Correctly set temperature conditions is the foundation for the long service life of your refrigeration equipment Pozis and the safety of the products you store in it. Many owners mistakenly believe that it is enough to simply plug the device into the network, but ignoring the nuances of the thermostat operation can lead to rapid spoilage of food or increased energy consumption.
Equipment owners Pozis often face a dilemma: what value to turn the thermostat knob to so that it is cool in the main chamber, and the food in the freezer freezes deep enough. The answer depends on many factors, including the model of your device, the time of year and the number of loaded products.
In this article we will analyze in detail what indicators are considered the norm for different departments, how to properly adjust mechanical and electronic control systems, and also provide a table of shelf life for different categories of products at different temperature conditions.
Optimal temperature indicators for different departments
Modern refrigerators Pozis, be they classic models with a drip system or more advanced options with technology No Frost, are designed to maintain a certain climate inside the chambers. In the main refrigerator compartment, the ideal range is considered to be from +2 to +6 degrees Celsius.
This range of values is due to natural air circulation: at the back wall, where evaporatoris located, it is always colder than at the door. That is why it is important to arrange food correctly so that perishable items do not end up at risk.
⚠️ Attention: If you notice that food freezes at the back wall of the main chamber, and milk turns sour at the door in one day, this is a signal of a problem with air circulation or a malfunction of the thermostat, and not something that is needed urgently change settings.
The freezer should provide a temperature no higher than -18 degrees Celsius. It is this threshold that allows you to preserve the fiber structure in meat and fish, and also prevents the proliferation of bacteria for a long time. Some models Pozis with a function Deep Freeze are capable of briefly lowering the temperature to -24 degrees for quick freezing of fresh food.
In the freshness zone, if it is provided for by the design of your model (for example, in series RD or RK), the temperature should be kept around 0...+2 degrees. This is the “golden mean” that allows you to store meat, fish and cheeses for several days without freezing, preserving their taste.
How to set up a mechanical thermostat
Most refrigerators Pozis are equipped with a mechanical thermostat, which looks like a rotary knob with a digital designation from 1 to 5 (or from 1 to 7 in some modifications). It is important to understand that the numbers on the scale do not mean degrees Celsius
The number "1" corresponds to the minimum cooling capacity (the chamber is warmer), and the maximum number (5 or 7) corresponds to the maximum (the chamber is colder). For everyday use in a standard kitchen, it is recommended to set the regulator to the middle position.
Let's consider an approximate breakdown of positions for a typical 5-stage regulator:
- ❄️ Position 1-2: Minimum cooling mode. Suitable for the winter period, if the refrigerator is in an unheated room, or with a very small load of food.
- ❄️ Position 3: Normal operation mode. Optimal for most situations when the temperature in the kitchen is +18...+25 degrees.
- ❄️ Position 4-5: Maximum cooling mode. It is used in the summer in hot weather, when the chamber is fully loaded with products, or when it is necessary to quickly cool a large amount of warm (but not hot!) products.
Adjustment is smooth. Do not turn the knob immediately from “1” to “5”. After each change of position, you must wait several hours for compressor the new cycle to work and the temperature to stabilize.
Electronic temperature control control
In more expensive and modern models Pozis, such as series Smart or Miracle, the mechanical handle is replaced by an electronic control module with a digital display. Here the adjustment is made with an accuracy of a degree, which gives the user complete control over the microclimate.
Usually the control panel is located on the top of the door or inside the chamber. To change parameters, touch buttons or mechanical keys are used. In some models, to activate the setting mode, you need to hold the button for 3-5 seconds.
Electronics allows you to set separate parameters for the refrigerator and freezer compartments independently of each other. Standard factory settings, as a rule, are already optimized by the manufacturer:
- 🌡️ Refrigerator: default is +4°C.
- 🌡️ Freezer: default is -18°C.
⚠️ Attention: During a power outage or power surges in the network, the electronic control board may go astray. Always check the current settings on the display after power has been restored.
The advantage of electronic control is the presence of alarm indicators. If the temperature inside the chamber deviates from the set temperature by more than 2-3 degrees for a long time, a warning symbol will light up on the display, and in some models a sound signal will sound.
What to do if the display is on, but the buttons do not respond?
In some models, Child Lock is activated. To remove it, you usually need to press and hold a button with a lock icon or a combination of buttons (for example, "Mode" and "Temp") for 5 seconds. It is better to find detailed instructions for your specific model in the technical data sheet.
The influence of external factors and seasonal adjustment
The refrigerator Pozis is not an isolated system, it actively interacts with the environment. Room temperature, direct sunlight and proximity to heating devices directly affect the load the compressor experiences In the summer, when the ambient temperature in the apartment rises above +25 degrees, heat exchange becomes more difficult. During this period, it is recommended to switch the mechanical regulator to higher values (4 or 5) to compensate for the heat gain. Otherwise, the refrigerator will work almost non-stop, trying to achieve the set parameters, which will lead to overheating of the motor..

