4. Contingut del paquet
- W3103 Digital Temperature Controller (x1)
Note: The NTC temperature sensor is typically integrated or included with the controller.
5. Configuració i cablejat
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)

Passos de cablejat:
- Entrada d'alimentació: Connect your DC12V or DC24V power source to the "enter" terminals (N and L). Ensure correct polarity (+ and -).
- Sortida de càrrega: Connect your heating or cooling device (load) to the "output" terminals (N and L). The W3103 provides direct voltage output to control the load.
- Posada a terra: If applicable, connect the ground wire to the designated ground terminal.
- Sensor de temperatura: 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. Instruccions de funcionament
The W3103 features a digital display and three buttons: "Start setting" (Up arrow), "Stop setting" (Down arrow), and "SET".
6.1 Funcions dels botons anteriorsview
- Start Setting (Up Arrow): Used to increase values or initiate setting adjustments.
- Stop Setting (Down Arrow): Used to decrease values or initiate setting adjustments.
- Botó SET:
- Premsa curta: 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 Mode de control de temperatura

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)

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)

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

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.
