Intelligent Digital Temperature Controller Switch Digital Display Controller Features: 1. Set the starting temperature: press the setting key once to enter the internal menu. The default display is P0. Press the setting key again to set the required starting temperature through the up and down keys. 2. Set the stop temperature: press the setting key once to enter the internal menu. The digital display is PO. Switch to P1 through the up and down keys, press the setting key again, and set the required stop temperature through the up and down keys. 3. Set temperature correction: enter the internal menu in the same way, switch to P2 through the up and down keys, press the setting key again, and set the required calibration temperature through the up and down keys. During setting, if the detected temperature value is 0.5 ℃ higher than the actual temperature value, the calibration temperature to be set is - 0.5 ℃. If the detected temperature value is 1 ℃ lower than the actual temperature value, the calibration temperature to be set is 1 ℃. Detection temperature=correction temperature=actual temperature. 4. Set delay start: enter the internal menu in the same way, switch to P3 through up and down keys, press the setting key again, and set the required delay time (unit: minutes) through up and down keys. Delayed start is generally used for compressor refrigeration. If it is used for refrigerator freezer, this value needs to be set. The general setting value is 3-6 minutes according to the compressor back pressure. If you are not used to control the compressor or do not need the delay function, skip this item directly 5. Start temperature ＜ stop temperature=heating mode, start temperature ＞ stop temperature=cooling mode.
