Refrigerated display cases, unlike classic refrigerators and chests, require setting the temperature and operating mode. This is due to the fact that refrigerated display cases can store completely different products that require different temperatures. To find out how to set up your refrigerated display cabinet, read the instructions for use.
For meat and fish, they usually set -2 degrees, for cakes and pastries +7, for vegetables and fruits +8 or more. Also, a lot depends on the humidity in the room and in the showcase itself. Correctly adjusted and adjusted, it allows products not to lose their presentation for several days, does not weather them, and itself is not covered with drizzle and condensation.
Remember that refrigerated display cases are designed for temporary storage of food. This means that the goods in it must be regularly changed, and unsold items must be sent to cabinets or lari for storage. Some devices, such as Cryspi freezers, allow the temperature to be lowered to -8 degrees outside of working hours, which significantly extends the shelf life of the goods. But more often than not, such a function is the exception, not the rule.
How to adjust the temperature in the refrigerated display case
Refrigeration equipment is a complex system that should be configured and maintained by a professional. General information on setting the temperature regime is in the operating instructions. Be sure to study it before starting work. If something is unclear to you, then it is better to contact the master - this will help to avoid further expensive repairs.
Setting the temperature and programming the showcase is done through the control unit. It is usually located at the bottom of the shop window from the seller's side. Most modern models are configured via the remote control - from it you can set the operating temperature and operating modes. Tuning through a block requires skill. Determine what temperature should be in your showcase and set it from the remote control. The showcase has its own thermometer, which shows the current temperature - the program and physical temperature must be the same.
There are often cases when the real and programmed temperatures differ from each other. This situation arises due to the pollution of the heat exchanger: it is covered with ice, dust, various debris and grease. It is necessary to monitor its cleanliness and at least once a month to do a "general cleaning" in the window. Freezers Ariada have an automatic defrosting system - you need to connect a special drain to them for proper operation. Other display cases just need to be unplugged and washed with warm water and baking soda.
How to set the temperature in a refrigerated display case
The initial temperature adjustment will be carried out by a specially trained person after installing the display case. Consult with him about this process - usually there is nothing complicated about it. Raising and lowering the temperature from the remote control is generally carried out with one button (like the volume on a TV). Setting the temperature through the block is more difficult, since any error can lead to zeroing the program. Also, the settings may get lost if the power goes out at the moment when you change the program. In such cases, you will have to call a professional who will completely reprogram the device.
How to lower the temperature in a refrigerated display case
Sometimes situations arise when the temperature in the display case does not drop to the required one. Why is this happening? There can be many reasons - a damaged compressor, low pressure or refrigerant leakage, clogging of the heat exchanger with ice or dirt, loose curtains. If the temperature does not drop to the required level, then defrost the showcase, wash the heat exchanger well, remove dust from the external compressor, clean the grooves along which the curtains go. If this does not help, then reduce the temperature through the remote control by a few degrees and see if it decreases in the display case. If so, just leave it as it is. If not, call a specialist.
Instructions
Turn on your computer and hold down the Delete key (F2, F8). After a while, the motherboard BIOS menu will open. To change the temperature of most devices, you can change the parameters of the fans. Press the F1 + Ctrl key combination, go to the Advanced Setup or Advanced Configurations menu.
Find the item responsible for the cooling parameters of the system. First, activate the Always On parameter opposite the Fan Mode item. This function prevents the fans from turning off. Find the Fan Speed item and set the required values in front of each cooler. Please note that your version of the motherboard may not have this function.
Press the F10 key and confirm the computer restart while saving the cooler operation parameters. If, after performing the procedures, the temperature of certain devices is still higher than normal, then try to reduce their performance. This usually concerns the central processor. This operation will lead to a decrease in the speed of the PC, therefore, this method is resorted to only in extreme cases.
Install the Speed Fan program and try using it to change the parameters of the fans. Activate the item "Autoadjustment". This will allow the utility to automatically increase the rotational speed of the blades of the necessary coolers to increase the degree of cooling of the devices.
