B - Defrosting
1. If additional defrosting is necessary in result of difficult conditions of operation and the SF function is
switched off (c4=0), the button
should be pressed. Then the green diode will light permanently on the
button and ‘dF’ will appear on the display instead of measurement of temperature. This moment the
unit will begin a defrosting cycle.
2. If defrosting take place and parameter r2=1 then time od defrosting is controlled by parameter ‘c1’. If
defrosting takes place and parameter r2=0 and temperature on evaporator is higher than temperature set in
parameter ‘d2’, after about 10 seconds the unit will begin the end phase of defrosting and after its end it will
start further operation. If defrosting take place and parameter r2=0 and temperature on evaporator is lower
than temperature set in parameter ‘d2’ than GC201 will turn on the defrost mode and after reaching the
temperature from the parameter 'd2' will enter the end of defrosting procedure (this state is signaled by
blinking green LED on the button ) consisting of one dripping phase in which the compressor remains
off for the time specified by parameter 'c3'.
If the time of entering to automatic defrosting mode (time c0) take place during the compressor operation,
the defrost mode will be delayed until the compressor is turned off.
The compressor can be switched off when the set chamber temperature is reached (according to the control
hysteresis) or after exceeding the maximum compressor operation time (for c5 ≠ 0).
If the device cannot reach the set temperature, the maximum compressor operation time in parameter c5
should be extended.
3. If defrosting takes place and temperature on evaporator is lower than temperature set in parameter ‘d2’,
GC201 will switch on defrosting and when temperature in parameter ‘d2’ is reached, the procedure of the
end of defrosting will begin (signalled by a flash of the green diode on the button
) consisting of one
dripping phase in which the compressor is off for time defined by parameter ‘c3’.
4. When ‘dF’ disappears and defrosting is finished, the display shows the temperature that was memorised just
before the beginning of defrosting for the whole time defined in parameter ‘c7’: this is to prevent
complaints because of ‘sudden changes of temperature in the unit’.
5. The unit functions in the same way during manual and automatic defrosting.
C – Super Frost
The function is used to quickly freeze products in the refrigerator. The 'c4' parameter defines the
operating time of the refrigerator in SuperFrost mode (time of continuous compressor operation). It is possible
to set the working time from 1-48h in intervals of 1h. If the parameter c4 is set to "0" then the SF function is
blocked.
If the SF function is blocked, the SF button performs the manual defrost function "dF".
After activating the SuperFrost function, the symbol "SF" appears alternately with the current
temperature preview. The dot on the right side of the display indicates the operation of the compressor.
Continuous lighting - the compressor is working. The dot flashes - waiting for the compressor to start (the
compressor has to work but the minimum compressor standstill condition has not been met). After all the
