P0 Start temperature setting: Press the setting button once to enter the internal menu, the default is P0. Press the setting button again, and set the desired start temperature with the up and down buttons. P1 Stop temperature setting: Press the setting button once to enter the internal menu. The digital display is P0, and to switch to P1 with the up and down buttons. Press the setting button again to set the desired stop temperature with the up and down buttons.
P2 setting temperature correction:
Enter the internal menu, to switch to P2 use the up and down buttons, press the setting button again, and set the required calibration temperature with the up and down buttons. In the setting, if the detected temperature v is 0.5 degrees Celsius higher than the actual temperature v, the calibration temperature that needs to be set is -0.5 degrees Celsius. If the detected temperature v is 1°C lower than the actual temperature v, the calibration temperature to be set is 1°C
Detected temperature ± corrected temperature = actual temperature P3 Start delay setting: Enter the internal menu, use the up and down buttons to move to P3, press the setting button again, and set the desired delay time (in minutes) using the up and down buttons
Delayed start is usually used for compressor cooling. If it is used for refrigerators and freezers, the time should be set to 3-6 minutes depending on the compressor return pressure. (If you do not use compressor control or do not need the delay function, skip this option directly) Heating mode: Start temperature < Stop temperature (the program automatically determines that the working mode is heating mode) Setting method:
Press the settings button to enter the internal menu, set the start temperature through P0 v, and the stop temperature through P1 v Use case: Control the water heater, stop heating at 50 ℃, and start heating again when the temperature returns to 40 ℃. How to set it? 1. Make sure the working mode is heating mode, and the start temperature is lower than the stop temperature
2. Press the settings button to enter the internal menu, select P0 to start the temperature, and set P0 v to 40 ℃ 3. Press the settings button to enter the internal menu, select P1 to stop the temperature setting, and set P1 v to 50 ℃

Cooling mode: Start temperature>Stop temperature (the program automatically determines that the working mode is cooling mode) Setting method: Press the settings button to enter the internal menu, set the start temperature through P0 v, and the stop temperature through P1 v Use case: Control cabinet with heat sink, stop cooling at 26℃, and restart the heat sink when the temperature rises to 30℃. How to set it?
1. Make sure the working mode is cooling mode, and start temperature > stop temperature Use case: Control cabinet with heat sink, stop cooling at 26℃, and restart the heat sink when the temperature rises to 30℃. How to set it? 1. Make sure the working mode is cooling mode, and start temperature > stop temperature 2. Press the setting button to enter the internal menu, select P0 to start the temperature, and set P0 v to 30 ℃
3. Press the setting button to enter the internal menu, select P1 to stop the temperature setting, and set P1 v to 26 ℃

Example of using the settings scenario: How do I adjust the temperature for hatching chicks between 37.5°C and 38°C? 1. Short press the setting key to display P0 on the screen, then short press the setting key to display the current starting temperature. Press the up/down keys to adjust the starting temperature to 37.5℃ (if no operation is performed for 5 seconds, it will be automatically saved and exited) 2. Short press the settings button to display P0 on the screen, press the up button to switch to P1, and then short press the settings button to display the current stop temperature. Press the up/down button to adjust the stop temperature to 38℃ 3. After setting, the temperature controller will control the heating equipment at 37.5℃ for heating. When the temperature rises to 38℃, it will stop, and when the temperature drops to 37.5℃, it will start heating again and continue the cycle
The actual measured temperature is 35℃, and the temperature controller displays 35.6℃. How to calibrate? 1. Short press the settings button to display P0 on the screen, press the increase button to switch to P2, and then press the settings button to display the current temperature calibration. Press the increase/decrease button to adjust the calibration to 0.6℃ (the temperature displayed by the temperature controller is 0.6℃ higher than the actual measured temperature)
