Correct temperature adjustment mode in refrigeration equipment Pozis is a critical condition for long-term preservation of products and safe operation of equipment. Incorrectly set parameters can lead to rapid spoilage of food, the formation of ice, or, conversely, excessive energy consumption due to constant operation of the compressor. The owner must clearly understand what type of cooling system is installed in his model, since the algorithm of actions during setup directly depends on this.
Modern Russian-made units are equipped with both classic mechanical regulators and advanced electronic control systems microclimate. In the first case, the user needs to focus on the division scale, in the second - on the digital display readings. Ignoring the manufacturer's instructions often causes the breakdown of expensive components, such as a compressor or evaporator.
In this article we will analyze in detail the process of setting optimal values for various chambers, consider the nuances of the system No Frost and static drip defrosting. You'll learn how to diagnose a thermostat problem and when to call a service center instead of trying to fix the problem yourself. A competent approach to setting will extend the life of your household appliance.
Determining the type of climate control system
The first step before starting any manipulations is a visual inspection of the inside of the refrigeration chamber. It is here, usually on the top wall or in the corner, that the control is located. In models Pozis there are two main types of regulators: mechanical rotary and electronic touch or push-button. You can instantly distinguish them: the mechanical one is a round knob with numbers from 1 to 5 (or 7), and the electronic one is a display with buttons.
Mechanical thermostats work on the principle of changing resistance depending on the temperature inside the chamber. When you turn the knob, you change the threshold at which the compressor turns off. This is a reliable but less accurate system that requires periodic checking of the actual temperature using an external thermometer. Electronic systems control the process is much more precise, allowing you to set the value in steps of one degree.
⚠️ Attention: It is strictly forbidden to apply excessive force when turning the mechanical thermostat knob. It is not necessary to bring the regulator all the way to the extreme position, this can lead to mechanical damage to the shaft or displacement of the sensor calibration.
If you see indicators or a screen on the front panel of the refrigerator, it means that control is carried out through electronics module. In such models, for example series RK-168 or RD-408, settings are made by sequentially pressing buttons.
Setting up a mechanical thermostat
For owners of classic models Pozis with a rotary knob, the adjustment process seems simple, but has its own technical features. The numbers on the scale do not indicate degrees Celsius, they indicate the intensity of cooling. One corresponds to the minimum cold, and the maximum number (usually 5 or 7) corresponds to the maximum power of the compressor.
The factory setting is most often set to the average value, which is suitable for most situations. If you loaded the refrigerator with a large amount of warm food after purchase, you can temporarily increase the power, but then be sure to return the regulator to normal mode. Constant operation at maximum leads to freezing of the evaporator and reduction of engine life.
The optimal position of the handle is considered to be the middle value of the scale. However, during the hot season or when there is high humidity in the room, it may be necessary to shift the regulator one notch towards increased cold. In winter, on the contrary, when the room is cool, the load on the system can be reduced.
☑️ Checking the mechanical settings
Temperature adjustment in electronic models
Electronic control in refrigerators Pozis provides the user with advanced capabilities. Here you can see the exact temperature in degrees Celsius and set it with high precision. To enter the setting mode, you usually need to press and hold the thermometer button or the special “Adjustment” button for 3-5 seconds.
After activating the setting mode, the current value will begin to flash on the display. Using the “+” and “-” buttons or the mode switch button, set the required parameter. Confirmation of a selection often occurs automatically if no new commands are received within 10 seconds, or a single press of the confirmation button is required. In two-chamber models with one compressor, the temperature setting in the freezer can be done separately or associated with the general mode.
Modern models can be equipped with the “Vacation” or “Eco” function, which automatically adjusts the operation of the unit in an economical way. In this mode, the temperature in the refrigerator compartment rises to +15°Cwhich prevents odors, but preserves food, and the freezer continues to operate as normal.
What does the flashing indicator mean?
If the temperature indicator on the display flashes, this is an alarm. Most often this means that the temperature inside the chambers is higher than the established norm. Check that the door is closed tightly, that the refrigerator is not overloaded with food, and that the compressor is running. If the flashing does not stop after cooling, the sensor may be faulty.
Optimal temperature conditions for storage
Understanding what temperature is required for different types of food will help you set up the refrigerator Pozis most efficiently. There is no single ideal value for all cases, but there are generally accepted standards to ensure food safety. In the refrigerator compartment, the optimal range is considered to be from +2°C to +6°C.
