Third, the panel operation

1. Control temperature setting: press key to display the shutdown temperature, press key to change the control temperature, without pressing any key, return to display the warehouse temperature and save the parameters. (First power on, press the key to skip the press delay)
2. Parameter setting: press the key for six seconds before entering the setting program, that is, E1 will be displayed.
   Press the key to select the menu for setting E1-P1 and other parameters. Press to enter the corresponding parameters. If no key is pressed within six seconds, the normal operation mode will be returned.
3. Parameter locking: lONg press to show “OFF” for locking and “on” for unlocking. Indicates that it is currently locked. If you need to adjust the parameters, unlock them first and then adjust them.
4. Modify the factory setting value: press to enter the temperature setting interface, adjust the control temperature, and after exiting the display state, press for a long time to enter the parameter setting interface and adjust the parameters, and then press to display any characters of E1 ~ P1, and press for six seconds to display “COP”, and store the modified control temperature and parameter setting value as the current factory setting value.
5. On/off function: press and hold the key for 6 seconds to realize the off function, and the display screen will display “-“and turn off other output states except lighting;
6. Restore the factory settings: In the power-off state, press and hold the key for 6 seconds, and “888” will be displayed, indicating that the factory settings are successfully restored. Note: If it is unlocked, unlock it first.
7. Refrigeration indicator light: During refrigeration, the refrigeration indicator light is on; The constant temperature refrigeration indicator goes out; During the delay, the indicator light flashes.
   Lighting indicator: During the lighting work, the lighting indicator lights up and turns off when it is turned off.
   Fan indicator light: During the operation of the fan, the fan indicator light is on, and it goes out when it is turned off.
8. Lighting indicator: Press the key to start or stop lighting.
9. Defrosting indicator: You can enter or exit the defrosting state by pressing the defrosting button for six seconds.

Program list

Function Description

• Temperature control: refrigeration: when the current temperature is more than or equal to the set temperature+ temperature back difference and delayed, the load relay will pull in. Refrigeration stop: when the current temperature is less than or equal to the set temperature, the load relay is disconnected.
• Defrosting function:
  When the set time reaches the shutdown defrosting interval (F2), enter the shutdown defrosting function to stop the current compressor; When the defrosting time (F1) is met, the shutdown defrosting mode is exited, and the compressor is started in a delayed mode, and the refrigeration operation mode is entered.
  Lock the display of warehouse temperature during defrosting: when F3=01 is locked, lock the temperature in the warehouse during defrosting and display the temperature at the beginning of defrosting. After defrosting, unlock and resume displaying the normal probe temperature.
• Fan control: the fan runs according to the set value of parameter (H1). When the fan is synchronized with the compressor, it will take 3 seconds to start the fan after the compressor starts.
• Fault running time: When the temperature sensor fails, the compressor stops for 15 minutes
  and runs for 15 minutes.

• Alarm mode:
  High temperature alarm: When the probe temperature is ≥C1, the display of “HHH” flashes alternately with the current temperature, and pressing any key can eliminate the alarm sound. Low temperature alarm: When the prob e temperature is ≤C2, the display “LLL” flashes alternately with the current temperature, and pressing any key c an eliminate the alarm sound. The probe shows E-1 for short circuit, and “E-2” for open circuit or overrun.

Six, wiring diagram

Note:

1. The thermostat can’t be installed where there is dripping water.
2. The probe should be installed with the head up and the line down.
3. In order to prevent high-frequency dry burning, the probe wire should not be tied in parallel with the power cord, but should be wired separately
