5. Setup and Wiring

Before connecting, ensure the power supply is disconnected. The W3103 supports DC12V, DC24V, or AC220V input. Select the appropriate model for your power source.

5.1 Wiring Diagram (DC12V/24V Example)

Wiring diagram for DC12V/24V power supply. Input terminals N and L connect to the DC power source (e.g., battery) with positive and negative. A ground connection is shown. Output terminals N and L connect directly to the load (e.g., light bulb) for direct output. — Figure 3: DC12V/24V Power Supply Wiring Diagram. Connect the temperature sensor (L=1 meter) to its designated port.

Wiring Steps:

Power Input: Connect your DC12V or DC24V power source to the "enter" terminals (N and L). Ensure correct polarity (+ and -).
Load Output: Connect your heating or cooling device (load) to the "output" terminals (N and L). The W3103 provides direct voltage output to control the load.
Grounding: If applicable, connect the ground wire to the designated ground terminal.
Temperature Sensor: Connect the NTC temperature sensor (L=1 meter) to the sensor input port. Ensure it is securely connected and placed in the environment where temperature needs to be measured.

Caution: For AC220V models, wiring will differ. Always consult a qualified electrician for AC installations to prevent electric shock and ensure safety.

6. Operating Instructions

The W3103 features a digital display and three buttons: "Start setting" (Up arrow), "Stop setting" (Down arrow), and "SET".

6.1 Button Functions Overview

Start Setting (Up Arrow): Used to increase values or initiate setting adjustments.
Stop Setting (Down Arrow): Used to decrease values or initiate setting adjustments.
SET Button:
- Short Press: Switches between working modes (Temperature Control, F1 Intermittent Work, F2 Scheduled Shutdown, F3 Scheduled Startup).
- Long Press (3+ seconds): Enters the Temperature Correction Setting.

6.2 Temperature Control Mode

Diagram showing the temperature control mode. The display shows real-time temperature. 'Start setting' and 'Stop setting' buttons are used to adjust the desired temperature range. Start indicator and Stop indicator LEDs are present. — Figure 4: Temperature Control Mode Interface.

After power-on, the middle of the screen displays the real-time temperature. If it's not showing a number, short press the SET button to switch to temperature control mode.

Setting Start Temperature: Press the "Start setting" (Up arrow) button. The start temperature display will flash. Use the Up/Down arrows to adjust the desired start temperature. The setting will automatically save after a few seconds of no operation.
Setting Stop Temperature: Press the "Stop setting" (Down arrow) button. The stop temperature display will flash. Use the Up/Down arrows to adjust the desired stop temperature. The setting will automatically save after a few seconds of no operation.

The device will activate the output when the temperature reaches the start setting and deactivate when it reaches the stop setting, or vice-versa, depending on whether it's configured for heating or cooling.

6.3 Intermittent Mode (F1)

Diagram showing the intermittent mode (F1). The display shows timing boot code. 'Start setting' and 'Stop setting' buttons are used to adjust start and stop times in minutes. Start indicator and Stop indicator LEDs are present. — Figure 5: Intermittent Mode (F1) Interface.

Short press the SET button until "F1" is displayed in the middle of the screen.

Setting Start Time (Minutes): Press the "Start setting" (Up arrow) button. The start time display (minutes) will flash. Use the Up/Down arrows to adjust the desired ON duration.
Setting Stop Time (Minutes): Press the "Stop setting" (Down arrow) button. The stop time display (minutes) will flash. Use the Up/Down arrows to adjust the desired OFF duration.

The device will cycle the output based on the set ON and OFF durations.

6.4 Timing Shutdown Mode (F2)

Diagram showing the timing shutdown mode (F2). The display shows the hour and minutes of the boot time. 'Start setting' and 'Stop setting' buttons are used to adjust the hour and minutes respectively. Start indicator and Stop indicator LEDs are present. — Figure 6: Timing Shutdown Mode (F2) Interface.

Short press the SET button until "F2" is displayed in the middle of the screen.

Setting Shutdown Hour: Press the "Start setting" (Up arrow) button. The hour digits will flash. Use the Up/Down arrows to adjust the desired shutdown hour.
Setting Shutdown Minute: Press the "Stop setting" (Down arrow) button. The minute digits will flash. Use the Up/Down arrows to adjust the desired shutdown minute.

The device will operate normally and then shut down after the set duration.

6.5 Timing Boot Mode (F3)

Short press the SET button until "F3" is displayed in the middle of the screen.

Setting Boot Hour: Press the "Start setting" (Up arrow) button. The hour digits will flash. Use the Up/Down arrows to adjust the desired boot hour.
Setting Boot Minute: Press the "Stop setting" (Down arrow) button. The minute digits will flash. Use the Up/Down arrows to adjust the desired boot minute.

The device will remain off and then power on after the set duration.

6.6 Temperature Correction Function

Diagram showing the temperature correction function. The display shows a temperature correction code (BCAJ) and the correction difference. Long press SET to enter, then use Up/Down arrows to adjust the difference value. — Figure 8: Temperature Correction Function Interface.

If there is a discrepancy between the displayed temperature and the actual temperature (measured by a calibrated thermometer), you can use the temperature correction function.

Enter Correction Setting: Long press the SET button for more than 3 seconds. The display will show a temperature correction code (e.g., "BCAJ") and the current correction difference.
Adjust Correction Value: Use the "Start setting" (Up arrow) and "Stop setting" (Down arrow) buttons to adjust the temperature difference value. This value will be added to or subtracted from the measured temperature.

The setting will automatically save after a few seconds of no operation.

7. Maintenance

Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
Sensor Care: Ensure the temperature sensor is clean and free from debris. Do not bend or damage the sensor cable.
Connections: Periodically check all wiring connections to ensure they are secure.

8. Troubleshooting

Problem	Possible Cause	Solution
Device does not power on	No power supply; incorrect wiring; faulty power source.	Check power connections; verify power source is active; ensure correct voltage (DC12V/24V/AC220V) is applied.
Incorrect temperature reading	Sensor faulty or improperly placed; temperature correction needed.	Check sensor connection and placement; use the temperature correction function (Section 6.6) to calibrate.
Output not activating/deactivating	Incorrect temperature settings; faulty load; wiring issue.	Verify start/stop temperature settings; check load functionality; inspect output wiring.
Mode not changing	SET button not pressed correctly.	Ensure a short press for mode cycling or a long press for temperature correction.

9. User Tips

For critical applications, always use an independent thermometer to verify the W3103's readings, especially after initial setup or if temperature fluctuations are observed.
When setting timing functions, double-check the hours and minutes to avoid unintended operation.
Consider using a protective casing for the controller if it's exposed to dust or moisture in its operating environment.