If none of the above methods proved to be effective, then replace the required fan. Choose a device with more power. Remember, cooler size matters too. It is better to choose devices that allow you to configure them programmatically. Connect the selected fan to the desired device, turn on the computer and open the BIOS menu. Adjust the parameters of the new cooler.
Installing a new BIOS version is capable of opening up new possibilities for overlocking and working with the contents of the computer. Updates often fix old hardware bugs. The manufacturer often updates the BIOS version for its motherboards and offers users several installation paths - through DOS or directly from the system.
You will need
- - image of a bootable floppy disk Windows 98 or Windows ME;
- - the flasher and the BIOS firmware itself, downloaded from the motherboard manufacturer's website
Instructions
Create a boot disk by specifying the path to the boot floppy image file and adding the appropriate BIOS files to the disk. This can be done using Nero or Ultra ISO. The writing algorithm in these applications is similar. You need to open the system image file using the program and copy the files from the BIOS.
Reset the BIOS version. To do this, remove the battery from the motherboard for about 10 minutes, or select “Load Defaults BIOS” in the settings.
Insert the burned disc into the drive, restart your computer. The command line will start. Type "dir", the firmware and BIOS files will be shown. Copy the awdflash.exe and copy nf3916.bin files to the virtual disk using the copy commands (“copy awdflash.exe C:” and “copy nf3916.bin C:”).
Go to the appropriate section with the "C:" command. Set the options "awdflash nf3916.bin oldbios.bin / py / sy / cc / cp / cd / e".
Copy the old version back to the floppy disk (command "copy oldbios.bin A:") and restart the computer using the Ctrl, Alt and Del keyboard shortcuts. You can go into the BIOS and make the desired settings.
note
All actions are performed at your own peril and risk. If the firmware is unsuccessful, the computer will not be able to boot and will have to be carried to the service center. If you are not sure what the benefits of updating the BIOS will be, then it is best not to update it.
It is not worth updating the BIOS directly from Windows, as this may cause the system to completely inoperate. If you still want to "update" directly from the system, then do it in full accordance with the manufacturer's instructions. Also pay attention to the driver version, which must be at least version 6.66 (in the case of ASUS motherboards).

Bios(BIOS) is a set of programs built into a computer that are designed to start up the computer, configure its devices, and load the operating system. Like other software, the BIOS is configurable.
You will need
- - computer.
Instructions
Restart your computer to enter BIOS and press the Delete key at the first splash screen. There are other options for the keys on different motherboards, usually the splash screen will show a message like Press Del to enter setup. If another key is listed, such as F2, press it to enter BIOS.
Go to the Boot sector. BIOS commands are controlled using the cursor buttons and the Enter key. Find the Boot device parameter - it is responsible for the boot sequence from devices. Highlight the required parameter using the arrow and activate it with the Enter key. Select the hard drive to boot first, to do this, select First Boot Device and press Enter, select HDD, and press Enter again.
Go to the Power section to set the BIOS settings for the cooler and processor. Enable control of the system cooler as well as the CPU cooler. To do this, set the CPU Q-Fan Control option to Enabled, and select the Optimal value for the CPU Fan-Profile option.
Disable the boot-up logo from loading at startup to speed up system boot. To do this, go to the Boot sector, select the Boot Settings Cohfiguration option, find the Full Screen Logo item, set the value of this parameter to Disabled.
Go to the Standard CMOS Setup section to configure the system date and time and hard drive settings on your computer. The Integrated Peripherals section allows you to set interface preferences as well as additional system functions. Go to Power Management Setup to set power and power options. The function of binding to expansion cards of a computer can be set in the PnP / PCI Configurations section.
To determine the readings of system sensors (processor temperature, fan speed), go to the Hardware Monitor section. To restore BIOS defaults, go to Load Setup Defaults.
note
The commands in different BIOS versions may slightly differ from those described above.
Knowing the bios version is necessary first of all for reasons of its timely updating, which will optimize the operation of your personal computer. There are several ways to check the bios version. Read about some of them below.
