Modern refrigeration units Polair are famous for their reliability and well-thought-out control system, but correct temperature setting is critical for the long-term preservation of products. The owner of the equipment is often faced with the need to change standard factory settings in order to adapt the operation of the unit to specific operating conditions or the volume of loaded products. Understanding the operating principles of the thermostat allows you not only to save energy, but also to significantly extend the service life of the compressor.
The setup process may vary depending on the series of equipment: be it professional cabinets for public catering or household models for the home. In this article, we will analyze in detail the algorithms of actions for various control panels, explain the meaning of the indicators and help to avoid common mistakes that can lead to damage to the contents of the chambers.
Principles of operation of the thermostat and types of control
All refrigerators Polair are divided into two main groups according to the type of control: electromechanical and electronic. In the first models, the setting is made by mechanically turning the handle, where the numbers from 1 to 7 indicate the degree of cooling, not degrees Celsius. Here thermostat works on the principle of opening the circuit when a certain temperature inside the chamber is reached.
Electronic systems, such as Micro 40 or DM 101provide the user with precise digital control. They are equipped with sensors that continuously monitor the state of the environment and send signals to controller. This allows you to maintain the temperature with an accuracy of 0.1 degrees, which is especially important for storing perishable goods or medicines.
⚠️ Attention: In electromechanical models, the number “7” means maximum cooling, and “1” means minimum. Setting the regulator to maximum in a warm room can lead to continuous operation of the compressor and its overheating.
Digital controllers also have built-in protection against power surges and a memory function that saves settings during a short-term blackout. Understanding the difference between these systems is necessary for correct initial calibration equipment.
Temperature adjustment in industrial cabinets (ShH, ShN, Kama Series)
Professional equipment Polair for catering and shops are most often equipped with microprocessor controllers. The standard procedure for setting the temperature in such units requires sequential steps. First, you must press and hold the "SET" (or "SET") button for 3-5 seconds until a flashing indicator appears on the display.
After activating the editing mode, using the "Up" and "Down" arrow buttons, the user sets the desired value. After selecting the desired number, you must press "SET" again to confirm.
☑️ Checking the cabinet settings
There is also the possibility of quick adjustments without entering the deep menu, if the control panel allows short-term changes in settings. In some models of the series Kama or Polyus (compatible with Polair), you can simply briefly press the adjustment button, and after 10 seconds the settings will be saved automatically.
Adjustment in household models and two-chamber refrigerators
In household refrigerators Polair the interface can be represented by either a touch panel or classic buttons. Changing the operating mode usually requires pressing the "Mode" or "Mode" button to switch between compartments (refrigerator or freezer). The indicator of the current compartment will start blinking on the display.
Next, using the adjustment keys, set the required value. The optimal temperature for the refrigerator compartment is considered to be from +2 to +4 degrees Celsius. For the freezer, the standard is -18 degrees and below. After setting the parameters, the device will enter operating mode in a few seconds.
Some models are equipped with a “Super Freeze” or “Quick Freeze” function, which temporarily lowers the temperature to minimum values to quickly freeze fresh food. It is not recommended to use this mode constantly, as it increases the load on refrigerant and the system as a whole.
Table of recommended temperature conditions
Different types of products require different storage conditions. An incorrectly set temperature can lead to the growth of bacteria or, conversely, to damage to the structure of products due to crystallization of moisture.
| Product type | Recommended temperature | Shelf life (approximate) | Area in the refrigerator |
|---|---|---|---|
| Fresh meat and fish | from 0°C to +2°C | 1-3 days | Bottom shelf / Zero zone |
| Dairy products | from +2°C to +4°C | 3-7 days | Middle shelves |
| Vegetables and fruits | from +4°C to +6°C | 3-10 days | Bottom drawers |
| Frozen semi-finished products | below -18°C | up to 6 months | Freezer compartment |
Compliance with these parameters ensures (guarantees) not only the safety of food, but also the correct operation of the evaporator. Overloading the chamber with warm products requires a temporary decrease in temperature, but after the background has stabilized, the values should be returned to normal.
Deciphering error codes and indications
Electronic control systems Polair are capable of diagnosing faults and displaying their codes on the display. The most common signal is a flashing temperature indicator or the appearance of letters such as "AL" (Alarm) or "E" (Error) with a number.
The code "E1" or "E01" most often indicates a malfunction of the evaporator temperature sensor. If you see "E2", this may indicate problems with the sensor in the refrigerator compartment. In such cases, the system may go into emergency mode, trying to maintain cooling at time intervals.
⚠️ Attention: If the red indicator is on on the display or the temperature is flashing, this is a signal that the actual temperature inside the chamber is higher than the set one. Check the tightness of the door and the integrity of the seal.
To reset the error, sometimes it is enough to turn off the device from the network for 10-15 minutes. However, if the code appears again after switching on, a professional diagnostics and possibly replacement of the sensor element is required.
Setting features during hot periods and when fully loaded
In the summer or when installing the refrigerator in a room with high air temperature heat exchange is violated. Under these conditions, the standard settings may not provide sufficient cooling. It is recommended to check the ventilation of the condenser and, if necessary, increase the operating mode slightly.
When the chamber is fully loaded with products, air circulation becomes difficult. Cold air should freely wash all shelves. If you have filled the refrigerator to capacity, it makes sense to temporarily set a lower temperature, and after stabilizing the processes, return the settings to normal mode.
Why does the refrigerator take a long time to gain temperature?
When first turned on or after defrosting, the Polair refrigerator may take from 4 to 12 hours to reach operating mode. At this time, you should not completely load the chamber with products.
It is important to ensure that the products do not block the outlet openings of the air ducts (in No Frost systems). Blocking the air flow will lead to local overheating and incorrect operation thermostat.
Frequently asked questions (FAQ)
What to do if the temperature in the Polair refrigerator does not hold?
First check the tightness of the door closure and condition sealing rubber. If the door closes tightly, the controller may have failed - try rebooting the device by unplugging it for 15 minutes. If the problem persists, there is likely a freon leak or a compressor malfunction.
How to convert Fahrenheit to Celsius on the display?
Usually, switching units occurs by simultaneously pressing two buttons (for example, "Mode" and "Down") in the off state or through the service menu. The exact combination depends on the model of the controller installed in yours. Polair.
Is it possible to adjust the temperature remotely?
Basic models do not have this function. However, modern professional cabinets may be equipped with telemetry modules that allow monitoring of parameters via a computer or smartphone, but setting the temperature setpoint often remains a local function for safety.
Why is the freezer running but the refrigerator compartment is warm?
This is a common problem in systems with a single compressor. The cold air supply duct may be clogged, the blower fan is faulty, or the defrost sensor may be faulty. Also check to see if the Super Freeze mode is set, which prioritizes cooling of the freezer.
