• Introduction to code and features
  • PO: Set the start temperature
    • Press the Setup button to enter the internal menu
    • The default display is PO
    • Press the Setup button again to set the required start temperature with the up and down buttons
  • P1: Set the stop temperature
    • Press the Setup button to enter the internal menu
    • The display is P0, switch to P1 with the up and down keys
    • Press the Setup button again to set the required stop temperature with the up and down buttons
  • P2: Set the temperature correction
    • Press the Setup button to enter the internal menu
    • Switch to P2 by pressing the up and down buttons
    • Press the Setup button again to set the required calibration temperature with the up and down buttons
    • Note: The calibration temperature is the difference between the detected temperature and the actual temperature
      • For example, if the detected temperature is 0.5C higher than the actual temperature, the calibration temperature is -0.5C
      • The formula is: detected temperature + calibration temperature = actual temperature
  • P3: Set the delay start
    • Press the Setup button to enter the internal menu
    • Switch to P3 by pressing the up and down buttons
    • Press the Setup button again to set the required delay time with the up and down buttons
    • The unit is a minute
    • Note: The delay start is used for compressor refrigeration
      • If it is used in a refrigerator freezer, this value needs to be set according to the compressor back pressure
      • The general setting is 3-6 minutes
      • If you are not using it for control or no delay function is required, skip it directly
  • Note: The appearance of the product may vary depending on the production lot, but the performance is the same.