Instructions
Start your personal computer. You can determine the BIOS version by reading it in the upper lines of information that is displayed on the screen at startup. If you do not have time to navigate and read the required text, restart your computer again. As you yourself have guessed, you cannot restart the computer indefinitely, so if you can't read it quickly, do the following.
Look at the BIOS version on the motherboard of your personal computer. To do this, you will have to open the system unit. Take a screwdriver and remove the screws that secure the side panel. Take it off.
Examine the motherboard carefully. Find its name. The BIOS version should be indicated next to it. By and large, this is a primitive way. Better start BIOS and see its version directly there. To do this, when the computer boots up, press the delete key. Then use the arrows to navigate to Main and then to System Information. There you will find comprehensive information regarding bios.
Go to the "Start" button menu. Select Run. At the command prompt, enter msinfo32. Then press enter. The System Information tool launches. In the corresponding section you can find all the information of interest about the bios. It is easier to navigate to System Information. Go to the "Start" button menu, select "All Programs", then "Standard" and "System Tools". In the latter, find the item "System Information".
Try Everest Ultimate Edition. She will provide you with similar information. Run the program, find the item "Motherboard". Go to it. In the central window, you will find all the bios data, including version, year of manufacture and manufacturer information.

Open the Hardware Monitor submenu, which is usually located on the Power menu. This submenu has different names in different BIOS versions, the most common of which are PC Health, H / W Monitor, and Status. In the window that appears, you can see the parameters you need. The CPU temperature will be displayed in the CPU Temperature line, and the motherboard temperature in the MB Temperature. Perhaps in this menu you will also see the temperature inside the system unit.
Each CPU model has its own temperature limit, but most do not exceed 75 ° C (167 ° F). To be sure, check the documentation for the CPU and motherboard. But it should be understood that if the processor temperature at low workload exceeds 60 ° C (140 ° F), you need to take a number of measures to reduce it, namely, clean the system unit from dust, which makes it difficult for air to circulate inside it, and change the thermal paste.
If this does not help, then it is worth considering buying a more efficient cooling system. By the way, the problem may lie not only in the cooling system, but also in the equipment itself, since PC components tend to overheat after prolonged use. It happens that there is no other way but to replace old components. It should also be borne in mind that when the user uses the BIOS, the PC does not perform complex calculations, during which the temperature of some components, in particular the central processor, rises significantly.
Press Esc to exit BIOS and, if required, confirm your intention with the Y key, and then press Enter. Remember that if you are an ordinary user, then you should not make any changes in the BIOS environment, as this can result in both unstable operation of the PC and its complete inoperability.

Among the incoming questions on malfunctions of refrigerators, there are often questions of the following content:
“Please advise what you can do or how to adjust the thermostat in the refrigerator Minsk 15 two-chamber. It is necessary that the refrigerator turns off at a temperature of +4 to +6 degrees. I tried to turn the thermostat knob myself; it turns off only at sub-zero temperatures. "
"Hello! After being connected to the network, the compressor works for 5-10 seconds and turns off. I tried to put a new starting relay, the same thing happens. "
Before connecting the refrigerator, it should be installed so that there is no rolling and the place of installation should be chosen correctly - for better cooling of the condenser of the refrigerator by the environment (air). Then, you need to carefully read the manual for the refrigerator. I believe that the content of this topic will touch upon the most basic (for refrigerators), which should be paid special attention to when operating a refrigerator. Let's start with the cycle time of the refrigerator.
Refrigerator cycle
The cycle of the refrigerator is understood as the time from the moment the motor-compressor is turned on, the duration of its operation and the time at which the motor-compressor is off. The cycle time, for most refrigerators, ranges from 8 to 15 minutes. The number of such cycles per hour, respectively, will be from 4 to 8. It should be noted that the duration of one cycle or the number of cycles per hour during the day will not be constant. That is, various factors affect the duration of the cycle and the number of cycles:
- air temperature in the apartment,
- the number of times the refrigerator and freezer was used,
- decrease or increase in temperature in the heating batteries of the apartment,
- The temperature control knob is moved
Now, let's take a closer look at how to correctly set the temperature in the freezer.
