Key Functions and operation instructions:

Check parameters setting value (in the state of non-settingPress & key it display the set value; Press Downkey itdisplay the set value, Press "Set" it display defrostcycle; Press "Rst" key it display defrost time 
To modify the parameter setting mode:

Press "Set" for 3s to enter the parameter adjusting mode,and set indicator light on LED displays the parametersadjusted last time
Press &or7 to choose desired parameters. After theselection of parameters the value of correspondingparameter is displayed by pressing “Set"

Press Set and &orT simultaneously to adjust the valueof parameters Press "Set", and hold on &ory for morethan 1 second to quickly increase or decrease the parametervalue Press &orT to alter other parameters after the settingof one parameter value.Just repeat the above-mentionedsteps.
System will save the modified parameter value and back tthe normal working status if pressing the "Rst* key or no keyoperations in 30s.
Manual defrosting:

Manual defrosting is allowed when defrosting time valueis not set as “0".
Under nondefrosting status, press  key for 3s to startup the manual defrost.
Under defrosting status, press T key for 3s to stopdefrosting.

To restore parameter setting

Firstly, controler checks the parameter setting whenelectrified.Screen display"E1" when finding error, andbuzzer alarm, then Press the “Set" key to restore thedefault value, and system works normally, it is advised toreset the parameter value in such cases.

Control output:
Compressor:
Compressor starts up when measuring temperature ishigher than the setting max. temperature value, andcompressor close when the measuring temperature is lowerthan setting min.temperature value. Compressor worksfollowing the cyde as when probe fails: works for 15 minutesand then stops for 30 minutes. After electrified or compressorstops,compressor restart-up is allowed after running out ofcompressor protection time.
Defrosting:
Defrosting starts in any of the following status:Controller runs out of the setting defrosting cycle.Under the non-defrosting mode, pressing the key formore than 3 seconds.
Note: Refrigerating output is forbidden during the defrostingp1oCeSS。
Defrosting stops in any of the following status:Defrosting time is run out of.
Under the defrosting mode, pressing the Downkey for morethan 3 seconds.Another defrosting cycle run again when electrified or whenthe defrosting time used up. Defrosting function is canceledwhen defrosting cyde or defrosting time is set as 0.Manualdefrosting is allowed when defrosting time is not set as 0.Alarm:
Exceeding temperature limit alarm:When sensor measuring value is higher than maximumvalue + set alarming temperature value or lower thanminimum value -set alarming temperature value,temperature controller alarms, buzzer works and LED blinks.Alarm will continue until temperature back to normal range.Screen flashes and displays E1 with buzzer alarms if erroroccurs during storage process, Screen flashes and displaysE2 with buzzer alarms when sensor error;
LED displays "HH" when measuring temperature is between
+99℃ and 120℃.
Note: Pressing any key can manually cancel the alarm sound,while alarm indicator light display status doesn't change.

Safety rule:

Danger:Please strictly distinguish the connections of relay,sensor and power, Make sure the relay is not overload.All the wire connection must be operated under thepower off status.
Warning:
Prohibit to use the controller under the circumstancessuch as :over moisture, over high temperature, strongelectromagnetic interference, strong corrosion.

Notice:Make sure the voltage confirm to the marking on themachine and the power supply steady.It is advised to keep proper distance between sensorleads and power supply wire to avoid possibleinterference.
