1. ‌Boot Preparation。
   • Turn on the power and the controller will display the current temperature (such as “InP” or measured value) when powered on
   • Place the items to be dried evenly on the shelves, ensure a spacing of ≥5cm to ensure smooth airflow, and a single layer load ≤ 10kgTurn on the power and the controller will display the current temperature (such as “InP” or measured value) when powered onPlace the items to be dried evenly on the shelves, ensure a spacing of ≥5cm to ensure smooth airflow, and a single layer load ≤ 10kg
2. ‌Set the temperature。
   • Click the “Set” button to enter the temperature setting mode, the lower row of the display window displays “SP”, and the upper row displays the current set value (single digit flashing)。‌‌
   • Adjust with the following buttons：
     1. ‌Shift key: Move the cursor to the number of bits to be modified (e.g., ten digits, single digits).
     2. Increase/decrease key: Adjust the value (long press to increase or decrease continuously).Shift key: Move the cursor to the number of bits to be modified (e.g., ten digits, single digits).Increase/decrease key: Adjust the value (long press to increase or decrease continuously).
   • After confirming the target temperature, click the “set” button again to save (automatic saving within 1 minute)。‌‌
   • ‌Set the time (only for devices with timer function).
     • After saving the temperature, click the “Set” button again to enter the time setting mode, the lower row of the display window displays “ST”, and the upper row displays the current set value (single digit flashing).
     • Use the shift, increase, and decrease keys to adjust the time (unit: minutes), and set it to “0” to indicate that there is no timer function
     • Click the “Settings” key to save and exitWhen the set temperature is reached, the timer starts counting down (when the time is not 0), and at the end the buzzer alarms and shows “End”
3. ‌Activation and monitoring。Preheat for 30–60 minutes for first use (e.g. 45 minutes at 150°C).
4. Turn off the power supply and cool to room temperature before picking up to prevent burns
5. When an over-temperature alarm is detected (the “ALM” light is on), immediately check the sensor or power supply
   • The device automatically heats up, and the lower row of the display window shows the temperature or remaining time in real time
   • When the set temperature is reached, the timer starts counting down (when the time is not 0), and at the end the buzzer alarms and shows “End”

Key considerations

1. ‌Temperature range: 50–100°C is recommended for regular materials, avoid exceeding 300°C to prevent damage to items or equipment
2. ‌Devices with no timer function: Skip the time setting step, and the device will continue to run until it stops manually
3. ‌Safe operation：
   • Preheat for 30–60 minutes for first use (e.g. 45 minutes at 150°C).
   • Turn off the power supply and cool to room temperature before picking up to prevent burns
