as follows:
Press digit switch key to change the flashing digit, press temperature adjustment key to change
current digit value;
Press setting key when adjusting to required temperature, change and save parameters.
The setting temperature by default of cold storage area is 5°C, the frozen area is -40°C;
For non-use setting, the default value is 1, meaning the normal operation of current activated area,
0 means the current activated area is disabled;
Voltage and environment temperature can only be inquired, but can't be set .
High-low temperature alarm value can be set within the following range:
The highest setting temperature+5°C≥high temperature alarm value≥setting temperature+5°C
The lowest setting temperature-5°C≤low temperature alarm value≤setting temperature-5°C
The “├” in front of figure represents “+”.
② Start delay setting
In unlock status, press setting key and temperature adjustment key for 5s, the display screen
activated by default will show the delay time of current area compressor, then the temperature
area can be changed by temperature area switch;