Otherwise, the refrigerator will work almost non-stop, trying to achieve the set parameters, which will lead to overheating of the motor.
In winter, the situation is the opposite. If the refrigerator is in a cool area (for example, in a hallway or on an insulated loggia, where the temperature is about +10...+15 degrees), the thermostat may “think” that it’s already cold inside and rarely turn on the compressor. This may cause the freezer to defrost. In such cases, the regulator is set to minimum (1 or 2), but the condition of the products is monitored.
It is also important to take into account the location of the equipment:
- ☀️ Direct sunlight: The housing is heated, causing the cooling system to work more intensely. If you cannot move the refrigerator, use thick curtains or blinds.
- 🔥 Proximity to the stove or battery: It is strictly not recommended to place the refrigerator closer than 50 cm from heat sources. This disrupts the heat dissipation of the condenser.
- 💨 Ventilation: The gap between the back wall of the refrigerator and the wall must be at least 5-7 cm for free air circulation.
Table of food storage at different temperatures
Understanding which foods feel best at what temperature will help you set up your refrigerator Pozis as efficiently as possible. There is no universal value for all shelves, so it is important to properly zone the space.
Below is a table showing the dependence of shelf life on temperature conditions. Please note that the data is relevant for fresh products of good quality.
| Product type | Optimal temperature (°C) | Shelf life (days) | Recommended place |
|---|---|---|---|
| Fresh meat (beef, pork) | 0 ... +2 | 2-3 | Freshness zone / Bottom shelf |
| Fish and seafood | -1 ... +1 | 1-2 | Freshness zone / Closer to the back wall |
| Dairy products (milk, kefir) | +2 ... +4 | 3-5 | Middle shelves (not on the door!) |
| Vegetables and fruits | +4 ... +8 | 5-10 | Vegetable drawers below |
| Ready meals (soups, salads) | +2 ... +5 | 2-4 | Top shelves |
Violation of the storage temperature conditions can lead not only to loss of taste, but also to the proliferation of pathogenic microorganisms. Meat and fish products are especially sensitive to heat, which at temperatures above +6°C begin to quickly deteriorate.
Dairy products stored on the door (where the temperature is higher due to frequent opening) may sour faster than the specified period. For them, it is better to highlight the central part of the main chamber, where the climate is most stable.
Diagnostics of problems with temperature conditions
Sometimes it happens that you set the correct settings, but the refrigerator Pozis stops freezing or, conversely, turns everything into ice. This may indicate a technical problem that requires intervention.
If the chamber is too warm (above +10°C) and the compressor runs continuously or does not turn on at all, a possible cause may be a refrigerant leak (freon). In this case, adjusting the thermostat will not help - you need to call a technician to refuel or find the leak.
Excessive freezing of the back wall or products ("fur coat") in models with a drip system may indicate a loose fit. door seal. If the rubber has dried out or become dirty, warm, moist air enters the chamber, which condenses and freezes.
☑️ Checklist
In models with a system No Frost a frequent problem is the failure of the defrost system (heating element, timer or defrost sensor). In this case, the evaporator becomes overgrown with ice, the air stops circulating, and the temperature in the chamber rises, although the compressor can work.
⚠️ Attention: If you hear the thermostat clicking, but the compressor does not start, or the motor hums, but does not pick up speed, immediately disconnect the device from the network. Further operation may lead to burnout of the motor winding.
Frequently asked questions (FAQ)
Why does ice freeze on the back wall in the Pozis refrigerator?
In models with a drip system ("crying wall"), ice periodically freezes on the back wall during operation compressor is a normal process. The ice melts when the motor is turned off and the water flows into the drain. If the ice does not melt and turns into a block, check if the drainage hole is clogged and make sure that you do not put hot foods inside.
What temperature should you set in the Pozis refrigerator in the summer?
In the summer, when the room temperature is high, it is recommended to set the mechanical thermostat to a position close to the maximum (numbers 4 or 5 out of 5 possible). This compensates for heat gain and allows the compressor to cope with the load. In electronic models, just leave the standard +4°C, the system will automatically adjust the operating time.
Is it possible to store watermelon in the Pozis refrigerator?
Yes, you can, but not for long. The optimal temperature for storing watermelon is about +1...+3 degrees. At lower temperatures, the pulp may lose flavor and texture. It is better to store it on the bottom shelf or in a vegetable drawer, if size allows, for no more than 3-5 days.
What does the flashing temperature indicator on the display mean?
A flashing indicator usually signals an alarm. This may mean that the door has been open for too long, or the temperature inside the chamber has risen above a critical level (for example, after defrosting or a long blackout). If the indicator does not stop flashing after closing the door and stabilizing operation, diagnostics of the sensors may be required.
Is it necessary to defrost the Pozis No Frost refrigerator?
The No Frost system (no frost) involves automatic removal of moisture, so they do not require regular defrosting “until the last piece of ice”. However, sanitary defrosting and washing is recommended 1-2 times a year to remove odors and bacteria. In this case, it is necessary to completely turn off the power.