How to set the temperature in the freezer
The temperature in the freezer compartment is set according to the shelf life of the frozen food you have selected. The so-called gradations for refrigerators by temperature in the freezer have been established.
If the shelf life of frozen products is about three days, the temperature is set from minus 6 degrees and below. From minus 12 degrees and below, products must be stored for up to 3 weeks. From minus 18 degrees and below, the shelf life of products is up to 3 months.
Temperature-in the refrigerator compartment
The temperature for both the freezer and the refrigerator compartment (refrigerator compartment) is set using the thermostat knob, and it should be noted that the temperature in the refrigerator compartment is set automatically, due to the set temperature regime in the freezer compartment. Why is this happening - you ask? Yes, because the thermostat in the refrigerator does not respond to the temperature in the refrigerator compartment, but to the temperature in the freezer compartment, or rather, to the temperature of the evaporator wall, to which the thermoregulator bellows tube is attached. You should also be aware that the temperature in the refrigerator, with the set temperature regime, can vary from 6 to 7 degrees, depending on the factors that were given above. The thermostat knob is set approximately in the middle position (on the scale).
So, let's say with the middle position of the thermostat knob and at an air temperature in the apartment of +25 degrees, the temperature in the refrigerator compartment will be approximately +3.5 degrees, and in the freezer compartment (chamber) the temperature will be about minus 6.2 degrees. Such data, I cite from the technical literature (outlined material).
I would like to provide you with approximate temperature characteristics (for many types of refrigerators), that is, copy the graph on the Internet. Unfortunately, such data on the Internet is not accurate. Therefore, I will draw by hand the graphs of the temperature change in the refrigerator and freezer chambers (depending on the ambient temperature), and I will additionally add data to this topic.
How to check the temperature in the refrigerator
The temperature is measured in the refrigerator under basic conditions:
1. The refrigerator must be empty, ice molds must be removed,
2. Refrigerator accessories must be dry and thoroughly wiped clean,
3. When checking the temperature in the refrigerating chambers, the ambient temperature should be constant,
4. When measuring the temperature in the freezer, the thermometer should be centered on the freezer shelf,
5. When measuring the temperature in the refrigerating chamber, the thermometer is installed on the middle shelf of the refrigerating chamber,
6. If the temperature is measured with mercury or alcohol thermometers, it is necessary to take into account the possibility of errors in the direction of increasing the temperature (when opening the refrigerator).
The temperature should be measured once per hour, with the refrigerator set. Then, you need to compare (compare) the difference in measurements for two hours. This difference should be no more than 0.5 degrees Celsius.

Setting up a refrigerated display case allows you to set the required temperature and humidity characteristics and adapt the equipment for storing certain food products with a limited sales period. Errors in shop windows can lead to malfunctions, additional financial costs, product damage and losses. Effective operation of a display refrigerator is a guarantee of keeping goods fresh. Temperature settings are necessary during the initial installation of the equipment, after repairs have been made, in the event of a power outage and program failure.
Refrigeration installation and adjustment
When installing a refrigerated display case, it is important to follow the manufacturer's recommendations, setup instructions, take into account the climatic conditions of operation, the degree of chamber loading, and design features. It is more reasonable to entrust the first setup of the equipment to the experienced specialists of the Avangard Service company, who are familiar with all the technical features and have experience in eliminating errors and malfunctions, installing and maintaining units from different manufacturers. When installing the refrigerator, it is important to pay special attention to temperature control. How to set up a refrigerated display case?
How to choose a temperature regime?
Different food items require special storage temperatures. To find out how to customize the equipment for individual operating conditions, it is recommended that you read the manufacturer's instructions. Refrigerated display cases are a complex installation, the adjustment of which is wiser to entrust to professionals in their field. If you do not understand something, then it is better to contact experienced craftsmen in order to avoid equipment breakdown, since any errors can reset the exposed program.
