steps:
1. Press the 

 key for more than 1 second, the screen shows the setting temperature;

2. Press the 

 key again and the screen will then show the inner temperature.

•Setting temperature
The  thermostat on  the  control  panel  of  the  low temperature  freezer  can  manually set  the  control 
parameters.
1. Press the 

 key for more than 1 second, the screen shows the setting temperature;

2. Set a new temperature, the screen shows the setting temperature, press the 

 key or 

 key to 

adjust the required temperature;
3. After the setting temperature fi nish, press the 

 key once to save and exit.

•Error display
Suggestion: When it is judged that the temperature probe is wrong, please cut off the power . 

•First,  please check if the connection of the temperature  probe is loose.  If user 
tune out  the internal code  while  adjusting the  thermostat,  wait  one  minute and 
until it shows real temperature inside the cabinet then to operate again, that is to 
avoid the failure of the freezer due to the change of the control parameters.
In the event of a power shutdown or other fault, the freezer stops temporarily and 
the temperature inside the freezer will rise, if it power can not recover in a short 
time,  please consider  taking out the  stored items  for other thermal storage and 
processing, to avoid loss caused by storage damage.
•Before  stored items put into the freezer,  please  confi rm  in  advance  weather it 
is suitable for the low temperature you set, so as to avoid loss from stored items 
damaged due to the unsuitable temperature.
