   Detalis：

  Key operation 

· Check parameter set value: 

  Press ▲ and then loosen to display the set upper limit;  Press and then loosen▼to display the.  

 Modify parameter set value

· Press set for more than 3s to cnter into parameter modifying status the last,display the last adjusted 

  menu after electrified with parameter modifying indicator light on.

· Press ▲ or▼to go forward or backward the menu item; press set to display the current.

  Parameter set value

· Press set and ■ or ■ simultaneously can adjust the  current parameter set value;press set and ■

  simultaneously more than 1s will increase current parameter set value quickly; press set and ■ 

   simultaneously more than 1s will decrease current parameter set value puickly;

· Press rst or no key operation in 30s will save the  modified parameter and retutn to normal 

  temperature display status.

  Restore the parameter setting 

· When electrify the controller,first check the  

  parameter setting,if parameter setting is 

  wrong, LED display E1 with buzzer sound,at 

  this time press Set will restore default  

  parameter setting.

· Advise to reset the parameter.

Control output

· Compressor: When the storage temp.Is higher than set  temp.Upper limit,compressor starts,

  lower than set temp. Lower limit,compressor stops, When sensor errir,  compressor works 

  proportionably as on -15 minutes off -30 minutes. After electrified or compressor stops . 

  Compressor restart-up is allowed after running out of compressor protection time.

· Alarm: While temp.exceeding valus is not 0.LED blinkingly displays current temperature

  when storage temperature is higher than set temperature upper limip +exceeding temp 

  value or lower than set lower limit-exceeding temp. value. When rumming out of the 

  exceeding temp.limit alarm delay after electrified. exceeding temp.limit alarm starts 

  with buzzer sound,and alarm cancel when temperature return to normal temperature

  LED blinkingly  Display E1 with buzzer sound when memorizer error; display E2 with 

  buzzer sound when sensor error, Display HH when temp. Higher than 99°C and lower  

  than 120'C. Press any key to cancel alarm sound, but alarm status remains.

Safety regulations

· Danger: Strictly distinguish the sensor down-lead,power wire and output relay interface 

  from one another,prohibit wrong connections or overloading the relay. All connections  

  should be modified under electricity cut-off.

· Warning: Prohibit to use the machine in water or under the environment of ower damp, 

  high temperature,string electromagnetism interference ir string corrosion.

· Caution: The power supply should conform to one labeled on the machine,and ensure 

  the stability of the power voltage.  Sensor down-lead and power should be kept for a  

  proper distance to avoid possible interferences.
