Refrigeration equipment for trade brand Pozis is deservedly popular due to the reliability of its compressors and well-thought-out ergonomics of the internal space. However, in order for the food to remain fresh for as long as possible, and the compressor not to wear out ahead of time, it is necessary to set the temperature correctly. Many owners encounter difficulties during the initial setup or after defrosting, not fully understanding the logic of the thermostat.
In this article we will analyze in detail the mechanics and electronics of climate control in various models Pozis refrigerators. You'll learn how to interpret indicator readings, why your freezer may not be freezing cold enough, and how to avoid common operating mistakes. Correct calibration is the key to long service life of the equipment.
There are two main types of temperature control in units of this brand: mechanical (using a rotary knob) and electronic (digital display). The algorithm of actions directly depends on the type of your model. We will consider both options, paying attention to the nuances that are often missed in standard user manuals.

Principles of operation of the thermostat and temperature zones
The main element responsible for the microclimate inside the chamber is thermostat. In mechanical models, it is a device that opens the electrical circuit when a certain evaporator temperature is reached. In digital models, this function is performed by sensors that transmit data to the control module. Understanding this difference is critical for correct settings.
Inside the refrigerator compartment, the temperature is unevenly distributed. It is always colder at the back wall, where the evaporator is located, than at the door. Therefore, it is important to place products with this feature in mind. For example, it is better to store dairy products and meat closer to the back wall, and drinks or sauces on the door shelves.
⚠️ Attention: Never block the ventilation holes inside the chamber with food. Impaired air circulation will lead to local overheating and erroneous readings from temperature sensors.
The optimal mode for storing most products is considered to be a range from +2 to +5 degrees Celsius. Under such conditions, bacteria multiply slowly, but the food does not freeze. If you notice that the milk at the back wall is covered with ice, it means that the mode is selected too aggressively.
For the freezer, the standard value is -18 degrees Celsius. It is at this temperature that most bacteria completely cease their activity, and products can be stored for months. Lower temperatures, for example -24, are used only for quick freezing of fresh food.
Setting up a mechanical thermostat
Most classic models Pozis, such as series Rowan or World, use a rotary regulator. It is usually located inside the refrigerator compartment, in the upper right corner, or on the top panel of the case. The scale can be digital (from 1 to 5 or from 1 to 7) or alphabetic (Min/Max).
It is important to remember the key feature: the numbers on the scale do not indicate degrees, but cooling intensity. The higher the number, the colder it will be inside. Setting the knob to the "5" or "Max" position causes the compressor to work almost without stopping, which can lead to freezing of products.
For standard storage mode, it is recommended to set the knob to the middle position. If the scale has values from 1 to 5, "3" would be optimal. If from 1 to 7, choose "3" or "4". This ensures a balance between cooling quality and energy consumption.
☑️ Checking the mechanical setting
If you set the regulator to minimum, but the food still spoils, the thermostat may be faulty or there is not enough refrigerant in the system. In this case, simply twisting the knob will not help solve the problem; a technician will need to diagnose it.
Control via an electronic display
Modern models Pozis, for example, series Smart or two-compressor options, are equipped with electronic control. On the front panel there is a display showing the current temperature in each chamber. Control is carried out using touch buttons or mechanical keys under the screen.
To change parameters, you must press the mode selection button (often indicated as Mode or the image of a snowflake/drop). After the indicator of the desired camera starts blinking, use the "+" and "-" buttons to set the desired value. Confirmation usually occurs automatically a few seconds after the last press.
| Display value | Actual temperature | Recommendation |
|---|---|---|
| +2... +4 °C | Optimal | Standard storage mode |
| +5... +7 °C | Increased | For short-term storage of vegetables |
| 0... +1 °C | Reduced | For meat and fish for 1-2 days |
| -18... -20 °C | Norm for freezer | Long-term storage freezing |
Electronics allows you to set the exact temperature in 1-degree increments, which is impossible to do mechanically. This is especially convenient in the summer, when the ambient temperature in the kitchen is high and more intensive operation of the compressor is required.
Super Freeze and Super Cool modes
In the arsenal of refrigerator functions Pozis there are accelerated cooling modes. Mode Super Freeze (Super Freeze) is intended for the freezer. When activated, the compressor operates continuously, ignoring the thermostat readings, in order to lower the temperature as quickly as possible.
