless the model provides complete insulation of the chamber.
Table of recommended temperatures modes
For the convenience of users, below is a summary table to help navigate the settings for various types of products. These data are based on manufacturer's recommendations Lumus and general food storage standards.
| Product type | Recommended temperature | Shelf life (approximate) | Placement area |
|---|---|---|---|
| Fresh meat/Fish | 0°C.. +2°C | 1-3 days | Bottom shelf / Freshness zone |
| Dairy products | +2°C.. +4°C | 3-7 days | Middle shelf |
| Vegetables and fruits | +4°C.. +8°C | 5-10 days | Bottom drawer |
| Frozen foods | -18°C and below | up to 12 months | Freezer |
| Ready meals | +2°C.. +5°C | 2-4 days | Top shelf |
Use Correct storage areas allow you to extend the life of food without the need for extreme cooling of the entire volume of the refrigerator. Please note that dense loading of chambers can interfere with air circulation, so do not overcrowd the refrigerator.
Common errors and their elimination
Often users encounter the problem that The set temperature does not correspond to the sensations or readings of the thermometer. One common reason is installing the refrigerator too close to a wall or heat sources. In such conditions, the system cooling works with overload, not having time to dump heat through the condenser.
Another mistake is blocking the ventilation holes inside the chamber with products. Cold air should circulate freely throughout the entire volume. If you close the holes, the temperature sensor will show normal, while the far corners will be warm.
It is also worth mentioning that the door is often opened. Every time you open the refrigerator Lumuswarm, moist air comes in, causing the compressor to work harder. Try to minimize the time when the door is open.
⚠️ Attention: If, after adjusting the temperature, the refrigerator makes unusual sounds or does not cool within 24 hours, you must contact a service center, as there may be a refrigerant leak or a thermostat malfunction.
Why does it jump temperature?
The temperature may fluctuate due to defrost cycles (on No Frost models) or when loading a large amount of warm food. This is a normal operating process, the system itself stabilizes the climate after a few hours.
Frequently asked questions (FAQ)
How to reset the Lumus refrigerator to factory settings?
To reset the settings, you must disconnect the refrigerator from the power supply for 10-15 minutes. Some models require pressing the "Freeze" and "Fridge" buttons simultaneously for 5 seconds, but it is better to check the exact combination in the instructions for the specific model, as the firmware may vary.
Why is the temperature alarm indicator on?
A flashing indicator or sound signal usually means that the temperature inside the chambers has risen above the safe limit. This could happen when the door is opened for a long time, a power outage or breakdown. Check that the door is tightly closed and make sure that the power cord is plugged into the outlet.
Is it possible to quickly freeze hot soup in the Super Freeze mode?
It is strictly not recommended to put hot or warm food in the refrigerator, even when Super Freeze is turned on. This creates a tremendous load on the compressor and increases the temperature in all chambers, which can lead to spoilage of already frozen products. Let the dish cool to room temperature.
How often do you need to defrost a Lumus refrigerator with No Frost?
The No Frost system involves automatic removal of moisture, so such refrigerators do not need complete defrosting. However, once every 6-12 months it is recommended to carry out preventive washing and disinfection of the chambers with disconnection from the network to remove dust from the condenser and check the seals.