The freezer compartment requires more stringent conditions. For long-term storage of meat, fish and semi-finished products, the temperature should not be higher -18°C. With this regime, bacteria do not multiply, and products retain their taste and vitamins for up to 12 months. Short-term storage (up to 3 days) is allowed at -6°C.
| Product type | Recommended zone | Optimal temperature | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat and fish | Lower shelf (freshness zone) | 0..+2°C |
1-2 days |
| Dairy products | Middle and upper shelves | +2..+4°C |
3-5 days |
| Vegetables and fruits | Drawers at the bottom of the chamber | +4..+8°C |
3-7 days |
| Ready meals | Middle shelves | +2..+6°C |
1-2 days |
It is important to take into account the distribution of cold inside the chamber. It is always colder near the walls than in the center. Therefore, it is better to place perishable products closer to the back wall, but not close to it, so as not to disturb the air circulation. Door shelves are the warmest place, suitable for sauces, drinks and eggs, but not for milk or meat.
Features of setting up the No Frost system
Refrigerators Pozis with the system No Frost (or “Full No Frost”) do not require manual defrosting, so as equipped with automatic evaporator defrost cycles. Setting the temperature in such models has a nuance: air flows are forced to circulate, so the temperature equalizes faster, but may be drier.
When first turned on or after defrosting, the system requires time to stabilize. It is not recommended to load the chamber with products during the first 2-4 hours of operation. Make sure that the ventilation holes inside the chamber are not blocked by food, otherwise the sensors will read incorrect data and the compressor will work overload.
If you notice that the products in the blowing area (usually at the back wall) are frozen, and warmer near the door, try changing the arrangement of containers. Some models Pozis provide for adjustment of the cold air damper, which is located under a plastic cover on the rear wall. Shifting the damper lever allows you to increase or decrease the flow of cold from the freezer compartment.
Diagnostics and elimination of temperature problems
Even a properly configured refrigerator may not work correctly due to external factors or wear of parts. If you have set the average values, more than 6 hours have passed, and the temperature does not correspond to the set one, you need to carry out diagnostics. A common cause is a loose fit of the door seal.
You can check the seal using a simple sheet of paper. Clamp the sheet with the door around the perimeter: if it pulls out easily without resistance, it means the seal is broken. In this case, adjusting the thermostat will not help - the seal needs to be replaced or the door leaf should be aligned. Also check if anything is preventing the door from closing (plate, bag).
⚠️ Attention: If the compressor runs continuously for more than 24 hours and the temperature does not drop to the set temperature, or, conversely, the refrigerator is silent and warm inside, these are signs of a malfunction. There may be a freon leak, a broken thermostat, or a clogged capillary system. Further operation in this mode is dangerous for the engine.
Another reason for unstable temperature is the location of the refrigerator. If Pozis stands close to the wall or next to heating devices, heat exchange is disrupted. The rear radiator (condenser) must have free air access to release heat. The minimum distance to the wall should be 5-10 cm.
Frequently asked questions (FAQ)
Why does ice freeze in the Pozis refrigerator, even if the minimum temperature is set?
Ice formation at the minimum setting (number 1) may indicate a malfunction of the thermostat, which is “stuck” in the on position, or a refrigerant leak, which is why the compressor runs non-stop. Also check whether the drainage hole for removing melt water is not clogged.
What value should you set on the thermostat in the summer?
In the summer, when the ambient temperature in the room is high, it is recommended to slightly increase the load on the refrigerator. For mechanical controls, this means moving the knob towards higher numbers (for example, from 3 to 4), but not to the maximum. For electronic models, leave the standard ones +4..+5°C, the system itself will adjust the operating time of the compressor.
Is it possible to quickly cool drinks by setting the maximum cold?
For a short time (for 1-2 hours) you can turn on the super-freeze or maximum cold mode, if such a function is available. However, you cannot keep the refrigerator in this mode all the time: this will lead to freezing of food in the refrigerator compartment and rapid wear of the compressor. After cooling, return the settings to normal.
Why are there different temperatures in different corners of the refrigerator compartment?
This is a physical feature of the operation of static refrigerators. It’s always colder near the back wall (where the evaporator is located), and warmer near the door. In models with the system No Frost the temperature difference is smaller due to the fan, but it still exists. Place products taking into account this gradation.
