4.1.5 Temperature compensation setting method :
In the power-on state, press and hold the " UP " and " DOWN " keys at the same
time 2 seconds, enter the temperature compensation setting, short press the " SET
" key, you can F1/F2/F3 three parameters switch, short press under the
corresponding parameter " UP " or " DOWN " to compensate temperature
setting, it will automatically
return to standby state:
Compensation temperature
setting range: 10 ℃ ~-10 ℃.

4.2 show
4.2.1When the system is powered on , the display is fully lit 2 seconds , and then enter
the normal display;
4.2.2system is in standby state , the display screen has no display; when the setting
is adjusted in the standby state, the corresponding function of the display screen
lights up;
4.2.3In the state of key setting, the corresponding function font on the digital screen
lights up;
4.2.4The temperature is displayed on the digital screen
4.2.5The nixie tube font is bright white .
4.2.6When entering the corresponding parameter setting, the current value will be
displayed and flashing, and the setting will be saved after no operation flashes
for five seconds.
4.2.7The flicker frequency is 2Hz .
5. System Control (Operation Mode Definition)
5.1 Compressor speed :
 Compressor speed MAX: 3200r/min, ECO: 2000r/min;
 When the power is turned on or turned on for the first time , the compressor will 2000 turn
run, 2 After a few minutes, it will switch to the set cooling mode operation;
5.2 compressor control
 Boot condition: the actual temperature in the box ≥ Tk ;
 Stop condition: the actual temperature in the box ≤ Tt ;
 Maintain the current state: Tt < actual temperature in the box < Tk .
6. fault display
When the refrigerator fails, the display shows the failure mode, as shown in the
following table:
code error type
E1 Low battery voltage protection (module input voltage is lower than the set value)
E2 Fan short circuit protection (fan load current greater than 1A)
E3 Compressor fault protection (motor stall or refrigeration system overpressure)
E4
The compressor motor speed is too low (the refrigeration system is overloaded, the
motor cannot maintain the minimum speed of 1850r/min)
E5 Compressor control module over temperature protection
E6 Thermal head failure (compressor and fan stop)
