3 Technical Descriptions
Single-compressor cooling system
On the basis of temperature checking with sensor in fridge compartment and temperature in freezer
compartment, the request for switch-on/off of compressor and Fan Motor is set /deleted
Compressor operation
In normal mode of operation the compressor functions with the frequency which is prescribed with regard to the
actual conditions of regulations.
The condition for compressor switch-on is not considered if the compressor is locked due to min switch-off time
which is 5 minutes
The same is valid for compressor switch-off, when the compressor does not switch off until the min switch-on
time is reached which is 5 minutes.
PC Damper operation
The PC Damper can be opened only to the extreme position, or completely closed.
At switching-on it is necessary to set the PC Damper, so that it can be opened and closed. It is reset when the
parameter “max time of PC Damper position” which is 6 hours, expires. This time is considered when the PC Damper is in one
position, open or closed.
It is not possible to set the PC Damper during defrosting.
Whenever the PC Damper opens, the Fan Motor starts to function.
When the PC Damper is closed, the Fan Motor operates according to its regulation.
Opening or closing any door does not affect the PC Damper operation.
Fan Motor operation
The Fan Motor switches on when the request is made for cooling of fridge or freezer compartment. When a request
is made for cooling of fridge compartment, first the PC Damper opens and after 30 seconds, the Fan Motor switches on.
Fan Motor switches on with time delay after the compressor start-up - depending on the last
cycle.
If the last cycle was a normal cycle, the Fan Motor switches on immediately.
After defrosting of the evaporator, the Fan Motor starts to function after 4 minutes.
Fan Motor operation is suspended if the freezer or refrigerator door is opened.
When the door is closed, the Fan Motor switches-on after 5 seconds.
If the door is open for 20 minutes, normal operation of Fan Motor continues as prescribed by regulation of cooling.
LED Lamp
Fridge compartment LED Lamp switches on when the door opens.
Fridge compartment LED Lamp switches off when the door closes.
In case of open door, the incorporated time limitation becomes active which switches off the LED Lamp after
10 minutes
Condition for cooling of fridge compartment (PC)
The temperature in fridge compartment can be set from +1 to +9 °C.
Based on the verification of the temperature in fridge compartment, the request for cooling of fridge
compartment is set or deleted.
When the temperature in fridge compartment is equal to or rises above +1 °C, the PC Damper opens and after 30
seconds (Fan Motor switch-on delay time due to PC Damper switch-on) the Fan Motor in freezer compartment switches on, too.
When the temperature in fridge compartment is lower than +1 °C, the PC Damper closes, and in case the request for
cooling of freezer compartment is not set, the Fan Motor in freezer compartment switches off.
On the basis of request for cooling of fridge compartment, the PC Damper and Fan Motor in the freezer compartment switch on.

Condition for fridge of freezer compartment (FC)
Standard compressor
The temperature in freezer compartment can be set from -16°C to -24°C.
It operates according to the principle of setting/deleting the request for cooling of freezer compartment.
When the temperature in the freezer compartment is equal to or rises above +1 ° C, the compressor and Fan Motor
(in normal operation) switch on or, after the expiry of Fan Motor switch-on delay time after defrosting, the Fan Motor of
freezer compartment switches on, too.
When the temperature in freezer compartment is lower than 0 ° C, the request for cooling of freezer
compartment is deleted; the compressor and Fan Motor of freezer compartment switch off.
Based on request for cooling of freezer compartment the compressor and Fan Motor of freezer compartment are
controlled.
Defrosting
Unconditional start of defrosting is installed in the following cases:
1. At switch-on of "Fast Freeze" function if the compressor of freezer compartment does not function.
2. At switch-on of "Super Cool" function if the compressor of freezer compartment does not function.
3. At switch-on of "Extreme Freeze" function if the compressor of freezer compartment does not function
4. If, at switch on of "Fast Freeze" or "Super Cool" function the compressor functions without interruption for 1
hour i.e. immediately after the first interruption of operation of compressor.
5. Always after the terminated "Super Cool", "Extreme Freeze" and "Fast Freeze" function.
6. In case when the user interrupts the "Fast Freeze" function later than in 8 h after switching-on this function.