This mode should be turned on in advance, before loading a large batch of fresh products, or immediately after loading if the products are already slightly frozen. Long-term operation in this mode (more than 24 hours) is not recommended, as this leads to excessive energy consumption and accelerated wear of the motor.
Mode Super Cool (Super cooling) is similar to the previous one, but works in the refrigerator compartment. It is useful when you have brought a lot of warm products from the store and you need to quickly cool the entire volume, preventing the heat from spreading to the already stored items.
⚠️ Attention: Do not leave the "Super" modes on all the time. In most models Pozis they turn off automatically after a certain time, but control will not hurt.
These modes are activated on the electronic display by a separate button with the corresponding symbol (usually a snowflake with stars). On mechanical models, there may be a separate red button or the extreme position of the regulator for this.
Factors affecting the temperature inside
Even a properly configured refrigerator can work ineffectively if external factors are not taken into account. First of all, this ambient temperature. If the refrigerator is located next to a radiator, stove, or in direct sunlight, it has to work at its limit.
The second important factor is the frequency of opening the doors. Every time you open a door, you let out cold air and let in warm, humid air. The compressor takes time to compensate for this heat gain. In families with children, this parameter often becomes critical.
- 🧊 Loading of chambers: a full refrigerator holds cold better than an empty one, since food accumulates cold.
- 🌡️ Tightness of seals: if the rubber on the door is worn out or dirty, the cold will escape constantly.
- ❄️ Presence of ice: a thick layer of ice on the evaporator acts as a heat insulator, interfering with the cooling of products.
It is also worth mentioning seasonality. In winter, when the apartment is cool, the refrigerator may work less often. In summer, on the contrary, work cycles increase. Some models Pozis have a climate class switch, but in household versions it is rare.
Why can’t you put it on hot?
Putting hot dishes causes a sharp jump in humidity and temperature. This leads to the formation of condensation, which freezes on the walls and causes the compressor to wear out. Always cool food to room temperature.
Diagnosing problems with temperature conditions
If you set the temperature according to the instructions, but the result does not meet expectations, you need to carry out diagnostics. The first sign of a malfunction may be constant operation of the compressor no shutdowns or, conversely, its complete rest with warm products.
Check whether the condenser (the grille at the back of the refrigerator) is not clogged with dust. A dirty heat exchanger cannot transfer heat efficiently, causing system pressure to rise and cooling to decrease. Cleaning with a vacuum cleaner or a soft brush often solves the problem of overheating.
Pay attention to the nature of the noise. The hum should be uniform. If clicking, gurgling or whistling sounds are heard, this may indicate problems with the refrigerant or the start relay, which directly affects the ability to maintain temperature.
| Symptom | Possible cause | Action |
|---|---|---|
| Water on floor | Drainage clogged | Clean the hole in the chamber |
| Ice in the refrigerator compartment | Faulty defrost sensor | Call a technician |
| Warm at the top, cold at the bottom | Fan faulty (No Frost) | Check the airflow |
| The compressor does not turn on | Electronics or relay failure | Check the power supply |
It is important to distinguish between normal operation and breakdown. For example, strong cooling of the side walls between the chambers in new models is normal; refrigerant circuits pass there to prevent condensation.
⚠️ Attention: If you smell burning or see sparking in the compressor area, immediately unplug the refrigerator. Further operation is prohibited.
Frequent questions and answers (FAQ)
Why does ice freeze in the Pozis refrigerator, although I did not open the door?
This may occur due to a loose door, a faulty seal, or breakdown of the defrost system (heating element or timer). Also check if the drainage hole through which moisture escapes is not clogged.
What temperature should you set in the summer?
In the hot season, it is recommended to set the thermostat to a value slightly above average (for example, “4” out of 5) to compensate for the high temperature in the room. Make sure that the refrigerator is kept away from heat sources.
What does the flashing indicator on the display mean?
Flashing usually signals an alarm. If the temperature is flashing, it means it is above normal. If the red indicator or alarm symbol is on, the door has been open for too long or the temperature in the chamber is critically elevated.
Is it possible to use a Pozis refrigerator on the balcony?
Most household models are designed to operate at ambient temperatures from +10 to +32 degrees (climate class SN-T). Operation at high temperatures will damage the compressor and seals.
How to defrost an electronically controlled refrigerator?
Unplug the appliance, remove the food and leave the doors open. The electronics will be reset, but after turning on you will need to re-set temperature mode according to your preferences.
