Settable Parameters:
* P0: Start Temperature (Range -50 to 110℃. Default 25℃)
* P1: Stop Temperature (Range -50 to 110℃. Default 40℃)
* P2: Temperature Calibration (Range -10 to 10℃. Default 0℃)
* P3: Delay Start (Range 0-10 minutes. Default 0 minutes)

Code and Function Introduction:
* P0: Set Start Temperature. Press the SET button to enter the internal menu. The default display is for P0, and then click the SET button, use up and down buttons to set the starting temperature.
* P1: Set Stop Temperature. Press the SET button to enter the internal menu. The default display is for P0. Use up and down button to change to P1, and then press the SET button again, use up and down buttons to set the stop temperature.
* P2: Set Temperature Calibration. Press the SET button to enter the internal menu. Use up and down buttons to change to P2, press the SET button again, use the up and down button to do the calibration. (Attention: In the settings, if the detected temperature value is 0.5°C higher than the actual temperature, the calibration temperature to be set is -0.5°C. If the detected value is 1°C lower than the actual temperature value, the calibration temperature to be set is 1°C. Detected temperature + corrected temperature = actual temperature.)
* P3: Set Delay Start. Press the SET button to enter the internal menu. Switch to P3 by pressing the up and down buttons. Press the SET button again, and set the required delay time by pressing the up and down buttons, and the unit is minutes. (Attention: Delay start is generally used for compressor refrigeration. If it is used for refrigerator freezers, this value needs to be set. According to the compressor return pressure, the general setting value is 3-6 minutes. If you are not using it for control or don't need the delay function, you can skip it.

FAQ:
1. How to restore factory settings?
It is powered on, press and hold the up and down buttons at the same time for about 3 seconds, after the digital tube displays 888, it will automatically jump to the detection temperature, that is, the factory settings are restored successfully.

2. Its digital tube displays LLL.
It means that the sensor is open, check the sensor, or replace the sensor.

3. It displays HHH.
It means that the sensor is short-circuited.
