3.1.

Connecting of the appliance and management

When you first start the machine the temperature must be set to a setting at +5 °C. After the refrigerator is plugged in, it begins to
operate in accordance with the conditions of temperature regulation. In the case that the power-on temperature sensor on the evap-
orator of the cooling part of less than +10 °C, the compressor is blocked for a minimum off time of the compressor, which is 5 min-
utes. 

Operation

Logic board display

Adjustment and display of temperatures of the cooling / freezer:

By pressing the "A" round temperature is set from left to right. Each time you press, the setting moves one step. On module 6 LEDs,
which signaled the set temperature and the function of intense freezing. LED1 representing setting intense freezing, LED2 repre-
senting s1 °C, LED3 +3 °C and that when further to LED6, which represents a last adju9 °C.
The first time you press the button, starts with a frequency of 1 Hz flashes last temperature setting. The next time we move one step
and starts flashing the new temperature setting. After 3 seconds, the new setting is saved and the flashing stops.
Function of intense freezing incorporated by pressing "A" repeatedly to light up the symbol "C". After 50 hours, the function is auto-
matically terminated and the setting returns to the last selected setting that was before activating the intense freezing. Feature
intense freezing can also prematurely terminated if another setting is selected.

Purpose of regulation, input parameters and controlled outputs

Purpose of regulation

Basic functionality of the appliance

The purpose of the electronics can be divided into several completed jobs:

• Assurance of the set temperature in cooling compartment
• Melting ice in the cooling compartment

Set temperature in cooling compartment is adjustable in increments of temperature, 1, +3, +5, +7, +9 °C. Supported func-
tion is intense freezing food (Super Cool Mode).

Input parameters

1. The measured temperature at the sensor of the cooling space.
2. The measured temperature at the sensor of the evaporator of the cooling space
3. Magnetic switches on doors and refrigeration space
4. Settings through the control module

Controlled outputs

1. Compressor
2. Fan
3. Cooling compartment illumination
5. Display