For storage of meat and fish products, a temperature of minus 2 degrees is required, for confectionery - +7, for vegetables and fruits - +8. The correct temperature and humidity regime protects food from chapping, condensation, ice, loss of freshness and original appearance.
How do I adjust the temperature in my display refrigerator to ensure efficient and trouble-free operation? To set the parameters, you must use the control unit, which is usually located at the bottom of the refrigerator. It is this element that is responsible for regulating the temperature inside the sealed chamber.
In case of failure of the electronic control unit, the cycles of switching on and off the unit are disrupted, which ultimately can lead to food spoilage.
Setting the temperature regime of display refrigerators
Manufacturers carry out the initial setting of the refrigerator at the factory for standard operation. If you need to adjust the temperature inside the display case in accordance with the products stored in it, then it is recommended to use the instructions with which the equipment is supplied to consumers. Setting up the refrigerator should be started by checking the voltage.
Most modern modifications are configured via the remote control, which allows you to set the optimal operating mode. Check with the built-in thermometer if the actual and programmed temperatures match. If you observe discrepancies in the readings, this indicates that the heat exchanger is dirty. This situation can arise due to the formation of ice, condensation, dust and debris. Maintaining cleanliness, maintenance and monthly spring cleaning will help extend equipment life, avoid temperature distortion and product spoilage.
Refrigerated display cases Ariada and a number of other models have an automatic defrosting and drainage system, which facilitates the operation of refrigeration equipment. To service the rest of the modifications, you will need to disconnect them from the power supply and carry out wet cleaning using soda.
If the compressor does not start, the refrigerator works, but does not freeze, the chamber is sweating, then this indicates a malfunction of the refrigerated display case, for the elimination of which it is recommended to contact experienced craftsmen.
Controller programming
Setting up the equipment through the control unit requires certain qualifications and knowledge. Use professional help to program the controller in the refrigerated display case.
This element is responsible for the following parameters:
the frequency of defrosting;
temperature to stop the fan;
defrosting duration;
working temperature and humidity conditions;
defrosting temperature and other nuances.
If the temperature of the display case does not drop to the desired level, then this may indicate a compressor malfunction, refrigerant leakage, icing of the heat exchanger, violations of thermal insulation, low pressure. If the temperature does not drop, it is recommended to disconnect the equipment from the mains for defrosting and cleaning.
Refrigerated display cabinet Polyus Eco is suitable for indoor use in the temperature range from +12 to +25 degrees and humidity not more than 60 percent. Installation and adjustment of this type of equipment is carried out only by qualified craftsmen.
Experienced specialists of the Avangard Service company will provide qualified assistance in the professional setting up of equipment for all types of food products in accordance with the needs of your enterprise and environmental conditions, which will extend the life of the equipment and ensure optimal storage conditions for products.
To ensure the full functionality and high-quality operation of the structure, it is important to understand what temperature should be in refrigeration units. The fact is that various conditions are provided for storing different types of products, in particular:
- sausage, meat, confectionery cream products - from +2 to +6 degrees;
- fish (salted, preserves, cold smoked) - from zero to minus eight degrees.
How to adjust refrigerated display cases
Factory settings, as a rule, do not meet the requirements necessary for each individual case. Unlike other cooling systems, they require adjustment. This factor is associated with the need to place one or another product that requires special conditions. How to set up a refrigerated display case is indicated in the operating instructions, but often there are nuances that distinguish real actions from those described. Based on this, a person who has not previously encountered this type of activity and has no experience is recommended to use the services of professional customizers. If the connection and operating conditions are incorrect, the goods will deteriorate, and the company or store will incur significant losses.
Adjustment usually occurs after installation, connection of equipment and is carried out by setting parameters on the control unit, which in most models is located closer to the bottom of the chamber. If it is damaged, the operating cycles (on / off) are disrupted. Consequently, the regime also gets confused. For adjustment, special panels or remote controls are often used. This is only possible if the system is fully functional.
Before proceeding with the adjustment of the installation, it is necessary to check the voltage level. To avoid surges, it is advisable to install a voltage stabilizer.
