5.1 Front Panel Controls

• PV Display: Shows the current measured temperature value.
• SV Display: Shows the set temperature value.
• SET Key: Used to enter parameter setting mode and confirm selections.
• Left Key (<): Used to move the cursor or select digits during parameter setting.
• Increase Key (∧): Used to increase the value of a parameter.
• Reduce Key (∨): Used to decrease the value of a parameter.
• Indicator Lights: LEDs for AT (Auto-tuning), A/M (Auto/Manual), AL1/AL2 (Alarms), OUT1/OUT2 (Outputs).

5.2 Basic Temperature Setting

1. Press the SET key once. The SV display will start flashing.
2. Use the ∧ (Increase) and ∨ (Reduce) keys to adjust the desired set temperature. Use the < (Left) key to move between digits for faster adjustment.
3. Press the SET key again to confirm the new set value and exit the setting mode.

5.3 Advanced Parameter Settings

To access advanced parameters (e.g., input type, control mode, alarm settings, PID parameters), press and hold the SET key for several seconds until the parameter code appears on the PV display. Use the ∧ and ∨ keys to navigate through parameters and adjust their values. Refer to the full electronic manual (scan QR code on product label) for a complete list of parameters and their functions.

6. Maintenance

The JDOUNFMO TC5-L temperature controller is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure its longevity:

• Cleaning: Periodically wipe the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off before cleaning.
• Environmental Conditions: Operate the controller within the specified ambient temperature and humidity ranges to prevent damage. Avoid exposure to direct sunlight, excessive dust, moisture, or corrosive gases.
• Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to erratic behavior or damage.
• Ventilation: Ensure adequate ventilation around the unit to prevent overheating, especially if mounted in an enclosure.
