Parameter code	Parameter name	range	Factory set	illustration
1	Low limit	-50℃～49.5℃	-15℃	The compressor shut down
2	Upper limit	-49.5℃～50℃	-10℃	Compressor open
3	Spacing interval of defrosting	0～99h	5h	timer mode:Total working time of the compressor
4	defrosting time	10～99m	30m	-
5	the temperature of stopping the  defrosting	4℃～30℃	15℃	reach the temperature,the frost will be shut down
6	Power up Delay	30s～360s	60s	-
7	Time delay after the  defrosting	4m～99m	5m	-
8	temperature correction	-5℃～5℃	00℃	-
P	After the sensor damaged,the time for compressor working	10～100m	15m	-
L	After the sensor damaged,the pause interval for compressor stop working	20～180m	30m	-

Save Preferences:Without any operation, keep for 10 seconds,the system will automatically save the parameters.

Manual refrigeration：After controller power on again,hold the “▲”button for 3seconds,The controller will open the compressor.

 
Manual Defrosting：hold the “Manual defrost”button for 3 seconds，controller will begin to frost；at this time,hold the “Manual defrost”button for 3 seconds again, defrosting will be stopped.
 
Interface display：

Code	Illustration	operation
F	The temperature of refrigeration sensor	-
H	The temperature of  defrosting sensor	Refrigeration,press the “Manual defrost”button，The screen will display  the temperature of stopping the  defrosting.
E	remaining time Of  defrosting	Defrosting,press the “Manual defrost”button，The screen will display remaining time of defrosting.

 
Fault indication
1、C-CCC：Temperature sensor is damaged，now controller will use Defrosting sensor acquiescently, in order to ensure that the compressor normal operation
2、H-HHH：Defrosting sensor is damaged，now controller will use Temperature sensor acquiescently, in order to ensure that the Defrosting  normal operation。
Hole Size：113mm（wide）×45mm（high）
Notes:
The sensor and the power line is not in the same pipeline.
