Modify the parameters set value
○Press set key more than 3 seconds to enter parameters change model, shows that after electrify the last adjustment menu item,At the same time parameter modify mode indicator.
○Press the up or down keys can be move up or down menu item;The parameter setting of the press Set key displays the current menu.
○Press Set key, then press the up or down keys to adjust the current menu parameters Set value;At the same time hold the Set key and the up key for more than 1 second can be quickly raised the parameters setting of the current menu;At the same time hold the Set key and key down for more than 1 second parameter value can be quickly cut the current menu.
○Press Rst or 30 seconds without any key operation, save parameter changes and return to normal temperature display status.
★Manual defrost
○Defrosting time not is set to 0, allow manual defrost
○do not defrosting hold the button down for 3 seconds when the above can manually open defrosting
○Defrost hold the button down for 3 seconds when the above can be stopped manually defrosting
★Recovery parameter Settings
○machine up electricity, you check the parameter setting is correct.If the check to the error, the display E1, at the same time a buzzer sounded.Press Set key at this time will restore the default parameter Settings and work normally, suggest to reset parameters at this time.

Output control
Compressor:
○Library temperature higher than the set limit on the temperature of the compressor open, lower than the set time limit under the temperature of compressor shut down.Library temperature sensor fault compressor according to the open 15 minutes after the proportion of 30 minutes, stop running.Machine or compressor shut down after running 3 minutes after the power supply of compressor protection time to allow the compressor to open again.
Defrost:
○Machine run Settings or defrost defrost cycle more than hold down the button for 3 seconds defrosting, defrosting is prohibited during the refrigeration output.Depleted or defrosting defrosting time hold down the button more than 3 seconds defrosting end.Machine electricity or thawed after re-run the defrost cycle.Defrost cycle or any of the defrosting time is set to 0 to eliminate timing defrost function, but when to allow manual defrost defrost time is not zero.
warning:
○Temperature overrun deviation is not 0, the library temperature higher than the set temperature limit + deviation or below the set temperature overrun occurs when the temperature of the lower limit temperature overrun deviation transfinite alarm temperature, the flashing display the current temperature and the buzzer sounded.Cancel the alarm temperature back to normal after the temperature range.
○Storage failure flashing display E1 and the buzzer rang;Sensor fault show flashing E2 and buzzer ringing;Temperature higher than 99 ºC and below 120 ºC show HH.Alarm when press any key to manually, but does not change the state of alarm display.

★Safety rules
○dangerous
1.Strictly distinguish between the sensing lines, power cord, and the output relay interface, can not be wrong, relay always over load
2.All wiring changes must be conducted under the condition of the power off
○warning
This machine is prohibited in the water or damp environment use, banned in high temperature, strong electromagnetic interference, strong corrosive environment;
○Pay attention to
1.The power supply voltage should be consistent with the voltage marked on the machine, and ensure the stability of the power supply voltage
2.To avoid possible interference, it is recommended that the sensor lead keep proper distance with power lines
