3．“alarm” indicator：it is on if temperature is abnormal or over-temperature alarm, or it is off
4．“defrost” indicator：when the evaporator defrosts, the dictator is on.
5．“UV lighting” indicator：it is on when sterilisation is on, or it is off
6．“set temp.” indicator：it is on if the right screen displays set temperature, or it is off
7．“set time” indicator：it is on if right screen displays running time, or it is off
8．“set”key：set or view temperature ,time and other parameters
9．“◄”shift key：press this key to modify set value in setting mode
10．“▼”decrease / rerun：press this key to decrease set value in setting mode, long press this key decrease continuously. After running is over, in non-setting mode, long press this key to reboot.
11．“▲”increase：increase set value in setting value, long press this key increase continuously
12．“UV”key： button for sterilisation

8. Operation

1．After power is connected, left screen displays “index number and version number”, right screen displays “the max setting temperature” . It will access normal mode after 3 seconds

2．View and set temperature and time of constant temperature

1）if without timing function
Press “set” key to access temperature setting mode, left screen displays “SP” right screen displays setting temperature(it will flash from single digit), modify required setting value via shift ,increase or decrease key; re-press “set” key to log out this mode, the modified data will be saved automatically.

2）if with timing function
Press “set” key to access temperature setting mode, left screen displays “SP” right screen displays setting temperature (it will flash from single digit), modify required setting value via shift ,increase or decrease key; re-press “set” to access timing setting mode , left screen displays “ST”, right screen displays timing time (it will flash from single digit);re-press “set” key to log out this setting mode, the modified data will be saved automatically.
When timing is “0”, it means no timing function, the controller keeps running, right screen displays setting temperature; when timing time is not “0”, right screen displays running time or setting temperature. If display running time, the decimal point of the single digit which is on the right screen is on, when measured temperature reaches setting temperature, the timer start timing, the decimal point of the single digit which is on the right screen is flashing, timing time is over and stop running, the right screen displays “End”, beeper beeps, it will stop beeping after 1 minute. After running is over, long press “decrease” key for 3 seconds to reboot
Notice : if change setting temperature during timing, the controller will start timing from 0.

3. Sensor alarms abnormally
If the left screen displays “---“, it means that there is something wrong with temperature sensor or controller or temperature is in outside of temperature range, controller will disconnect heating output automatically, beeper beeps, alarm indicator is on, please check the temperature sensor and other connections.

4．When oven-temperature alarming, beeper beeps, “ALM” is on. if oven-temperature alarm because of setting temperature changed, “ALM” is off and without beep
5．Press any key to mute if beeper beeps

6．Without press any key within 1 minute in setting mode, it will be back to normal mode automatically.

9. View and set intrinsic parameters

Long press the set key for 3 seconds, the left screen displays “Lc”, the right screen displays password, you can modify the required value via “increase” “ decrease” or “shift” key . re-press the “set” key , if the password is incorrect, the controller will be back to normal mode, if the password is correct, it will access the temperature setting mode. re-press “set” key to modify parameters of . long re-press “set” key for 3 seconds to log out this mode, the data will be saved automatically.

8．In order to make sure good temperature effect, don’t touch or collide the temperature sensor
10.This equipment is equipped with a cooling relief function, which is an intermittent cooling mode. When cooling stops, it is normal that if there is pull-in of magnet valve or refrigerant backflow sound

11. Troubleshooting

Troubleshooting	Handing
Screen displays (----)	·There is something wrong with temperature sensor , check the temperature sensor , model : ;2400302;
Temperature can’t reach setting value	·Setting temperature is lower than display temperature Check whether the heater is damaged Check the controller board and other connections
Temperature rises slowly	Check whether the fan stops working fan is broken something wrong with relative connections
Screen displays nothing	check whether power switch is on check whether the plug cord is 220V check failures according to wiring layout
